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 utilit y that com es with the HP MPIO EVA DSM package
to remove the
stray reservations. For more information on how to use this utility, see HP MPIO EVA
DSM persistent reservations clear utility.
