Disabling a Mirror




	NOTE: Disabling a mirror can result in loss of data redundancy.

This procedure disables a mirror by temporarily detaching the mirror from its volume. A detached mirror is inaccessible for reads and writes, but is still associated with its volume. Once disabled, the mirror remains detached from its volume until you either reattach the mirror (see “Repairing a Mirror”) or restart the volume.

To disable a mirror in a volume

Select the volume that contains the mirror to be disabled.
Choose Volumes > Mirror > Disable (Selected menu) or Mirror Disable (Command Launcher).

Complete the Disable Mirror dialog box as follows:

Select a mirror to disable:

Select the mirror to be disabled.

When you have provided all necessary information in the dialog box, click OK.

Notes:
When a mirror is disabled, volume reads and writes cannot be directed to the mirror. If a volume only has two mirrors and one mirror is disabled, the volume is not redundant while the mirror is disabled. The last mirror in a volume cannot be disabled. When a volume is restarted, any disabled (detached) mirrors should be reattached to the volume automatically.
