*** emc_reserve_v2.sh ***

Begining in ODM 5.3.0.4 there was a script added to the ODM package
called emc_reserve_v1.sh. This utility supports updating the hdisk
device reserve attributes in predefined PdAt ODM object class.
The object of the script is to change the default hdisk reserve settings
from reserve enabled to disabled. Support has been added for both Symmetrix
and CLARiiON standard FCP and FCP MPIO devices.

The script is located in the following directories
/usr/lpp/EMC/Symmetrix/bin
/usr/lpp/EMC/CLARiiON/bin

Beginning in ODM 5.3.0.6 and 6.0.0.1 there is an update to the script to support
PowerPath 5.5 reserve_policy and PR_key_value entries.

To disable the reserve policy run the following command emc_reserve_v2.sh

After the changes are made it will only take affect for devices that are added 
to the AIX system. Previous configured devices will still require you to manually
change the device attributes.

*** IMPORTANT **** This script is not persistant across ODM upgrades which
implies that going to a new ODM version requires the script to be ran again.
For instance upgradig from ODM 5.3.0.5 to 5.3.0.6 requires the script to be ran
after the upgrade.
