Hardware Environment
    Machine type (p650, x235, SF2, etc.): SF2
    Cpu type (Power4, Power5, IA-64, etc.): Power5
    Describe any special hardware you think might be relevant to this problem:

Please provide access information for the machine if it is available.


Is this reproducible?
    If so, how long does it (did it) take to reproduce it?
    Describe the steps:

Boot system with storage configured with 8 LUNS per HBA.
Observe that only LUN0 of each storage system is mapped to sg device.

    If not, describe how the bug was encountered:


Is the system (not just the application) hung?
    If so, describe how you determined this: 

Did the system produce an OOPS message on the console?
    If so, copy it here:


Is the system sitting in a debugger right now?
    If so, how long may it stay there?


Additional information:

This bug was not present in 2.6.13-rc7 kernel with 8.0.30 version of Emulex 
lpfc driver.

Created mirror request (id=4806)Novell Bugzilla

This was requested last week, a little delay in getting it mirrored over, but
here it is....

Comment 1 Olaf Hering 2005-10-19 12:58:02 UTC

you could try 2.6.14-rc4-git$latest, its likely already fixed. but we did not move up to 2.6.14 for the next OSS snapshot.
I will try it myself once our console server is back.

Comment 2 Olaf Hering 2005-11-08 12:11:46 UTC

I bootet 2.6.14-rc5 and this one shows all luns. I cant boot 2.6.13 on this RS64 box, so I cant verify if the problem did exist there.
Please retry the current kernel of the day, it is supposed to boot.
reopen this bug on our side if that kernel still doesnt work.
