Hi, I'm trying to create a multipath environment for my server attached to a hp 2012sa msa disk storage device. Where I am struggling is understanding some low level concepts. I've setup the multipath config file, and can see the following enteries: multipath -ll mpath0 (3600c0ff000d7ba4f4575b24a01000000) dm-5 HP,MSA2012sa [size=9.1T][features=1 queue_if_no_path][hwhandler=0][rw] \_ round-robin 0 [prio=50][active] \_ 0:0:0:1 sda 8:0 [active][ready] \_ round-robin 0 [prio=10][enabled] \_ 1:0:0:2 sdb 8:16 [active][ready] cat /proc/partitions shows: 8 0 9767460864 sda 8 16 9767460864 sdb 104 0 71652960 cciss/c0d0 104 1 104391 cciss/c0d0p1 104 2 71545477 cciss/c0d0p2 253 0 5111808 dm-0 253 1 5111808 dm-1 253 2 1015808 dm-2 253 3 5111808 dm-3 253 4 6127616 dm-4 253 5 9767460864 dm-5 sda and sdb are the same, as there is only one disk but two separate paths to it, so it shows up twice under different device mappings. My question now is after restarting mutlipathd, what is the next step? Do I need to use dmsetup, searching the web I still can't understand why I need it. I'm looking to create a logical volume on this disk. Once multipath is working should I only see one entry in /proc/partitions, instead of /dev/sda and /dev/sdb?
