Have you tried rebooting?

Your Clariion storage processor management server?

Here’s the scenario, you have a host in your Clariion config you no longer want. Maybe it’s retired or you virtualized it or maybe you just plain fat fingered the name when you manually registered the darn thing. Regardless, it’s there and you want it gone.

Of course you have already done the following:

1. Removed the Host from its storage group.

2. De-registered all associated HBAs

But that darn host won’t go away in the Host list. The problem is that each Storage Processor needs to rescan the Fabric. To do this you have to Reboot (OK really its restart) each SP’s management servers. Below are the steps to do so.

You must do the following on both SPA and SPB.

Log into SP setup interface

http://SP IP address/setup

Enter your login Credentials (nas admin should work)

Scroll down until you see the following and click "Restart Management Server".

Click the "yes" radio button and then "submit"

That’s it! You should be good to go. Logout and log back in to any Unisphere or Navisphere interface you may have been in and check you host list.

The concept of rebooting or restarting some service seems to be a theme that comes up over and over in an IT Admin’s career. I believe the concept of rebooting one’s own internal system is something that we as organic machines don’t do often enough. Too many times we get stuck in our ways closing our minds to new possibilities. Whether it’s with your job or personal life the next time you seem to get stuck on a process or feel you are in a never ending loop of negative feedback, ask yourself.
