Remove Clariion storage system from Celerra
I don't mean physically. The Clariion was unzoned before deleting disks and such. The filesystems have been removed, but the rest of the cleanup needs to take place. And yes, I know the zoning shoul've come last. I wasn't involved in the beginning, but it's suddenly my task. The Clariion has gone through the erasure process and EMC has removed the cable that let the control station talk to the Clariion, which is causing the Celerra to record hourly errors that it is unable to ping SPA/SPB.
My question is, what procees should I follow to gracefully cleanup the Clariion config from the Celerra? Delete disks-delete pool? We only have symm back-ends now, should I remove the naviagent? Or comment out the SP's from /etc/hosts?
I know I have a lot of questions, any help will be appreciated.

Even that procedure would still have the Clariion configured as back-end storage to the gateway.
Please work with your EMC customer service or PS to get this cleaned up.

Thanks Rainer - That's what I figured, since I can't find anything on PW regarding this. I'm sure they don't want customers ruining their Celerra's. I'll go ahead and follow up with our SAM.

Because the backend is gone, it will require manual database editing to remove the storage system. You can try checking nas_storage to see if it is still there, and you can try nas_storage -delete to try to remove it, but that will likely fail because the storage system can't be contacted.
Similarly, you can try nas_disk -delete to delete the unused disks which are no longer present, but that too will likely fail in the same way.
