How to Rename a Volume

Before You Begin

Check the volume name requirements (Volume Names), and Background Information for Renaming Volumes.

1. Unmount the file system that uses the volume.

   # umount /filesystem

2. To rename the volume, use one of the following methods:

   • From the Enhanced Storage tool within the Solaris Management Console, open the Volumes. Select the volume you want to rename. Click the right mouse on the icon. Choose the Properties option. Then, follow the onscreen instructions. For more information, see the online help.

   • Use the following form of the metarename command:

     # metarename old-volume-name new-volume-name

     old-volume-name

     Specifies the name of the existing volume.

     new-volume-name

     Specifies the new name for the existing volume.

     See the metarename(1M) man page for more information.

3. Edit the /etc/vfstab file to refer to the new volume name, if necessary.

4. Remount the file system.

   # mount /filesystem

Example 20–3 Renaming a Volume Used for a File System

In the following example, the volume, d10, is renamed to d100.

# umount /home
# metarename d10 d100
d10: has been renamed to d100
(Edit the /etc/vfstab file so that the file system  references the new volume)
# mount /home

Because d10 contains a mounted file system, the file system must be unmounted before the volume can be renamed. If the volume is used for a file system with an entry in the /etc/vfstab file, the entry must be changed to reference the new volume name.

For example, if the /etc/vfstab file contains the following entry for the file system:

/dev/md/dsk/d10 /dev/md/rdsk/d10 /docs home 2 yes -

Change the entry to read as follows:

/dev/md/dsk/d100 /dev/md/rdsk/d100 /docs home 2 yes -

Then, remount the file system.

If you have an existing mirror or transactional volume, you can use the metarename -x command to remove the mirror or transactional volume and keep data on the underlying volume. For a transactional volume, as long as the master device is a volume ( either a RAID-0, RAID-1, or RAID-5 volume), you can keep data on that volume.
