Damned Dell

Did you know that you can't mix Ultra 160 EMM cards with Ultra 320 EMM cards?

We have a 220s with four ultra 160 disks and an ultra 160 EMM card. We said to Dell, "we want to upgrade it, put new disks in, and a new EMM so that we can split it between two different servers". So they sold us 7 ultra 320 disks and an ultra 320 EMM. Apparently nobody bothered to check whether 160 and 320 EMMS will work together. Well according to the documentation they don't.

So now we either need to source a 160 EMM, or upgrade the old one to a 320 and hope it all works.

yay.
