EMC – CLARiiON / VNX Disk Addresses

Mat came across this about 9 months ago, and I’d forgotten to post it here. I don’t know when it happened, or whether it’s always been like this, but EMC have apparently used letters to reference disks in VNX and CLARiiON systems for a while now. It looks something like this:

What we can’t work out is what it looks like when you’ve got a 60-disk DAE in play. In any case, I verified that it works with naviseccli on our CX4 arrays.

And here it is but using E instead of 14.
