Usage Guidelines The WAAS software supports hot-swap functionality for both failed disk replacement and scheduled
disk maintenance. On the WAE-612 and WAE-7326, use the disk disk-name diskxx shutdown global
configuration command to shut down a disk for scheduled disk maintenance. On the WAE-7341 and
WAE-7371, use the disk disk-name diskxx replace EXEC command to shut down a disk. (For the
scheduled disk maintenance procedure, see the Cisco Wide Area Application Services Configuration
Guide, Chapter 14.)
The disk hot-swap functionality automatically disables a failed disk if the system detects one critical disk
alarm. The software removes the failed disk automatically regardless of the setting for disk
error-handling.
For WAE-7341 and WAE-7371 models, when you replace a failed disk that was automatically disabled
by the software, the disk automatically returns to service. For WAE-612 and WAE-7326 models, when
you replace a failed disk that was automatically disabled by the software, use the disk insert EXEC
command to bring the disk back into service. For all other models, see the (config) disk disk-name
command section.
To identify which disks have been identified as failed or bad, use the show disks failed-disk-id EXEC
command. Do not reinsert any disk with a serial number shown in this list.
Note The show disks failed-disk-id command is not available on WAE-7341 and WAE-7371 models.
Use the disk delete-partitions EXEC command to remove all disk partitions on a single disk drive on a
WAAS device or to remove the disk partition on the logical drive for RAID-5 systems.
Caution Be careful when using the disk delete-partitions EXEC command because the WAAS software treats
the specified disk drive as blank. All previous data on the drive will become inaccessible.
Note When you use the disk delete-partitions EXEC command on the WAE-7341 or WAE-7371 models, the
command deletes the entire logical volume. The individual disk name option is not available on these
platforms.
Examples The following example shows how to recreate the RAID-5 array:
