Remove private LUNs OR resetting to factory

Hello,

we have an old Clariion SAN (CX4-120) that we'd really like to repurpose for test storage, but without a support contract, it seems that a DIY refresh has some challenges. On the bright side, I can get into the Unisphere interface, the service manager, and the http://<ipaddress>/setup page. Also, connectivity is good on our network. On the downside, we lost a whole storage group due to a failed DAE. I also cannot have the UI accept my deleting the old Private LUNs / Pool, nor can I get into the RemotelyAnywhere desktop. I do have the Navisphere CLI installed on a remote machine though. Could someone point me in the direction of what I could do to either

+make the Clariion forget these LUNs & associated pool (they currently show as private LUNs and while I can rt-click -> delete them in the UI, they don't go away)

+reset the Clariion's drive layout to factory - I am not seeing any good references for that.

Huge thanks from Milwaukee!

Do you have a powerlink login for dell?  Can you access the manual form there?

From what I was just told, you need to access the data erasure kit from dell via the powerlink website... That's all the info I was given.  Sorry.  I hope that helps!

I do have a Powerlink account. I am seeing a lot of documentation, but not an admin guide if that is what you mean. Which document do you mean in particular?
There's apparently a data erasure kit (series of applications) for emc clariion sans. I'm told you need to acquire it in order to refresh.
OK, I'm thinking that is the nuclear option. I might try poking around with naviseccli to see what I can remove there. I am guessing that this does a better job than the GUI at these kinds of operations.

Thanks for checking on that for me. Much obliged!
I was able to run naviseccli and  attempt a lun destroy (which doesn't error out, but goes right back to the prompt). The luns remain, even when I run the command on both SPs. If that helps any! I think any helpful commands would be most welcome!

And this looks helpful.

Make sure to copy and paste out any helpful info in there for anyone following this thread in the future.

1. Open Navisphere running on the CX700
2. Went into Engineering mode
3. Right clicked storage array and chose "SnapView", then "Clone Feature Properties".
4. In the Clone Feature Properties dialog box, selected the LUNs from the "Clone Private LUNs" text box.
5. Clicked the "Remove" button for each of them.
6. Clicked "OK"
7. Clicked "Yes" on the confirmation window, at which point they became standard LUNs.
8. Deleted the LUNs!
 
And just in time for the weekend too!
 
Dynamox, thanks for your help. You definitely set me in the right direction!
Thanks - no dice though. I  thought maybe this info might be helpful:

I have posted a side thread at the EMC community forum. So far the conclusion there is that it's time for EMC engineers, so I'm guessing it is time for the nuclear option. Can't find a data erasure kit though, nor any  good instructions on the topic. Anyone with thoughts on that? Or how to deal with offline LUNs?
I also sense that getting to the SP desktop via Remotely Anywhere would get me some good info. Is it possible that anyone could point me in the direction of how to reset a password there?

Nice work.  It would be awesome to hear the final outcome/procedure.
Sorry I had not updated this - EMC shot that tech's statement down, saying that we needed a support contract or paid ticket to get the image file. Makes you think you don't really own it. Will close this question now.
This solution doesn't fix the issue, because there is no DIY fix. The solution is to call EMC and have them do it - they hold their keys tightly.
