To verify SSH connectivity in a NSP DR cluster
Purpose
Perform the following procedure to verify that the standby nsp-file-service-app pod can SSH to the primary nspos pod.
Steps

2 |
Enter the following to attempt an SSH connection to the primary nspos pod: # ssh -i /opt/nsp/apps/nsp-file-service-app/nspSSHcerts/hostcert -p 8566 -o StrictHostKeyChecking=no address ↵ where address is the NSP cluster advertised address of the active data cluster If the command returns an error message, the SSH connection attempt has failed. |
