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 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/, 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).

About the ServiceNav Box

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.
