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.
