Execute the "mpathutil list" command and check that all the Storage Repositories that were cre-
ated in
Example:
$ mpathutil list
3600000e00d0000000001000000720000
3600000e00d0000000001000000730000
3600000e00d0000000001000000740000
3600000e00d0000000001000000320000
3600000e00d0000000001000000330000
(2)
Execute the "mpathutil status" command to check the following items.
Example:
When the ETERNUS DX80 S2 is connected in a two-path configuration
The multipath consists of the block device names "sdb"
and "sdn. "3600000e00d0000000001000000720000"
is created.
$ mpathutil status
3600000e00d0000000001000000720000 dm-0 FUJITSU,ETERNUS_DXL
[size=20G ][features=1 queue_if_no_path][hwhandler=0 ]
\_ round-robin 0 [prio=50][active]
\_ 1:0:0:0 sdb 8:16 [active][ready]
\_ round-robin 0 [prio=10][enabled]
\_ 4:0:0:0 sdn 8:208 [active][ready]
Example:
When the ETERNUS DX80 S2 is connected in a four-path configuration
The multipath consists of a path group with the block devices "sdb" and "sdl" and a path
group with the block devices "sdq" and "sdg". "3600000e00d0000000001000000720000" is
created.
$ mpathutil status
