Using Removable Disk Management

This section describes how to remove or add disks with the hot removability feature. Hot removability allows you to remove or add disks without turning the system off. This feature is only available on certain systems. For more information, refer to 7013 J Series Operator Guide for details on the hot removability feature. For details on physical removal and insertion of disks, see 7013 J Series Service Guide.

• Remove a disk in a separate non-rootvg volume group for security or maintenance purposes. (See Removing a Disk with Data Using the Hot Removability Feature .)
• Permanently remove a disk from a volume group. (See Removing a Disk without Data Using the Hot Removability Feature .)
• Add a disk. (See Adding a Disk Using the Hot Removability Feature .)
• Correct a disk failure. (See Recovering from Disk Failure Using the Hot Removability Feature .)
