/c

show autorebuild
This feature only applies to 9550SX, 9590SE, and 9650SE model controllers.
This command shows the Auto-Rebuild policy. If the policy is enabled, the
firmware will select drives to use for rebuilding a degraded unit using the
following priority order. For more information, see “/cx set
autorebuild=on|off” on page 57.
1. Smallest usable spare.
2. Smallest usable unconfigured (available) drive.
3. Smallest usable failed drive.
If the policy is disabled, only spare drives will be used for an automatic
rebuild operation.
Example:
//localhost> /c0 show autorebuild
/c0 Auto-Rebuild Policy = on
/c
x
show unitstatus
This command presents a list of units currently managed by the specified
controller /cx, and shows their types, capacity, status, and unit policies.
Possible statuses include: OK, VERIFYING, VERIFY-PAUSED,
INITIALIZING, INIT-PAUSED, REBUILDING, REBUILD-PAUSED,
DEGRADED, MIGRATING, MIGRATE-PAUSED, RECOVERY,
INOPERABLE, and UNKNOWN. (Definitions of the unit statuses are
available in the 3ware Serial ATA RAID Controller User Guide.)
Example:
//localhost> /c2 show unitstatus
Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache AVrfy
-------------------------------------------------------------------------
u0 RAID-5 OK - - 64K 596.004 ON OFF
u1 RAID-0 OK - - 64K 298.002 ON OFF
u2 SPARE OK - - - 149.042 - OFF
u3 RAID-1 OK - - - 149.001 ON OFF
Note: If an asterisk (*) appears next to the status of a unit, there is an error on one
of the drives in the unit. This feature provides a diagnostic capability for potential
problem drives. The error may not be a repeated error, and may be caused by an
ECC error, SMART failure, or a device error. Rescanning the controller will clear the
drive error status if the condition no longer exists.
