We have a ton of these log messages now.
>From the last about 2 hours:

580x multipathd: 3600601f4a20c000099dc229956b0d711: switch to path group #1
714x multipathd: 3600601f4a20c000096dc229956b0d711: switch to path group #1
714x multipathd: 3600601f2a20c0000fb13caa656b0d711: switch to path group #1
  45x kernel: device-mapper: dm-emc: emc_pg_init: sending switch-over command

It happens only for these 3 of 8 luns.

Kernel is 2.6.13.4, devmapper 1.01, latest multipath-tools from git, evms 
2.5.3

zeus-1:/# cat /etc/multipath.conf
defaults {
        failback                                immediate
}


Since we had a lot of trouble with our CX400 (Hardware problems, but they're 
supposed to be fixed) I'm wondering what these messages mean, and if we still 
have hardware/software bugs somewhere.

Any ideas?
Thanks for your help!


Bernd
