Solved!
Go to SolutionNeed to remove DAE on CX4-480 flare code 4.30.x
This is the last DAE on the bus...no drives on it...just the DAE (bus1 enclosure2) is attached to Bus0 enclosure 2. Need to remove it so that we can use the DAE on another frame.
I'm concerning about steps to remove the LCC cables. I assume the Management Console needs to be rebooted afterwords. I was hoping USM would walk me thru but it doesn't.
Any docs/explantions would be great.
Thanks

USM doesn’t allow you to remove DAEs….only add them.

You can download the CLARiiON Procedure Generator from Powerlink which would give you step by step instructions.
Moreover, I reckon in order to remove a blank DAE you can run Install/Uninstall Hardware wizard from USM and that would be it!

Technically this is possible, I don’t think the procedure is documented and you will want to make sure EMC support is engaged.

isn't there a procedure to remove DAEs that are not at the end of the loop, one LCC at a time ?

Oh Sorry, my bad. I just checked CPG, there is a procedure there well you can follow that if you like but basically its just I initially thought Just remove it!
Then restart the management server to remove the ghost entries in Navisphere/Unisphere GUI.

I have a customer that needed to do it on a VNX and at first support said it couldn’t be done, then they later “created the procedure and tested it in the lab” so my impression is that it’s not in even the internal CPG, nor is it in any public documentation. So that’s why I suggest getting with support if you actually need to remove a DAE in the middle of a loop.

that procedure is not documented for customers or for EMC support ?

The procedure is not mentioned seperately in CPG. However, its there when you run Uninstall a DAE/DAE2-ATA/DAE2P/DAE3P enclosure from an active storage system CPG.
Only thing you need to keep in mind is when you remove the HSSDC Cable from the LCC A of the Encl you want to remove you would need to plug the lower encl's Cable to the one above it and follow the same for LCC B.
I will post a detailed post with a diagram soon. (Sun or Monday - gtg)

IF…
1.) The DAE is at the end of the loop
2.) The DAE has no installed disks
Then you can simply unplug the LCC cables from that DAE and remove it. You will need to log in to the setup page (http://spip/setup) on each SP and restart the management server on each SP in order to clear the faults.
Be sure you have NO faults on the array before you start this process.
