Veritas Storage Foundation for Oracle 5.0 Administrator's Guide, HP-UX 11i v3, Second Edition, December 2008

■ Before creating a volume set, you must have at least one volume

created.

See “Creating a volume ” on page 52.

■ 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.

Usage notes

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

◆

Use the following command:

# /usr/sbin/vxvset [-g diskgroup] -t vxfs make volset volume

where:

■ volset is the name of the volume set

■ volume is the name of the first volume in the volume set

■ -t defines the content handler subdirectory for the application that is to

be used with the volume. This subdirectory contains utilities that an

application uses to operate on the volume set. The operation of these

utilities is determined by the requirements of the application and not by

VxVM.

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:

# /usr/sbin/vxvset -g PRODdg -t vxfs make db01vset db01

Adding a volume to a volume set

After creating a volume set, you can add additional volumes.
