If this warning persists, the administrator should perform the following steps to enable grace periods on hisserver1 at the next planned downtime:

1. stopsrc -s nfsd

2. smitty nfsgrcperiod 3. startsrc -s nfsd

WARNING: Node hisserver2 has cluster.es.nfs.rte installed however grace periods are not fully enabled on this node. Grace periods must be enabled before NFSv4 stable storage can be used.

PowerHA SystemMirror will attempt to fix this opportunistically when acquiring NFS resources on this node however the change won't take effect until the next time that nfsd is started.

If this warning persists, the administrator should perform the following steps to enable grace periods on hisserver2 at the next planned downtime:

1. stopsrc -s nfsd

2. smitty nfsgrcperiod 3. startsrc -s nfsd

Remember to redo automatic error notification if configuration has changed. Committing any changes, as required, to all available nodes...
