Working With Disks
A disk:
• can be used as an individual element or as one of many disks in a
Redundant Array of Inexpensive Disks (RAID).
• can contain metadata information, journaling, and/or data.
• can constitute a single stripe group itself, or can be one node of a
multi-disk stripe group.
• can be a local hard disk located inside a server (if only a metadata
disk), or most commonly, used in a RAID visible to all machines in
the Storage Area Network (SAN) over FC.
The procedures in this section describe how to manage disks by adding,
deleting, and defragmenting disks. Each disk is assigned to a disk type
that specifies the number of sectors on the disk.

• Deleting Disks

Use this procedure to add a disk to a selected file system.
1 If the file system is mounted, unmount the file system as described in
Mounting or Unmounting a File System
on page 103.
2 If the file system is started, stop the file system as described in
Starting and Stopping the File System

Note: A disk must have a label before you can add it. For
information about labeling a disk, see Labeling a Device
