show autorebuild

This feature only applies to 9550SX and 9590SE 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 51.

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

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> /c0 show unitstatus

Unit UnitType Status %Cmpl Stripe Size(GB) Cache AVerify IgnECC

-------------------------------------------------------------------------

u0 RAID-5 OK - 64K 223.485 OFF OFF ON

u1 JBOD OK - - 76.3352 OFF OFF -

u2 RAID-0 OK - 64K 148.99 ON ON -

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.
