Preliminary Information for Renaming Metadevices

• DiskSuite enables you to rename a metadevice at any time, as long as the name being used is not in use by another metadevice, and as long as the metadevice itself is not in use.

• Before renaming a metadevice, make sure that it is not currently in use. For a file system, make sure it is not mounted or being used as swap. Other applications using the raw device, such as a database, should have their own way of stopping access to the data.

• You can rename any metadevice except a metadevice that is being used as a logging device. To perform the equivalent of renaming a metadevice used as a logging device, detach the logging device then reattach a new logging device of the desired name. Or detach the logging device, rename it, then reattach it to the trans metadevice.

• You cannot rename a trans metadevice while it has an attached logging device. To rename a trans metadevice, first detach the logging device.

• Hot spare pools cannot be renamed once they are created.

• Metadevices within a diskset can be renamed. You cannot rename metadevices from one diskset to another.

The metarename command with the -x option can "switch" metadevices that have a parent-child relationship. Refer to "Metadevice Name Switching".
