# vxassist [-g diskgroup] settag volume tagname[=tagvalue]

# vxassist [-g diskgroup] replacetag volume oldtag newtag

# vxassist [-g diskgroup] removetag volume tagname

To list the tags that are associated with a volume, use the following command:

# vxassist [-g diskgroup] listtag volume

To list the volumes that have a specified tag name, use the following command:

# vxassist [-g diskgroup] list tag=tagname volume

Tag names and tag values are case-sensitive character strings of up to 256

characters. Tag names can consist of letters (A through Z and a through z),

numbers (0 through 9), dashes (-), underscores (_) or periods (.) from the ASCII

character set. A tag name must start with either a letter or an underscore. Tag

values can consist of any character from the ASCII character set with a decimal

value from 32 through 127.

If a tag value includes any spaces, quote the specification to protect it from the

shell, as shown in the following command:

# vxassist -g mydg settag myvol "dbvol=table space 1"

Dotted tag hierarchies are understood by the list operation. For example, the

listing for tag=a.b includes all volumes that have tag names that start with a.b.

The tag names site, udid and vdid are reserved and should not be used. To avoid

possible clashes with future product features, do not start tag names with any of

the following strings: asl, be, isp, nbu, sf, symc or vx.

Preparing a volume for DRL and snapshot operations

To prepare an application volume for dirty region logging (DRL) and instant

snapshot operations, a data change object (DCO) and DCO volume must be

associated with the volume.

The procedure in this section describes how to add a version 20 DCO and DCO

volume to an application volume that you previously created in a disk group with

a version number of 110 or greater. If you are creating a new volume in a disk

group with a version number of 110 or greater, you can specify the co-creation of

a DCO and DCO volume and enabling of DRL.

See “Creating a volume for use with snapshots and DRL” on page 75.

See “Adding logs to a volume” on page 89.

You may need an additional license to use the DRL and FastResync features.
