... virtualDiskNamen
]) reservations

Synchronizing RAID Controller Module Clocks
To synchronize the clocks on both RAID controller modules in a storage array
with the host clock, run the following command:
set storageArray time
Locating Physical Disks
At times, you might need to locate a specific physical disk. In very large
storage array configurations, this can sometimes be awkward. If you need to
locate a specific physical disk, turn on the indicator LED on the front of the
physical disk. To turn on the indicator LED on a physical disk, run the
following command:
start physicalDisk [
enclosureID,slotID
] blink
To turn off the indicator LED after locating the physical disk, run the
following command:
stop physicalDisk blink
Performance Tuning
Over time, as a storage array exchanges data between the hosts and physical
disks, its performance can degrade. Monitor the performance of a storage
array and make adjustments to the storage array operational settings to
improve performance.
