Creating and
administering
volume sets
This chapter describes how to use the vxvset command to create and administer
volume sets in Veritas Volume Manager (VxVM). 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.
For full details of the usage of the
vxvset command, see the vxvset(1M) manual
page.
Note: Most VxVM commands require superuser or equivalent privileges.
Please note the following limitation of volume sets:
■ A maximum of 2048 volumes may be configured in a volume set.
■ Only Veritas File System is supported on a volume set.
■ The first volume (index 0) in a volume set must be larger than the sum of the
total volume size divided by 4000, the size of the VxFS intent log, and 1MB.
■ Raw I/O from and to a volume set is not supported.
■ Raw I/O from and to the component volumes of a volume set is supported
under certain conditions. See “Raw device node access to component
volumes” on page 364 for more information.
■ Resizing a volume setwith an unmounted file system is not supported.
