started.
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...
Adding any necessary PowerHA SystemMirror entries to /etc/inittab and /etc/rc.net for IPAT on node hisserver1.

5. 双机的基本操作
5.1. 双机的启动
Smitty clstart
5.2. 双机的停止
Smitty clstop
5.3. 双机状态的查看
/usr/es/sbin/cluster/utilities/clshowsrv -v
5.4. 保存snapshot
/usr/es/sbin/cluster/utilities/clsnapshot -c -i -n'haconf_20131126'
把.info、.odm下载到本地保存一份
快照存储路径：/usr/es/sbin/cluster/snapshots
