运行/usr/sbin/cluster/diag/clconfig -v '-tr'命令出现几个警告信息,求解释,谢谢
WARNING: To prevent the IP stack from being a single-point-of-failure,
HACMP recommends a non-IP network topology in which each node
in the cluster can use non-IP networks to reach all other nodes
in the cluster, either directly or via other nodes. This topology
should be in addition to any configured IP-based networks.
The following node(s) or sets of "non-IP connected" nodes violate
this recommendation:
p720_1
p720_2
It is recommended that these nodes or sets of nodes be inter-connected
via additional non-IP networks, such as RS-232, shared disks for disk
heartbeating, etc.

WARNING: Application monitors are required for detecting application failures
in order for HACMP to recover from them. Application monitors are started
by HACMP when the resource group in which they participate is activated.
The following application(s), shown with their associated resource group,
do not have an application monitor configured:

WARNING: Node p720_1 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.
HACMP 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 p720_1 at the next planned downtime:
1. stopsrc -s nfsd
2. smitty nfsgrcperiod
3. startsrc -s nfsd
WARNING: Node p720_2 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.
HACMP 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 p720_2 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.
Verification has completed normally.
