If the root volume of a virtual server becomes unavailable, you can use the volume make-vsroot command to promote another of the virtual server's volumes to be the virtual server's root. The command renames the volume as root_virtual_server_name. For instance, if you run this command on a volume named mirror_root_vs0 that is located on a virtual server named vs0, the volume is made the root volume of the virtual server and given the name root_vs0. The command requires the advanced privilege level or higher.
After running the command, unmount all volumes that were mounted below the previous root volume and remount them below the new root volume.
The following example makes a volume named backup_vs1 the root volume of a virtual server named vs1. The command renames the volume to root_vs1.
node::>set -priv advancednode:*>volume make-vsroot -vserver vs1 -volume backup_vs1
