Hi,
We had received a new EMC storage (Clariion CX4) and the EMC analist has
told us that CentOS aren't on their support list, but RHEL are :)
Well anybody on the list has a CentOS host talking (iSCSI) with an EMC
storage,
preferably using the EMC Powerpath software, and can talk about you experience?
Or I will need to buy some REHL licenses ?
I'll put my hands on it only next week, but I'm trying to get
prepared to do it :)
Thanks in advance,
Antonio.

I feel I must bring something to your attention. There is a huge difference between an "analist"[1] and an "analyst"[2]. Just thought you'd be interested to know... :D [1] http://www.urbandictionary.com/define.php?term=analist [2] http://en.wikipedia.org/wiki/Analyst --Tim

You certainly need some time to see what this is all about (we had a different animal here, it was not iSCSI, it was Fibre Channel with all Brocade bells and whistles :), but it really rocks.

Like others I fully expect it to work just fine(as good as EMC stuff can be expected to work), but will they help you if CentOS is not a supported distribution? Some vendors will go out of their way to give a best effort support for unsupported configurations, others will not. Some understand that CentOS is practically identical to RHEL, others have a hard line drawn that says they won't support it. If whomever your getting support from won't support it if you have a problem then your probably best of getting a supported solution, or building a solution you could support yourself. I would expect EMC to publish docs on how to get device mapper MPIO to work with their systems, for those that have unsupported configurations for powerpath. Oftentimes the vendor's local SE can be a valuable support resource I lean on them a lot more than I lean on the formal support organizations as they often times have a better understanding of the particular customer environment, and the personal relationship inspires them to put an extra effort out to help to keep the customer happy. nate

It will take some configuration, but once done smoother than power path you won't have to rpm -e && rpm -ivh powerpath with each kernel update
