Volume Name Requirements and Guidelines

The custom JumpStart installation method automatically assigns volume names to RAID-0 submirrors during the installation. You can optionally assign a name to RAID-1 volumes (mirrors) with the filesys JumpStart keyword.

Observe the follwoing rules when assigning names for volumes.

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

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

To simplify the administration of volumes, consider using the following standard naming conventions.

• Use ranges for each particular type of volume. For example, assign numbers 0–20 for RAID-1 volumes, and 21–40 for RAID-0 volumes.

• When you use Solaris Live Upgrade to create mirrors, use a naming relationship for mirrors. You can name mirrors with a number that ends in zero (0), and submirrors that end in one (1) and two (2). Examples are mirror d10, submirrors d11 and d12, and mirror d20, submirrors d21 and d22.

  When you use the custom JumpStart installation method to create mirrors, the submirrors are automatically assigned a name that corresponds to the name of the mirror.

• Use a naming method that maps the slice number and disk number to volume numbers.

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

  • Device /dev/md/dsk/d0 — block volume d0

  • Device /dev/md/dsk/d1 — block volume d1
