Disk Maintenance
This section covers removing and replacing disk drives, and manual content removal.
For information about disk error handling, see the “Enabling Disk Error Handling” section on page 4-56.
Removing and Replacing Hard Disk Drives
In brief, the procedure for replacing a disk is simply to power down the unit, remove the disk, insert the
new disk, and reboot. During the reboot, the system automatically detects any new disks and seamlessly
allocates their space according to a simple disk-policy heuristic.
The disk policy’s design, when adding new disks, is to always favor safety. If when a new disk is added,
the disk manager detects “degraded” or “bad” sysfs volumes, the new disk will be used to repair the sysfs
volumes. Thus, the disk manager will always strive to have two disks allocated to the sysfs volumes. If
when a new disk is added, the sysfs volumes are “normal” or “syncing,” the new disk is added to the
cdnfs volume.
See Figure 8-2 for the disk numbering assignment.

Specifically, the procedure for removing a disk is different for the two types of disk volumes (sysfs and
cdnfs). The two procedures are outlined in the following sections.
Removing and Replacing a cdnfs Disk
To remove and replace a cdnfs disk, do the following:
Step 1 Stop all applications and unmount the drive by using the disk unuse command. This command stops and
restarts all applications that are currently using the specified disk drive (for example, disk02
[/local/local2] or disk03). All file systems, if applicable, will be unmounted on the specified disk.
The syntax of the command is as follows:
disk unuse diskname
