How to add an DAE to a Clariion CX4-480
Hello everybody,
we run a Clariion CX4-480 with one DAE with EFD's (SSDs), and 4 more with FC-Disks.
We just got 2 new DAEs one with SATA 2TB drives, one with FC drives.
I am aware of the fact that EMC says these must be installed by a EMC-trained technician and I am not going to do that myself (void warranty and be responsible for any desaster that may result), but:
The people sent to us at other cases by our supplier were not always ...uhm...giving the impression of having done all a lot of times which they did at our stuff.
As we have our service contract with that supplier (I can't change that) and I am a technician who likes to know how things work, I would really be grateful if somebody could give me (at least) an overwiew of how to (hot-)add the 2 DAEs while the CX is in service.
Note:
I already have read Dave Z's great docs and posts here in the forum (about will SATA and FC on the same BUS /slowdown?, etc..) it is not about which DAE to which BUS but more like the steps to be accomplished.
We got the DAEs, the BUS cables and 5 CDs (havent looked at them by now, so the purpose is not clear, but will do that).
Thanks in advantage and kind regards
Mike

Moreover, we do have a Procedure Generator available on powerlink which now redirects to http://www.emc.com/clariionsupport
I am not sure it has a procedure to add a DAE or not as some how I am not able to get the CPG page but there are other procedures which will help you in future.

Hello Dynamox and AnkitM, thanks a lot for your assistance. Had a look on the USM > add hardware wizard. The whole procedure looks quite easy (even easier than to add a shelf to our old HP MSA1500 storage). Funny that EMC requires a certified technician on-site in order to keep warranty.... But anyway, I will have a guy from our supplier here when doing it and keep my warranty and have him responsible for any issue caused by adding the DAE- better safe than sorry. I feel much better now, knowing the procedure myself and am really happy with your help. Thanks again and kind regards Mike

The procedure is indeed quite easy until you face a problem adding a DAE!

Encountered it only once..... I tried to add a 2Gb DAE to a 4Gb BE and ofcourse it didn't work. I thought we had a problem there and I was trying to troubleshoot the thing. Took me a day or so to find out I accidently took the wrong DAE from our storage supply room. The correct 4Gb DAE was still sitting in a box waiting for me to unload it
. Nothing did go wrong by the way, the CX4 simply didn't recognise the new but wrong DAE.
(I'm working with EMC since 2004)

Lucky you or may be your understanding with CLARiiON Hardware must be real good!
If only, installing DAE was always with out a problem we wouldn't get calls for assistance from Field Support!

It's not that I add new DAEs every day or even every week, but in the last 8 years I've come accross a few problems. But I must say that I'm very pleased with the quality of hardware that EMC provides. Almost never do we run into severe problems which we can't fix ourselves.
