Renaming volumes or switching volume names is an administrative convenience for management of volume names. For example, you could arrange all file system mount points in a desired numeric range. You might rename volumes to maintain a naming scheme for your logical volumes or to allow a transactional volume to use the same name as the underlying volume had been using.
Before you rename a volume, 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.
Specific considerations for renaming volumes include the following:
You can rename any volume except the following:
Volumes on which soft partitions are directly built
Volumes that are being used as log devices
Hot spare pools
You can rename volumes within a disk set. However, you cannot rename volumes to move them from one disk set to another.
You can use either the Enhanced Storage tool within the Solaris Management Console or the command line (the metarename(1M) command) to rename volumes.
