Bug 639028

While testing this version of the lpfc driver using dt over the weekend, 2/4 dt processes stopped without any indication why.  The log files were simply truncated in the middle of messages being written to them.  There was nothing in /var/log/messages at the time the dt log files stopped getting updated.

Host is a dl585-g5

Emulex adapter is Emulex Corporation Saturn-X: LightPulse Fibre Channel Host Adapter (rev 03)

[root@cornucopia host0]# cat fwrev
2.00N9 (U3D2.00N9), sli-3

Vaios,

Should I update the firmware image?

Thanks, Rob

I would think you are using the LPe1205 mezz cards, is that correct?

For the Saturn HBAs you should be using the latest released 2.00a3 version.  Version 2.00N9 was an OEM early evaluation build.

-Vaios-

I changed the firmware as you suggested, changed lpfc_use_msi=2, and restarted the test yesterday.  Similar result occurred.  I don't know if this occurs with the previous rev of the driver but can try that today.

Cleared out some leftover disk state that was tripping up selinux.  Previous problem is unrelated to lpfc driver update.

After comparing this patchset to lpfc w/ posted updates on linux-scsi 8.3.17, I noticed some differences between this patch set and upstream driver.

Please ensure that all applicable bug fixes are posted upstream as well if they haven't been already.  I haven't had a chance to see if any of the missing functionality is in the latest lpfc posting on linux-scsi (8.3.18).

I will be posting this internally assuming Emulex has or will synchronize this patchset w/ upstream.

Missing upstream:
