Hi
I've recently added an EMC CX3-80 ... And provisioned volumes to my
RHEL4-4 running with multipath tools v4.7.
I've added the recommend settings by EMC for the CX to the
multipath.conf file (below) but I am seeing the following errors;
devices {
## Device attributes requirements for EMC Symmetrix
## are part of the default definitions and do not require separate
## definition.
## Device attributes for EMC CLARiiON

}

[root@ldm1066 log]# multipath -F
I'm thinking this is a configuration issue on the CX ...
Any comments / suggestions?
Thanks,
Paul
