Description Naveen Reddy 2008-11-11 23:59:07 EST
Description of problem: Paths remain offline on a RHEL 5.3 host with Emulex FC adapters even after reinstating them.

Version-Release number of selected component (if applicable):
OS - RHEL5U3 GASnapshot1
kernel - 2.6.18-121.el5
Emulex HBA - LPe11002-M4
Emulex driver version -
Emulex firmware version - 2.80A4

How reproducible:

Steps to Reproduce:
1. Map a LUN to RHEL5.3 FC host with Emulex HBA.
2. Verify that all the primary paths and secondary paths to LUN are online.
3. Make the primary paths down
4. Restore the primary paths
5. The primary paths still remain offline.
Actual results:
Paths are remaining offline though they are reinstated.

Expected results:
Paths should become online once the paths are reinstated.

Naveen - I know there is a newer Emulex driver in kernel-2.6.18-122.el5 which you can download here: http://people.redhat.com/dzickus/el5

* Changed version number to

or just wait for the Snapshot 2 ISOs.
Comment 4 Tom Coughlan 2008-11-12 10:16:55 EST
Or even better, try a test with 5.3 with the lpfc taken from 5.2. This will help to isolate the cause.

The last driver patch that was submitted on 11/7 for RHEL5.3 inclusion is Please see Bugzilla 470610--"Update lpfc to version".

We would like you to verify the issue w/ this latest driver.

If this issue is reproducible with the driver, could you please provide us the following information:

- How do you bring the path down and up?
- Are scsi devices going to offline state?
- Reproduce this issue with loading the lpfc driver w/ driver parameter lpfc_log_verbose=67 and send us the log file.

I have tried this on latest RHLE5.3 snapshot(snapshot 2) which has lpfc driver version Paths are becoming online once they are reinstated. 

So, this issue in not reproducible with newer lpfc driver(

Thank you
Comment 7 laurie barry 2008-11-14 10:19:42 EST
Thank you Naveen.

Should we consider then this issue closed as fixed w/ the latest driver rev?

Comment 8 Naveen Reddy 2008-11-16 23:25:43 EST
Since this issue is not seen with newer lpfc driver version, it can be closed.

Thank you
