To monitor a storwize Vx000 array (V3000, V5000, V7000), iYou must create an SSH authentication key, without a passphrase, to connect to the IBM Storwize device with the user nagios. This key should then be integrated into the Storwize array.
About the ServiceNav Box
Connect in SSH console mode with the root user.
Check for the presence of the /home/nagios/.ssh folder, and the : ls -la /home/nagios/.ssh
If it does not exist, create it: mkdir /home/nagios/.ssh
If the user/group is not nagios, change the rights : chown nagios:nagios /home/nagios/.ssh
Switch to nagios user: su nagios
Generate key : ssh-keygen
Keep the default options, do not enter a passphrase. You can see that the id_rsa.pub file is created in the /home/nagios/.ssh directory, and only contains the key on one line.
On your workstation, create a text file containing the contents of /home/nagios/.ssh/id_rsa.pub, on a single line.
On the IBM Storwize array
Create a nagios user and place it in the group Monitor. Assign the previously created key to it (import the text file).

Test by connecting to the bay IBM Storwize : ssh nagios@
If the connection is made without a password prompt, the test is positive. If not, it is likely that the key was incorrectly copied / associated with the nagios user created on the IBM Storwize array, carefully repeat the procedure.
