Well, it's actively being developed right now, as always.

EMC CLARiiON active/passive failover support is forthcoming.

No, and as far as I know, it's not going to.
I got technical docs + a CX500 from EMC for developing the CLARiiON
support and am busy with just that (if I wasn't writing this mail ;-).
The commandline tools have already been merged upstream, so if you use
sg3_utils, you'll find that sg_inq is able to decode the EMC-specific
Unit Path Report Page and that you can manually switch
Service-Processors for a LUN using the sg_emc_trespass command.
Alasdair and I are ping-ponging patches for the dm-mpath.c, and I think
we should have it done fairly soon...
Sincerely,
Lars Marowsky-Brée <lmb@suse.de>
