Example—Renaming a Volume Used for a File System

# 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

In this example, the volume d10 is renamed to d100. Because d10 contains a mounted file system, the file system must be unmounted before the rename can occur. 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, the following line:

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

should be changed to:

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

Then, the file system should be remounted.

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 (RAID 0, RAID 1, or RAID 5 volume), you can keep data on that volume.
