Multipath Query
Hi,

I am running RHEL6 on a physical node (HP Proliant).
If it normal for the root device to get listed in the "multipath -ll" output? (Listed below as dm-4, HP LOGICAL VOLUME).

i.e.
Code:
asm-data (360a98000424a414b453f443548503644) dm-3 NETAPP,LUN
size=768G features='4 queue_if_no_path pg_init_retries 50 retain_attached_hw_handle' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active
| |- 2:0:0:11 sdc  8:32   active ready running
| `- 3:0:0:11 sdd  8:48   active ready running
`-+- policy='round-robin 0' prio=10 status=enabled
  |- 2:0:1:11 sdq  65:0   active ready running
  `- 3:0:1:11 sdx  65:112 active ready running

mpatha (3600508b1001c5c8ef3f93243d9a1bd41) dm-4 HP,LOGICAL VOLUME

asm-log (360a98000424a414b453f443548503642) dm-0 NETAPP,LUN
size=256G features='3 pg_init_retries 50 retain_attached_hw_handler' hwhandler='0' wp=rw

Thanks,
D.
