How to fix IBM Storwize V7000 Unified authentication errors

If the IP address for IBM® Storwize® V7000 Unified is not configured correctly on SAN Volume Controller, you get an authentication error when you add the storage system in IBM Spectrum® Control.

Problem

You can add IBM Storwize V7000 Unified on a SAN Volume Controller to IBM Spectrum Control as either a file storage system, or block storage system, or both. However, if you add a block storage system IP address for a file storage system, or vice versa, an authentication error occurs.

Action

To solve the issue, complete these steps:
  1. Get the IP address of IBM Storwize V7000 Unified storage system from the Storwize V7000 Unified Management GUI.
  2. Get the IP address for the Storwize V7000 Unified storage system registered on SAN Volume Controller by using the following command on a command line of SAN Volume Controller. svcinfo lscluster -devicename
  3. Update the IP address on SAN Volume Controller with the IP address from step 1 by using the following command: chsystemip -clusterip <IP address>
  4. Retry the connection on IBM Spectrum Control.
