Multipath with SuSE SLES9 and MSA 1000: scsi reservation conflict

[jj458]

Hi,

i have heavy problems setting up multipath on a SLES9 system.

With multipath -l all devices show only 1 path and they are failed.

Kernel log shows many messages "reservation conflict":

Feb 7 18:56:59 (none) kernel: scsi0 (0,0,18) : reservation conflict
Feb 7 18:56:59 (none) kernel: SCSI error : <0 0 0 18> return code = 0x18

Feb 7 18:57:29 (none) multipathd: 8:16: reinstated

...

In the attached file you find a configuration summary.

What am I doing wrong?

Shalom,

I card could have gone bad. You may wish to try using ACU 7.55 to boot the system and configure the MSA-1000.

Hi Steven,
I do not think a card has gone bad:
1. from MSA 1000 i see both servers on each on both cards
2. on the second linux server i have the same problem
3. In /proc/scsi/qla2xxx/0 and /proc/scsi/qla2xxx/0 i see both cards and i see the connected MSA
4. hwinfo -scsi shows the MSA on both adapters (Number 80 attached to fibrechannel #76 and number 87 attached to fibrechannel #77):
