Changing The Rebuild Priority Of A Logical Drive; Specifying The Percentage Of Cache Used For Read Caching; Auto-Fail Missing Disks At Boot; Creating Multiple Logical Drives In An Array - HP Smart Array -UX 11i v2 Support Manual

Changing the rebuild priority of a logical drive

To set the rebuild priority of logical drives, use the saconfig /dev/cissX -r <low | medium
| high> command.
For example:
# saconfig /dev/ciss5 -r high
In this example, the rebuild priority is set to high for the logical drives under controller ciss5.

Specifying the percentage of cache used for read caching

To specify a percentage of cache to be used exclusively for read caching, use the saconfig
/dev/cissX -C <read_caching_percentage> command.
For example:
# saconfig /dev/ciss5 -C 100
Read cache percentage changed to 100%
You can set the <read_caching_percentage> to 0, 25, 50, 75, or 100 percent of the cache.

Auto-fail missing disks at boot

To enable or disable auto-fail of missing disks at boot, use the saconfig /dev/cissX -F
on|off command.
For example:
# saconfig /dev/ciss5 -F on
Auto-fail missing disks enabled

Creating multiple logical drives in an array

To create multiple logical drives in an array, use the command:
saconfig /dev/cissX -R <RAID level> -p <physical drive id> [-p <physical
drive id> ...]-c <capacity in GB>
For example:
# saconfig /dev/ciss5
Logical drive 0 created
Rebuild priority is set to High
NOTE: If you do not specify a capacity using -c <capacity in GB>, the maximum capacity
or the remaining capacity in the array is applied to the logical drive.

Performing RAID level migration

To migrate an existing logical drive to a different RAID level, use the command:
saconfig /dev/cissX -M <Logical drive #> -R <RAID level> [-S <Stripe
size (KB)>]
For example:
# saconfig /dev/ciss5 -M 0 -R 5
Logical drive 0 migrated from ADG to 5
Migrating a logical drive to a different RAID level does not change its capacity.
NOTE: If you do not specify a stripe size using -S <Stripe size (KB)>, the default stripe
size is used.
