steps to remove DAE

You can follow the steps in the link below.  The Document section of this Forum has many great proceedural documents that can help in daily Clariion administration.

Make sure you follow the steps in the comments at the bottom to clear the fault after removal

On the link Kenn posted, be sure to read his comment below on the link - no SP reboot is necessary.

I am sure some of the EMC folks will look at this post and my question is how do we get that document that is linked above corrected?  Steps 5 & 6 dont need to be in it and i think they confuse people.  Step 7 can probally also be removed.

Maybe someone can remove those steps and also add my comments to clear the fault to it and make is complete...

Open By ID: emc147125 - "Can a CLARiiON disk array enclosure (DAE)  be removed without shutting down array?"

You are only able to remove a CLARiiON DAE without shutting down the CLARiiON under the following circumstances:
There are no active LUNs or RAID groups on the enclosure. (If there were LUNs and RAID groups on the enclosure previously, they must be destroyed/unbound.)
The enclosure is the last enclosure on the Fibre loop. (Due to the daisy chain connection of DAEs, removing a middle enclosure will take higher enclosures offline.)
The enclosure will show as faulted/empty in Navisphere until both SPs are rebooted (usually done consecutively).
Caution! This should be a scheduled activity. It is strongly recommended that EMC Field Support be engaged to disconnect the enclosure because if done incorrectly, the result could be a severe DU/DL situation.

I can speak from experience since i have removed about 10 DAE's in the last 2 months and did not have to reboot the SP's once.  TO clear the fault, you need to restart the "management server"... Also, i think that link you posted is internal to EMC only and is 3 years old.   I cant access it with my partner login.

Thank you for this clarification - it's a pretty huge difference (restarting mgmt server vs restarting both SP's).
