Example of interactive mode:

//localhost> /c0/u0 del

Deleting /c0/u0 will cause the data on the unit to be

permanently lost.

Do you want to continue ? Y|N [N]:

start rebuild disk=

p<p:-p...>

[ignoreECC]

This command allows you to rebuild a degraded unit using the specified

disk=p. Rebuild only applies to redundant arrays such as RAID 1, RAID 5,

RAID 6, RAID 10, and RAID 50.

During rebuild, bad sectors on the source disk will cause the rebuild to fail.

RAID 6 arrays are less susceptible to failing since two copies of the data exist.

You can allow the operation to continue by using ignoreECC.

The rebuild process is a background task and will change the state of a unit to

REBUILDING. Various show commands also show the percent completion as

rebuilding progresses.

Note that the disk used to rebuild a unit (specified with disk=p) must be a

SPARE or a unconfigured disk. You must first remove the degraded drive(s)

before starting the rebuild. Refer to the command “/cx/px remove [noscan]

[quiet]” on page 84 for details. Also refer to the command “/cx rescan

[noscan]” on page 50 to add new drives or to retry the original drive.

If you are rebuilding a RAID 50, RAID 6, or RAID 10 unit, multiple drives

can be specified if more than one sub-array is degraded.

When you issue this command, the specified rebuild will begin if schedules

are disabled; otherwise it will pause until the next scheduled rebuild. A file

system check is recommended following rebuild when using the ignoreECC

option.

start verify

This command starts a background verification process on the specified unit

/cx/ux. The following table shows the supported matrix as a function of the

controller model and logical unit type.

N/A (Not Applicable) refers to cases where the given logical unit type is

not supported on that controller model.
