-D <logical_drive_num>
-s <physical_drive_id>
To delete the spare drive from the specified logical drive.
-D <logical_drive_num>
-s all
To delete all of spare drives from the specified logical drive.
-D <logical_drive_num>
To delete the specified logical drive.
-D <logical_drive_num>
-f
To delete the specified logical drive, bypassing Data Critical Usage report from CRA
(Critical Resources Analysis).
-D all To clear configuration.
-C <read_caching_percentage>
To specify the percentage of total cache size to be used for read caching. The
remaining percentage will be used for write caching. Valid read caching percentage
numbers are 0, 25, 50, 75, and 100 (%).
-F on To enable auto-fail missing disks at boot feature.
-F off To disable auto-fail missing disks at boot feature.
-I -p <physical_drive_id> [
-p <physical_drive_id>...]
To identify SAS/SATA physical drive(s) by LED.
-I -l <logical_drive_num>
To identify a SAS/SATA logical drive by LED.
-E <logical_drive_num>
-c <capacity>
To extend the capacity of the specified logical drive up to larger capacity. The capa-
city is in GB.
-E <logical_drive_num>
-p <physical_drive_id> [-p <phys_drive_id>...]
To expand the specified logical drive and others in an array by physical drive(s).
-M <logical_drive_num>
-R <RAID_level> [-S <stripe_size>]
To perform RAID level [with stripe size] migration on the specified logical drive.
The stripe size is in KB.
-M <logical_drive_num>
-S <stripe_size>
To perform stripe size migration on the specified logical drive. The stripe size is in
KB.
Logical Drive State Definitions
OK All physical disks in the logical drive are operational.
FAILED Some possible causes:
1) Multiple physical disks in a fault-tolerant (RAID 1, 1+0, 5, ADG) logical drive have
failed.
2) One or more disks in a RAID 0 logical drive have failed.
3) Cache data loss has occurred.
4) Array expansion was aborted.
5) The logical drive is temporarily disabled because another logical drive on the controller
had a missing disk at power-up.
USING INTERIM RECOVERY MODE
Also known as "degraded" state. A physical disk in a fault tolerant logical drive has failed.
For RAID 1, 1+0 or 5, data loss may result if a second disk should fail. For RAID ADG, data
loss may result if two additional disks should fail.
READY FOR RECOVERY OPERATION
A replacement disk is present, but rebuild hasn’t started yet (another logical drive may be
currently rebuilding). The logical drive will also return to this state if the rebuild had been
aborted due to unrecoverable read errors from another disk.
RECOVERING
One or more physical disks in this logical drive are being rebuilt.
