Dismount the Target System Disk Elsewhere
in the Cluster
Before installing OpenVMS on a target drive in an OpenVMS
Cluster, make sure the target system disk is not mounted elsewhere
in the cluster. The target system disk must be dismounted clusterwide
(except on the system from which the installation is being performed)
and must remain so during the installation. For instructions on
dismounting cluster disks, refer to
Preparing Your System for a Rolling Upgrade.
