Hi all

I have installed SLES 11 SP3 with kernel version 3.0.76-0.11-default on my host. I have two paths connected between my host and SAN storage.
If I run the command(multipath -ll) repeatedly I see that paths alternate between failed and active, inspite of the fact that my storage is up and running normally. I have installed Emulex HBA cards and I am working with the inbox drivers as I did not find any updated drivers from emulex.com for SLES 11 SP3.

The paths that go in fail state are random, no fixed pattern. A sample can be seen as:

mpathg (200169712241d001c) dm-6 XYZ ,DISK ARRAY
size=2.0G features='0' hwhandler='1 alua' wp=rw
|-+- policy='service-time 0' prio=10 status=enabled
| `- 1:0:0:4 sde 8:64 failed ready running
`-+- policy='service-time 0' prio=50 status=active
`- 2:0:0:4 sdr 65:16 active ready running


Sometimes even both paths to a LUN go in failed state as:

mpathf (200169712241d001b) dm-5 XYZ ,DISK ARRAY
size=2.0G features='0' hwhandler='1 alua' wp=rw
|-+- policy='service-time 0' prio=90 status=enabled
| `- 2:0:0:3 sdq 65:0 failed ready running
`-+- policy='service-time 0' prio=50 status=enabled
`- 1:0:0:3 sdd 8:48 failed ready running


However I am not facing any such issue with SLES 11 SP2. Please help!
