Limitations related to commands in a non-SSH environment
Some commands work only when passwordless SSH is configured for the root user. If the /opt/VRTSnas/con/communication.conf file exists then, CommunicationType key is set to SSH.
For example:
# cat /opt/VRTSnas/conf/communication.conf
{
"WorkingVersion": "1",
"Version": "1",
"CommunicationType": "SSH"
}The following commands work only when passwordless SSH communication is enabled for the root user:
Backup> install
Cluster> addnode
Cluster> delnode
Cluster> reboot
Cluster> shutdown
FTP> logupload
License> add
All Replication> commands
Report> exportevents
Report> snmp exportmib
Storage> fencing on (for majority-based fencing)
Storage> fencing off (for majority-based fencing)
System> config import
