Yes - the device-mapper tables looks like:
vserv81:/root # dmsetup table RAID_A-test.root
0 20971520 linear 253:6 384
(this is one the FS which causes the crash when mounting via ext3)
And 253:6 is the multipath device:
vserv81:/root # dmsetup table 3600d023100065bef0000000009f337c0
0 15626018816 multipath 0 0 2 1 round-robin 0 1 1 8:16 1000 round-robin 0 1 1 8:48 1000
And 8:16, 8:48 are two qla2xxx FC ports.
Cheers,
Christophe
