Checking the device-mapper multipath Status and Created Devices

Check the path status using the "multipath -ll" command.
• When both paths are in normal status (This example is for the ETERNUS2000)
The multipath consists of the block device
names "sde" and "sdc". "mpath2" is created.
# multipath -ll
mpath2 (3600000e00d00000000000f7e00010000) dm-1 FUJITSU,E2000
