Restoring One or More Nodes in a Cluster
142
To update the cluster configuration:
1. Delete the cluster node:
# clu_delete_member -m member#
where member# is the number of the cluster node.
2. Remove the node’s boot partition domain:
# rmfdmn rootmember#_domain
3. Add the computer back into the cluster using the clu_add_member
command. For more information about adding a cluster node, refer to the
TruCluster documentation.
Task 5: Recover the Node-Specific Data
Once the cluster node has been added and configured, recover its
node-specific data. Node-specific data includes information such as node
licenses and volume definitions that would be difficult and time-consuming to
replace unless they are recovered.
Note: Perform this task on the down node:
To recover the node-specific data:
1. Boot the cluster node.
# boot -file genvmunix dkc2
where dkc2 is the cluster disk.
2. Use the NetWorker recover command in interactive mode to recover the
cluster node data, as shown in the following example.
Note: The force option is used in this step so that the recovered files
overwrite the existing files.
# recover -c cluster_default_alias
recover> add /usr/cluster/members/membermember#
recover> add /var/cluster/members/membermember#
recover> add /cluster/members/membermember#/etc
recover> cd /cluster/members/membermember#
recover> delete ddr*
recover> delete gen*
recover> delete dfsl*
