Creating a volume set

Volume Sets enable the use of the Multi-Volume Support feature with Veritas File System (VxFS). It is also possible to use the Veritas Enterprise Administrator (VEA) to create and administer volumes sets. For more information, see the VEA online help.

Before creating a volume set, make sure the following conditions are met:

Usage notes

  • Before creating a volume set, you must have at least one volume created.

    See Creating a volume .

  • A maximum of 256 volumes may be configured in a volume set.

  • Only Veritas File System is supported on a volume set.

  • The first volume in a volume set must be larger than 20MB.

  • Raw I/O from and to a volume set is not supported.

  • Volume sets can be used instead of volumes with the following vxsnap operations on instant snapshots: addmir, dis, make, prepare, reattach, refresh, restore, rmmir, split, syncpause, syncresume, syncstart, syncstop, syncwait, and unprepare. The third-mirror break-off usage model for full-sized instant snapshots is supported for volume sets provided that sufficient plexes exist for each volume in the volume set.

    See the Veritas Volume Manager Administrator's Guide.

  • Most VxVM commands require superuser or equivalent privileges.

  • For details regarding usage of the vxvset command, see the vxvset(1M) manual page.

To create a volume set for use by Veritas file system (VxFS)

For example, to create a volume set named db01vset that contains the volume db01, in the disk group PRODdg, you would use the following command:

# /opt/VRTS/bin/vxvset -g PRODdg -t vxfs make db01vset db01
