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.
