Before configuring VxVM and VCS disk groups for campus clusters using Veritas InfoScale Operations Manager, you must remove the site tag from the disk group or cluster, as well as remove any tagging set by Veritas InfoScale Operations Manager.

See the Veritas InfoScale Operations Manager User guide for more information on using Multi Site Management in Veritas InfoScale Operations Manager to manage campus clusters across Storage Foundation and Cluster Server objects.

To remove VxVM site tag information

Determine which site a host belongs to, and execute the following command on each host:
```
# vxdctl list | grep siteid
```
Remove the defined site name from each host:
```
# vxdctl [-F] unset site
```
The -F option is required if any imported disk groups are registered to the site.
Optionally, turn off auto-tagging on the disk group:
```
# vxdg -g diskgroup set autotagging=off
```
Verify if site consistency has been enabled for the disk group:
```
# vxdg list diskgroup | grep siteconsistent
```
Turn off the site consistency requirement for the disk group:
```
# vxdg -g diskgroup set siteconsistent=off
```
Identify the site record for each site with the disk group:
```
# vxprint -g diskgroup | grep ^SR
```
Unregister the site record for each site with the disk group:
```
# vxdg -g diskgroup rmsite sitename
```
List the site tags for the disk group:
```
# vxdg listtag [diskgroup]
```

Remove the site tag from the disk group:

# vxdg [-g diskgroup] rmtag [encl:enclosure] site=sitename

Check which disks or enclosures are registered to the site:
```
# vxdisk [-g diskgroup] listtag
```

Remove the site tag from the disk or enclosure:

# vxdisk rmtag site=sitename disk|encl:enclosure

To remove VCS site tag information

Make the cluster configuration writable.
```
# haconf -makerw
```
List the site tagging information on the cluster.
```
# hasite -list
```

Remove the site tagging information from the cluster.

# hasite -modify sitename SystemList -delete -keys

# hasite -delete sitename

Dump the configuration.
```
# haconf -dump -makero
```
