Pre-check before restarting the NSD Nodes

Before restarting the NSD Nodes or Quorum Manager Nodes or other critical nodes, do check the following first to ensure the file system is in the right order before restarting.

1. Make sure all three quorum nodes are active.

# mmgetstate -N quorumnodes

*If any machine is not active, do *not* proceed

2. Make sure file system is mounted on machines

# mmlsmount gpfs0

If the file system is not mounted somewhere, we should try to resolve it first.
