From a list of nids for a remote node, show which interface communication
will take place on.
.TP
-.BI replace_nids " <devicename> <nid1>[,nid2,nid3 ...]"
+.BI replace_nids " <devicename> <nid1>[,nid2,nid3:nid4,nid5:nid6 ...]"
Replace the LNET Network Identifiers for a given device,
as when the server's IP address has changed.
This command must be run on the MGS node.
mount -t lustre <MDT partition> -o nosvc <mount point>
Note the replace_nids command skips any invalidated records in the configuration log.
The previous log is backed up with the suffix '.bak'.
+Failover nids must be passed after ':' symbol. More then
+one failover can be set (every failover nids after ':' symbol).
