Enable Mirrored Disk
Warning:
Using this command may cause a mirror set copy. Read all
instructions in this section
before
using this command.
This command attempts to enable a mirrored SCSI disk, indicated by
Disk
x
, that is
disabled
or
faulted.
The disk is enabled without having to reboot the IOP under most circumstances.
A disk is faulted when it cannot respond to a read or write request. The disk’s failure to respond
to a read or write request may be transient or permanent.
This command is used to enable a disk following a repair or replacement. For instructions about
how to replace a disk, refer to
Replacing a Failed Mirrored Disk
on page
9-27
.
A disk experienced read or write errors and was deemed to be
faulted
, then the
faulted
state
would remain across IOP reboots, even if you replaced the faulted disk. In this case, you must
explicitly enable the disk to clear its
faulted
condition.

Results
The disk remirroring process is initiated, if necessary. If a disk is

remains
offline
until the copy begins; it does not transition to
online
until the
mirror copy begins.
If this command does not succeed, examine the event log for details.
