Event Name: Tailored VMAX3 Config Mgmt w-Vmax3 BC 5-18-5-21 (MLL642463) Start Time: May 18, 2015 10:00:00 PM File Saved by: Ashok Reddy Date Time: May 22, 2015 3:16:11 AM Larry: We may have lost those students ashok: yes Anuraj: Sped test may not be good, since we log into work and the VPN dials down the speed Anuraj: I am in US, and I had issues ashok: but we are not using any videos except yours, i think Kranthi: Anuraj, are you on wireless? Anuraj: yes Kranthi: perhaps you want to try direct ethernet Salauddin: I am in UK ashok: NO, i m from Singapore Doug N.: It probably wants to syncronize everyone expecting it to allow bi-directional conferencing. Salauddin: no probs on my line ashok: i m not i VPN and i have 300Mbps Fibre line Anuraj: If I have issues, I can log in without VPN Anuraj: ok, Anuraj: logging off now ashok: yes Abdul: OK Salauddin: fine for me Krishna: ok Salauddin: yes Shailesh: some how the video resolution is not good but can see teh box Shailesh: I did my speed test without vpn is 23Mbps ashok: mine is 88.45Mbps Shailesh: dallas Anuraj: I am back now Larry: You are lagging Doug N.: There it goes. :-( Doug C: yep for me too Shailesh: Are you seeing slowdown Kery Hines: Yep you are lagging Doug C: must be your end Kranthi: yes . now.. Kranthi: Anuraj .. did u use ethernet or wireless Doug N.: Must be Anuraj's fault. ;-) Kery Hines: lags when you get in front of the whiteboard Kery Hines: no log Kery Hines: lag Kranthi: its fine now.. Shailesh: there eis glare on top right. is it feasible to write in middle of the board? Larry: Lost you Kery Hines: lagging utham: lost you Anuraj: we are losing you Doug C: lagging Doug C: this isn't working well Shailesh: lagging Anuraj: yes Larry: You know which wwpn goes to which hosts Shailesh: it allows for using teh same ig for local luns Larry: oops ashok: SPF Shailesh: allows for soem host to see more paths Shailesh: and some less paths Anuraj: what do you mean change port group ? Anuraj: yes Sid: yes Shailesh: are you associating PG to differnet SRP and LSO Larry: No Kranthi: can u add both pgs and once online can u remove goldpg Kranthi: ok Shailesh: Why cann't I create a new MV with same IG and new PG Jefferson: Lost soiund Larry: So you can add or remove ports from a PORT Group on line Kranthi: yes Doug N.: I can hear you fine. Abdul: yes Sid: yes Jefferson: I will reboot Shailesh: don't you have tod remove corresponding disk from host related t that FA in PG before you remove that FA from PG ( assuming 1MV existing on that PG for that Host) Shailesh: that path still constitute a hdsik under hdiskpower Jefferson: After reboot Shailesh: what si the max limit for IG/PG/SG/luns Shailesh: thanks Shailesh: deafult Kranthi: optimized Shailesh: optimized Kery Hines: opt Anuraj: default = optimized Kranthi: nvm Doug C: optimized Anuraj: no Krishna: no Shailesh: as all teh symdev are collectingfast uner SG so it doesn't matter Shailesh: is there a slide explaing the IO distribution layout which yu had just explained Shailesh: can you provide that white paper link Shailesh: EMC needs to improve their search engine, we also face similar issue Shailesh: google works better Kranthi: 1 Kranthi: no.. Anuraj: no Anuraj: yes Anuraj: no multipathing Anuraj: 8000 Shailesh: yourno. of paths which wold depened on no. of hbas to FA's zoning in PG Shailesh: on AIX NPIV vioc this will be diffifcult to set Iolimit as 4 hbas are secondary hbas not used until LPM is used but have to be zoned Doug C: when would you not use dynamic? Anuraj: what is the use case for for iolimit? Cloud computing? Kranthi: would that be taken care by path mgmt software dynamic on failure? Shailesh: is there a way to allow IO limitr o SG Shailesh: instead of IOPS per path? Kranthi: ok Shailesh: what is teh default setting for Io limit Shailesh: how about bandwidth Anuraj: yes Shailesh: this is going to cuase more trouble then benfit Salauddin: apple keyboard Shailesh: cause Anuraj: I am here Salauddin: cant find prnt screen ashok: use snipper Salauddin: yes Jefferson: yes charlie: yes Sid: yes Jefferson: What CLI flags did you use? Jefferson: Inside joke Doug N.: Go ahead Jeff. Type all that in for us. Jefferson: Starting now Shailesh: Jeff is half way bit the bits 01000100.... Jefferson: :) Shailesh: Hi Anthony is there a way whereby if we don't want to set any Host IO limit to and SG , can this be done ? Jefferson: lost audio again? Anuraj: we hear him Jefferson: rebooting Kranthi: can u show the demo of it Kranthi: ok Kranthi: thx Shailesh: Sorry to ask the same question again if we don't have to set host limit do we run symsg -sg <> set iops_max NOLIMIT -dynamic always Jefferson: Does anyone know were ours are stored? Shailesh: thanks ashok: can i use restore the backup file to another SE Shailesh: nromally we have been seeting spc2/os2007/scs3 on teh FA's Shailesh: we have some hpux but very less Shailesh: we set v bt on the ig Doug N.: For Jeff: /gsmsan04/CWS-dirs/hostname/symmapps/vcm/backups/ Shailesh: in unisphere do we have to do zoning first to have WWN show on teh IG screen, if not can we add teh WWN manually when creating teh IG Jefferson: The best thing about EMC and always has been is your CLI Jefferson: No other vendor touches you guys Jefferson: Unix.... look before you type Jefferson: ls Shailesh: can we add t eh WWN manually Kranthi: what is the time lag it shows in unisphere after zoning..? Anuraj: lol Kranthi: ok Kery Hines: cool Doug N.: Can this be done as a sanity check without doing new masking? Doug N.: Are there plans to add it to the CLI? Kery Hines: Doubt is will be CLI feature as its running against U4V database. CLI does not have access to that Doug N.: Oh my. Jeff is in the majority. :-/ Jefferson: This coming from one of the best scripters I know. If we were a GUI only shop... WE WOULD HAVE NO AUTOMATION. Doug N.: So, if the U4V database is missing data (like it often does) then the suitability check won't be accurate. Doug N.: Ah. So, then the CLI would have easy access to the database. Doug N.: We'll be putting in the enhancement request. ;-) Jefferson: How do you convince EMC that their strongest point is their CLI, not their GUI Jefferson: Then how do you convince a management team that is not listening. Jefferson: A MS world that can't fix their mess Kery Hines: If all provisioning is moved to ViPR no need for CLI Kery Hines: Citi is pushing ViPR Kery Hines: CLI will be needed still even with ViPR for troubleshooting... Jefferson: Don't worry.... I will be gone in 5-10 years Shailesh: how would suitability check work if you are using Open replciation where it has already adat written on old array to new arary in just 2 hours. same holds true for a new server if they are doing host based migration Anuraj: o Anuraj: no Doug N.: Jeff, this is simple enough virtualization, right? Shailesh: Does vmax-3 has a single command to see t he total pool, usage and masked subscription Shailesh: I think it showed only luns cut ashok: can we get allocated capacity vs used capacity ? ashok: may be i allocated 500gb but used 100gb only ashok: confused...but ok Shailesh: how about devices like RDFA?DSE they still use the pool but can cuase the subcription to increase Shailesh: untill using a different SRP Anuraj: yes Doug C: so can you tell when it went out of compliance? Shailesh: can we decide the response time range Shailesh: those are not editable Anuraj: why rdf would impact erformance? Anuraj: Unless srdf/s Anuraj: yes Shailesh: what happens if the we see lots of out of compliance SG and SRP dashboard Im assume we get EMC engage to check Vmax-3 Shailesh: cpu/port load scores of 100% means it is too busy/ Shailesh: yes Shailesh: what if we are moving from differnet vendor array, would this still work ? Shailesh: woruldn't it choose the SLO Shailesh: that defetas teh prupose Shailesh: is there a way to figure out which Fa's are connected to fabric Shailesh: symcfg list -fa all -port ( old vmax) Anthony: symsan Anthony: symmsan Shailesh: the previous command doesn't show on vamx-3 Shailesh: is there but doesn't show if teh port is connected or not they chnage certaimn o/p Shailesh: thanks Shailesh: hi Kranthi: ok thx Kranthi: yes.. Kranthi: got it.. Kranthi: thanks. Shailesh: HiAnthony Shailesh: I had a quick question how to find from cli teh acual usable space in SRP from teh symdisk and its proetction Shailesh: symdisk -sid 0767 list -dskgrp_summary -by_engine –detail symcfg -sid 0767 show -srp SRP_1 -detail |more Shailesh: both no.s are off by few hundred gigs Shailesh: yep Shailesh: how to find teh protetcion of the diskgrup Shailesh: protection of the DG Shailesh: symcfg show -pool <> -thin -all -gb -detail doesn't work Kranthi: symcfg -sid 0767 list -pool Shailesh: thanks kranthi , I was trying to ceck with -srp diskgroup name Shailesh: Thanks Kranthi: np.. Kranthi: Anthony, do we have a command to see the relationship between tdats and SRPs? Anthony: Not that I'm aware of Anthony: The tdats are all associated with the SRP.. Anthony: unless you have two SRPs in which case you would be looking at which physicals were associated with each SRP, not the TDATs Kranthi: ok thanks Kranthi: Anthony- if adding volumes to existing sg which is already in mv.. suitable checek does not happen saying the sg is already in mv..? Kranthi: suitability check Kery Hines: FYI... We are deploying U4V V8.0.2.7 Larry: No they did not have scroll bars Shailesh: When you have time , i s there a way on cli to check if the Sg are in compliant or not (like what we see in GUI)? Kranthi: -by_pg -demand shows pg speed MB/s=2000 pn pg but each FA port is 8gbps so in total if we have 4 pgs we would expect to ahev 8*4gbps=32gbps but -demand shows only 2000MB/s=20mbps? Shailesh: In free time if you could go thourgh teh SG in teh calss on sun1a which is out of compliant on teh wroload dashboard Kranthi: yes Kranthi: 2000MB/s=20gbps sorry typo Shailesh: yes Jefferson: I can Kranthi: it would be really helpful if you could show us demo of BandWidth limitations and excceding that from host side and show us what happens..does it throttle the IO on host? Kranthi: or IO limitations etc..? Kranthi: ok thx Shailesh: I just emailed you teh SG out of complaint Shailesh: what isthe speed for teh infiband backedn Swithc network Shailesh: so on slic2, port4 ca be FE, 5 as RE and 6, 7 as FE Anuraj: little confusing Kranthi: why does it have local disk assigned insted of boot from san? that too from virtual hbas? Kranthi: ok Anuraj: which disk does it use? Anuraj: I know its HBA is from FA, correct? Anuraj: virtual HBA Anuraj: ok Anuraj: thx Doug N.: What speed do the virtual HBA/FA connections look like? ashok: does it required concatenated disk for SAN boot ? Anuraj: It is a virtual port: So it uses Cache Anuraj: ok ashok: ok Anuraj: What is use case for this? Kranthi: correct me if I am wrong so its 2 Vms per engine? Anuraj: ok Kranthi: so 2 is minimum per engine? Shailesh: Doesn't it cause a secuirty risk when you have IP world access within the array? Shailesh: Can we acces tools VM? Anuraj: So, unified is both VNX and VMA X. Anuraj: VMAX Anuraj: so hypermax upgrades, that will upgrade DART Anuraj: also? Anuraj: ok Anuraj: it willupgrade Hypervisor though Kranthi: silly q'n- hypervisor takes care of SAN and dart OS takes care of NAS? Anuraj: k Anuraj: this is pretty high tech. Shailesh: Can customer create the VM once licensed is installed ? Anuraj: best of both FC and ethernet. Very well converged Kranthi: yes Anuraj: I see some day, you running Linux VM's running inside this thing Anuraj: I know , but for databases Anuraj: because Oracle Super cluster has that Jefferson: The price of memory has fallen Anuraj: hyper convergance Anuraj: yes, Jefferson: So when you add datamovers, do you also add more hardware? Jefferson: Sorry, I lost sound when I hit enter... I think you said yes Kranthi: SLic8 isfor FE correct? Kranthi: ok Anuraj: they learned their lesson Shailesh: but DMX was robust hardware config Shailesh: DMX-3/4 Jefferson: Are you talking? Krishna: yes Salauddin: yes Doug N.: I can hear you. Doug N.: He's definitely not using his Mac. Jefferson: Citi MS virtual machine Jefferson: I have no control over the maching Doug N.: OMG. Why aren't you using your home PC? Doug C: i told you not to go thru cap Jefferson: It belongs to my wife Shailesh: use without the Citi VPN that might work Shailesh: better Jefferson: Virtualization is wonderful Anuraj: big tim Anuraj: e Shailesh: are we reffering to the local Replication pdf? Anthony: MR-1CP-VMAXBCM_Student Guide Shailesh: thanks Kranthi: which pdf is enas part of? Kranthi: ok Shailesh: shouldn't the dailbackup still poin to teh old track as of 11:45 Shailesh: so it shuold be plain yello color Shailesh: got it Kranthi: old pinka nd green are still old tracks as os 11:45AM rightr? Jefferson: Isn't technology wonderful... this doesn't happen with my wall phone! Sekhar Ati: Thats was me. My bad !! Apologies. I was trying to clear something that I wrote Kranthi: what is no penalty on copy on write with source vol mean ? Kranthi: yes.. Anuraj: yes Anuraj: yes Jefferson: I understand the different generations, but what / how to you set them, would not every write from Source make a new generation Jefferson: So with a script, you would create generation Jefferson: Thanks Shailesh: is delat teh difference of the tracks changed between Gen0 and gen1 Kranthi: use cases? that many 256 time stamps? Kranthi: when u have hourly why ned of yearly? Jefferson: So one host with many generations could eat the space on the array Jefferson: And it there a delete generation command Jefferson: So you are stopping a host's backups on the fly Doug N.: That's when Jeff get's more alert emails that he can ignore. Kranthi: which disks are assigned to Data domian Kranthi: ok.. Jefferson: But don't you have an incomplete back up... if shared track cracks Shailesh: what happens if you delete old gen, can you still restor Kranthi: is data domain mandatory for timefinder snapvx? Kranthi: ok Jefferson: This is a differential backup, and it needs a good source to work agaist. If the current source has a failed track, then you DON'T have a usable backup Jefferson: If the failed track is shared Anuraj: yes Jefferson: Do you have a redo log concept Jefferson: Always just before the server crashes Jefferson: True... my point is... you really don't have a clean seperate backup from the original... IE Tape, or a BCV Jefferson: So my server won't boot, so EMC will find the old copy of the track and to a copy over for me? Anuraj: Does it help with speed of backup and restore, a common complaints from the DBA's. Jefferson: Not trying to be difficult... see... you just proved my point... Not a seperate FULL backup from a point in time where disk corruption is not a factor Anuraj: For databases, though may not be good, due to consistency. Anuraj: pointer change Anuraj: no Jefferson: So, can you run a copy command once a day to ensure a complete copy Anuraj: yes Jefferson: That is a TRUE backup Doug N.: And COPY mode wastes a lot of space with little or no changes. Jefferson: Do you mind if we loose your deposit? Doug N.: You can lose data just as easy with COPY mode. Anuraj: does it help with databases, which have consistency issues? Anuraj: k Doug N.: Don't worry. I'll win. :-D Anuraj: no way Kranthi: since pointer needs to point to source tracks for any changes on it.. would'nt it cause the performance issue? also where are the bit-map changes kept is it in global cache? Kranthi: global memory? Kranthi: ok thx Anuraj: yes Anuraj: yes Anuraj: so to make 3 copies, make 1 copy and make 3 copies? Shailesh: does t his have to be in full copy mode Anuraj: copies - not right term Shailesh: so the first target is in copy mode and remaining 3 tgt from 1TGt are in no copy mode Anuraj: yes Doug N.: Yep. We're one of those banks. ;-) Jefferson: When you have scripts that pass audit , and keep the Feds off your back is very important Shailesh: what that measn people are not using snap? Kranthi: yes Shailesh: symlabel Kranthi: if new esx server why re-signature? Kranthi: ok if they belong to same cluster new esx? Kranthi: ok thx Anuraj: what is VMDK and VMK? Anuraj: k Anuraj: thx Kranthi: yes Kranthi: can u zoom in Kranthi: yes Kranthi: maximize? Shailesh: we r seeing ar 140% only Kranthi: nvm.. Kranthi: did it at my end..but its blurry Kery Hines: you can zoom in SABA Anuraj: what is intelligent hba? Anuraj: k Anuraj: thx Anuraj: yes Shailesh: thanks Larry: Please reload the ftp site Larry: on the screen Larry: I wanted the site address and uid;/pass on the screen Kranthi: ftp://VyUftp://VyUxqboM4:KABB76KBe6@ftp.emc.com User Name (login) VyUxqboM4 Password: KABB76KBe6 xqboM4:KABB76KBe6@ftp.emc.com User Name (login) VyUxqboM4 Password: KABB76KBe6 Anthony: Command line Connection Strings ftp ftp.emc.com User Name (login) VyUxqboM4 Password: KABB76KBe6 ---URL's- Windows Explorer URL ftp://VyUxqboM4:KABB76KBe6@ftp.emc.com Abdul: still doing the labs Abdul: are we suppose to do lab 3-8 today? Anuraj: Anthony: where is createfiles.sh script located? Abdul: Ok Anuraj: k. thx Anuraj: Anthony: u there? Anthony: yeah, go ahead Anuraj: what # can you be reached at Anthony? Anthony: +1 860-777-5246 Shailesh: one last question Shailesh: to terminate the restore from SRC to snapshot what is teh command Shailesh: and also fro unlink Shailesh: thnaks Sekhar Ati: No one thie morning?? Sekhar Ati: *this Sekhar Ati: Abdul: Not too many this morning? Sekhar Ati: We even beat Anthony :) Sekhar Ati: Just 4 of us? Sekhar Ati: Charlie/Shailesh: Did you hear from Anthony at all regarding any delays this morning? Abdul: lets wait few more minutes, we usually start after 8:30am Sekhar Ati: I just spoke to Anthony. He will join the class as usual at 10:00AM. Sekhar Ati: That would be 9:00AM for us. Abdul: ok Kranthi: Anthony- when restoring to source from modified target, can u creaste a snap shot of target and restore to source ? or this needs to be done by creating shanpshot of target and linking to source as the only way? Kranthi: also, when retoring to source can we do by linking to source insted of retoring to soruce from source snapshot?.. these 2 are a bit confusing? Shailesh: how to check the pool utilization for the snapvx Shailesh: Kranthi you can restore SRC directly from snapshot from SRC. I tried yesterday and it works Kranthi: okay.. thanks Kranthi: yes Shailesh: single command Shailesh: thanks Doug C: we were supposed to get it thru the week? Doug C: i asked that specifically on our calls Doug C: i had asked about having it the whole week for all our classes ashok: if it extend until weekend then it will be good for us as we can proctise Doug C: yes let me know who i need to talk to then Doug C: cathy or brian Sekhar Ati: DougC: Is she Cathy O'Connel? Sekhar Ati: *Isnt Doug C: yes Doug C: ok Shailesh: just one quest the symsnapvx can be run using file and DG Shailesh: in the man it showed on dg -file,-cg Shailesh: cg is across multipel symm Anuraj: unless use GNS ashok: what is the impact sas no cache I/O Sekhar Ati: Yes. But thats a heavy penalty at app/hos/hba level ashok: yes Sekhar Ati: until link is back Doug N.: Cache fills up. ashok: until cache/DSE Kery Hines: cache ashok: ok Shailesh: suspend Kery Hines: never kill a host Anuraj: loss of consistency Shailesh: when you say dedicated is teh whole slic Shailesh: thanks ashok: what about encription? Doug N.: That would be the same for FAs as for RAs? Doug N.: ok. wierd. Anuraj: still 58 is better than 32? Doug N.: How about 2 16G RAs and 2 16G FAs? Shailesh: offhnad grmas fE are 16Gbps but swithc is 8Gbps Shailesh: does it support cascaded SRDF/A Shailesh: thks Anuraj: repeat last statement please Anuraj: just the last piece Anuraj: k Doug N.: How often does it send FAST data? Everytime track moves? hourly/daily? Doug N.: OK. Makes sense. Shailesh: can you go to last slide Shailesh: for last bullet Shailesh: when you come back why you want Slo on R1 and R2 to be different as perf stats are provided to R2 from R1 so that incase if you invoke your cob it has the same perfromance as R1 side Kranthi: good q'n Shailesh. Shailesh: default it trys to keep teh same slo Shailesh: you can downgrade it if need on r2 Doug N.: Hex starts counting at 0. Decimal starts counting at 1. :-/ Shailesh: with Vmax-3 is SRDF/A allowed between differnet version of Vmax like vmax-20/40K(R 1 or R2)--->vmax-3 ( R1 or R2) Doug N.: Does VMAX3 still default to Sync mode (even on Async links)? Shailesh: is teh code modified where restore runs at same speed as estabslish Shailesh: microcode Shailesh: great ashok: once i perform failover then can it allowed to run establish Anuraj: ok. thx Kranthi: 2000? Kranthi: ok got it Doug N.: 1 LUN on both sides. Doug N.: (V2 is 1 LUN of 4 hyper Meta) Anuraj: k. thx Anuraj: k. thx Anuraj: what if link drops Anuraj: ok. thx Kranthi: in lab we do not ahve any vmdx etc files.. Shailesh: tx and rx are dependnet factor Shailesh: so thta time canbe >15sec Shailesh: so each capture cyclec is 15sec only irrespective of tx-Rx Shailesh: samdoes teh same hold for pply cycl Shailesh: Apply Anuraj: so it gives time lag Anuraj: more than just cycles Anuraj: k thx Anuraj: why suspend the link, just disable consistency on the group Anuraj: k. got it Shailesh: it is same as currently Anuraj: nameis misleading: transmit idle Anuraj: efd Anuraj: yes Anuraj: is there a command to show who is using my SRDF/A links themost. Anuraj: ok. thx Shailesh: don't we take snapshot on R2 befoer setting teh moe to acp Anuraj: what is compositegroup again? Anuraj: ok Shailesh: across multipel RDFG Anuraj: and we enable MSC on it. Anuraj: will it do a snapshot? Anuraj: k Shailesh: Does it allow hot push with remote device on the vmax-3 Anuraj: can u whiteboard little this more, I am not well familiar with OR too much. that is, If time allows. Kranthi: we do Or thru proxy likdn of setup by masking same devs to tareget FA's or new array FA's essentially similating like a host accessing IO.. how does array differentiate it betwen regular host io and OR io? is it just by OR commands Kranthi: got it.. Shailesh: so from OR perspetcive it works similar as what is now Shailesh: can you put that Pdf file on ftp site Anuraj: utilization = IOPS or bandwidth? Anuraj: %busy Anuraj: ok. thx Shailesh: does it have pace parameter also Doug N.: Yay. Shailesh: can you paste teh ftp siet address Anthony: ftp ftp.emc.com User Name (login) VyUxqboM4 Password: KABB76KBe6 ---URL's- Windows Explorer URL ftp://VyUxqboM4:KABB76KBe6@ftp.emc.com Doug C: thanks for getting the straightened out Doug N.: I've already swipped the whole FTP folder and put it on our team SharePoint. Anuraj: can you please put on your email and ph #. sorry for double effort Anthony: anthony.linkens@emc.com Anthony: +1 860-777-5246 Anuraj: which labs are we doing? Anuraj: ok Anuraj: both ESX and Sun Anuraj: ok Anuraj: Is there a lab for OR? Doug N.: There's no second local array. Anuraj: ok. Thanks. Jefferson: Thanks!
