Setting the Reservation Policy
If you use PowerHA 7.1, set the reserve_policy attribute to no_reserve. If
you use a version of PowerHA other than PowerHA 7.1, we recommend that
you set the reserve_policy attribute to PR_exclusive. Note that if a virtual
I/O function is applied in order to use PowerHA in a client partition, use the
following procedure to check, in the virtual I/O server partition, the settings
for the reserve_policy attribute of the hdisk. If reserve_policy is set to
PR_exclusive, change its value to no_reserve.
