To configure VxVM diskgroups for campus cluster configuration
vxdctl set site=sitename
The site name is stored in the /etc/vx/volboot file. Use the following command to display the site names:
vxdctl list | grep siteid
vxdisk settag site=sitename encl:enclosure
To tag specific disks, use the following command:
vxdisk settag site=sitename disk
vxdisk listtag
vxdg init diskgroup siteA_disk1 siteB_disk2
vxdg -g diskgroup addsite sitename
vxdg -g diskgroup set siteconsistent=on
vxassist -g diskgroup make volume size
With the Site Awareness license installed on all hosts, the volume that you create has the following characteristics by default:
The allsites attribute is set to on; the volumes have at least one plex at each site.
The volumes are automatically mirrored across sites.
The read policy rdpol is set to siteread.
The volumes inherit the site consistency value that is set on the diskgroup.
