Making an existing disk group site consistent
To make an existing disk group site consistent
1 Ensure that the disk group is updated to at least version 140, by running the
vxdg upgrade command on it:
# vxdg upgrade diskgroup
2 On each host that can access the disk group, define the site name:
# vxdctl set site= sitename
3 Tag all the disks in the disk group with the appropriate site name:
# vxdisk [-g diskgroup ] settag disk site= sitename
4 Register a site record for each site with the disk group:
# vxdg -g diskgroup -f addsite sitename
Note: As a side effect of this command, any volumes with unsupported
configurations (for example, RAID-5 volumes) or with an incorrect layout
(not mirrored across the sites) have the allsites=off attribute set on
them.
5 Turn on site consistency for the disk group:
# vxdg -g diskgroup set siteconsistent=on
6 If required, use the vxassist transform commands to convert any
unsupported volumes to a supported layout such as mirror or mirror-
stripe. Specify the siteconsistent=on attribute to ensure that the
plexes are mirrored across the sites.
