Recovering from site failure

If all the hosts and storage fail at a site, use the following commands to reattach the site after it comes back online, and to recover the disk group:

# vxdg -g diskgroup [-o overridessb] reattachsite sitename

# vxrecover -g diskgroup

The -o overridessb option is only required if a serial split-brain condition is indicated, which may happen if the site was brought back up while the private network link was inoperative. This option updates the configuration database on the reattached site with the consistent copies at the other sites.
