Command View VLS navigation tree following the removal of a disk array or enclosure.
CAUTION:
Follow the procedure in
“Removing VLS Capacity” (page 44)
when removing an
array from the system or removing an enclosure from an array.

Navigate to the Manage Virtual Disks screen (see
“Managing Disk Arrays” (page 122)

The screen displays a message that the reset has completed successfully.
Setting the RAID Mode
If your VLS is located at a remote data center and failed hard drives cannot be replaced in a timely
manner (48 to 72 hours), you can set the global VLS RAID6 configuration to include a hot-spare
for each RAID set. This feature allocates one spare hard drive per enclosure that will automatically
take over for a failed drive. After you replace the failed drive, the new drive becomes the spare.
CAUTION:
This feature requires running the Rebuild All Storage Pools operation. Rebuild All
Storage Pools destroys all current virtual tape cartridges in the system. HP recommends only
changing this mode on a new installation before creating any virtual cartridges.
To change the RAID mode, in Command View VLS:
1.
Navigate to the Manage Virtual Disks screen (see
“Managing Disk Arrays” (page 122)
).
2.
Select Set RAID Mode from the task bar.
3.
Select the RAID Mode.
•
Default – No Hot-spare: the system uses a 10+2 configuration where ten disks are part
of the available virtual disks and two are parity disks.
•
Hot-spare: the system uses a 9+2+1 configuration where nine disks are part of the
available virtual disks, two are parity disks, and one is a hot-spare disk.
NOTE:
Using the hot-spare mode reduces the VLS capacity and performance by 10%.
