Volume Name Requirements

There are a few rules that you must follow when assigning names for volumes:

• Volume names must begin with the letter “d” followed by a number (for example, d0).

• Solaris Volume Manager has 128 default volume names from 0–127. The following table shows some example volume names.

  Table 3–3 Example Volume Names

  /dev/md/dsk/d0	Block volume d0
  /dev/md/dsk/d1	Block volume d1
  /dev/md/rdsk/d126	Raw volume d126
  /dev/md/rdsk/d127	Raw volume d127

• Instead of specifying the full volume name, such as /dev/md/dsk/d1, you can often use an abbreviated volume name, such as d1, with any meta* command.

• Like physical slices, volumes have logical names that appear in the file system. Logical volume names have entries in the /dev/md/dsk directory (for block devices) and the /dev/md/rdsk directory (for raw devices).

• You can generally rename a volume, as long as the volume is not currently being used and the new name is not being used by another volume. For more information, see Exchanging Volume Names.
