Setting tags on volumes
Volume tags are used to implement the Dynamic Storage Tiering feature of the
Storage Foundation software. For more information about this feature, see the
Veritas File System Administrator’s Guide.
You can use the following forms of the
vxassist command to set a named tag
and optional tag value on a volume, to replace a tag, and to remove a tag from a
volume:
# 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 this command:
# vxassist [-g diskgroup ] listtag volume
To list the volumes that have a specified tag name, use this 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 here:
# 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, it is recommended that tag
names do not start with any of the following strings: asl, be, isp, nbu, sf,
symc or vx.
