By default, the load balancing for the cluster devices is enabled and cannot be turned OFF.

Recovering i
naccessible disk devices
If there is a s
tray reservation on a disk device, the device becomes inaccessible to the host systems
connected to it. This is because the strong reservation type (persistent reservations) supports load
balancing in clusters.
You can use th
e persistent reservations clear utility that comes with the HP MPIO XP DSM package to
remove the s
tray reservations. For more information on how to use this utilit y, see HP MPIO XP DSM
persistent reservations clear utilit y section.
