VMesxi 3.5 Lun Mapping Issue

[staygreen]

Hi, All

I have one vmesxi 3.5 with two EMulex LP10000 HBA installed for connecting one EXC CX300 storage via two EMC switches.

~ # esxcfg-vmhbadevs -a

vmhba1:0:0 /vmfs/devices/disks/vmhba1:0:0:0

vmhba1:1:0 /vmfs/devices/disks/vmhba1:1:0:0

vmhba2:0:0 /vmfs/devices/disks/vml.0200000000600601608d311900d075d16a6baedf11524149442031

I List all vmhba mappingas above. The Lun on vmhba2:0:0 is as follows.

/vmfs/devices/disks/vml.0200000000600601608d311900d075d16a6baedf11524149442031

==>

0200000000-- 600601608d311900d075d16a6baedf11--524149442031

I found 600601608d311900d075d16a6baedf11 is EMC LUN UUID.

My question is what 0200000000 and 524149442031 mean.
