Viewing array information

4–15

The status of each disk drive in disk bays 1 to 12 is shown for SFS20 arrays. The disk drive status values

are described in Table 4-6. If any

predict fail

or

logging errors

failures are shown by the

show

array array_number

command, see Section 6.1.4.4 for information on how to confirm the actual status

of the disk. Note that the disk drive status is only updated while the preferred server for the array is running;

that is, if the preferred server is down, the disk drive status may be stale.

The status of the logical drive that underlies the LUN on the SFS20 array is shown in the

Logical Drive

field. The logical drive status values are described in Table 4-7.

replaced

This status indicates that an array that was previously connected to this port on the server

has been removed and a new array has been attached in its place. The information

about the detached array remains in the database; you can delete the array information

from the database using the

delete array array_number

command (see

Section 3.10 for more information).

Description

logging errors

There were new errors in the disk drive's log within the last 24 hours. For information on

handling disk errors on SFS20 arrays, see Section 9.34.

ok

The disk drive is operating normally.

predict fail

A S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) self-test predictive failure

error is recorded in the M&P data for this disk drive. For information on handling disk errors

on SFS20 arrays, see Section 9.34.

removed/failed

The disk drive has been removed or has failed. For information on handling disk errors on

SFS20 arrays, see Section 9.34.

Table 4-7

Logical drive status values

State

Description

ok

The logical drive is operating normally.

failed

The logical drive has failed. This usually indicates that there was a

triple disk failure where ADG redundancy is used, or a double

disk failure where RAID5 redundancy is used.

recovery in progress

The logical drive is being rebuilt. The logical drive is rebuilt when

a disk drive is removed or fails and a spare disk drive is

available; and when a disk drive is replaced.

recovery in use

The logical drive is operating in degraded mode because a disk

drive was removed or failed and there is no spare disk drive. In

such a case, you must replace the failed or removed disk drive as

soon as possible, because if a second disk drive fails, it will cause

the entire logical drive to fail.

recovery ready

The logical drive is ready to rebuild, but is waiting for another

logical drive to finish rebuilding (the logical drive that is currently

rebuilding will have the

recovery in progress

status). This

is a temporary status and will change to

recovery in

progress

when the logical drive starts rebuilding.

parity initializing

RAID parity initialization has started on the array but has not been

completed. The parity initialization process is started (by the

configure array

command) when an array is first configured.

Performance of an array is not optimal until parity initialization is

complete.
