Check the multipath status.
Check that all the Storage Repositories that are created in XenServer have multiple paths.
(1)
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
3600000e00d0000000001000000720000 dm-0 FUJITSU,ETERNUS_DXL
[size=10G ][features=1 queue_if_no_path][hwhandler=0 ]
