Question
When dsmmigfs q -d is issued what should the NodeID, Owner Node, Preferred Node be for each cluster node.
Cause
# dsmmigfs q -d (from Node2 in the cluster)
...
The local node has Node ID: 2
The failover environment is active on the local node.
File System Name: /GPFS0
High Threshold: 90
Low Threshold: 70
Premig Percentage: 20
Quota: 999999999999999
Stub Size: 0
Server Name: SERVER_A
Max Candidates: 100
Min Partial Rec Size: 0
Min Stream File Size: 0
MinMigFileSize: 0
Preferred Node: Node1 Node ID: 1
Owner Node: Node1 Node ID: 1
Source Nodes: Node2
Answer
The NodeID, Owner Node, Preferred Node settings are dependent on the node where the dsmmigfs is issued and whether a failover has occurred.
When there is a cluster of 2 nodes, lets assume they are node1 and node2 and node 1 is the owner.
Initial configuration should show:
Node1 Node2
Node ID 1 2
Preferred Node 1 1
Owner Node 1 1
If a failover has occured the 'dsmmigfs takeover' command would be issued to change the owner node to node 2
Node1 Node2
Node ID 1 2
Preferred Node 1 1
Owner Node 1 2
