Unable to provision Celerra storage?

This one really made no sense to me at first.  I was attempting to create a new file storage pool on our NS960 Celerra.  Upon launching the disk provisioning wizard, it would pause for a minute and then give the following error:

“ERROR: Unable to continue provisioning.  click for details”

It was strange because I have plenty of disks that could be used for provisioning.  Why wasn’t it working?

Here is the detailed error message:

Message Details:

Message: Unable to continue provisioning

Full Description:  Not able to fetch disk information. n Command Failed, error code: 1, output: errormessage:string=”Timeout (60 seconds) waiting for state SS_DISKS_LOADED”

Recommended Action: No recommended action is available. Go to http://powerlink.EMC.com for more information.

Event Code: 15301214354

As a workaround and to test the issue, I used 8 spare SATA drives and created a new raid group, with one large LUN using all of the space.  I added it to the Celerra storage group and rescanned the SAN for storage.

The following error popped up:

Brief Description:  Invalid credentials for the storage array APM01034413494. 
Full Description:  The FLARE version on this storage array requires secure communication. Saved credentials are found, but authentication failed. The Control Station does not have valid credentials. 
Recommended Action:  Set the credentials by running the “nas_storage -modify <backend_name> -security” command. 
Message ID:  13422231564 

Well, how about that.  An error message that actually gives you the command to resolve the problem. 🙂  As it turns out, one of our other SAN administrators had changed the password for the system account.  Running nas_storage -modify id=<xx> -security resolved the problem.

(Note: You can get the ID number by running nas_storage -list)
