Task 1: Replace the Damaged Hardware
Replace the damaged equipment with the same or similar model equipment as
installed previously. Connect all the equipment as previously connected.
Task 2: Verify Hardware Mappings
Open the SRM console and set the logical mappings for each node’s managed
disks and volumes to their original settings. To help complete this step, use the
information that was recorded from the SRM console prior to the disaster.
Task 3: Install and Configure the Cluster Software
Perform a stand-alone installation of Tru64 on the primary node’s stand-alone
boot drive. This task requires the cluster information that was recorded prior
to the disaster.
To install and configure the software:
1. Install the base operating system and TruCluster package on the primary
node’s stand-alone boot drive. For more information, refer to the
TruCluster installation documentation.
2. Configure the network resources.
3. Verify that the system topology matches what you recorded, and the
device layer is configured the same, as follows:
# hwmgr -view hierarchy
# hwmgr -view devices
4. If the logical disks are enumerated differently than in the original
configuration, manually reapply the original enumeration to the disks.
