[ RHEL 5.3 ]System hangs intermittently during iSCSI HBA configuration with inbox driver.
Last modified: 2009-06-20 04:09:33 EDT
Description of problem:
On RHEL5U2 machine, I am using inbox iSCSI HBA driver. During iSCSI HBA configuration using iscli, kernel panics intermittently with following error.
RIP [<ffffffff991307d8>] :qisioctl:qla4xxx_ioctl+0x249/0x12d5
<0>Kernel Panic - not syncing: Fatal exception
Version-Release number of selected component (if applicable):
OS : RHEL5U2
iSCSI HBA : QLA4052C
module : qla4xxx version 5.01.00-k8_rhel5.2-01
iscli version 1.1.00-13
Steps to Reproduce:
1.Configure HBA using iscli.
2.Add new iscsi target.
4.See lun informatin
Host panics intermittently.
Host should not panic.
Once host paniced during configuration, after every next reboot host kernel panics.
Can you confirm that you are using rhel 5.2. Do you observe the same behavior
with the latest rhel 5.3 snapshot?
Can you also please include the test from the system log?
Yes, I have seen this issue with RHEL5.2 GA and RHEL5.3 Snapshot.
Would you mind giving me some more data points.
1. What is the version of the firmware on QLA4052C ?
2. After Step 1. in the 4 steps you mentioned above, what is the target configuration ? I mean can I get a list of targets configured.
3. Also is it possible to test it with a debug version of the ioctl module (qisioctl.ko)(I can provide that).
BIOS version : 1.14
Firmware version : v188.8.131.52
I saved configuration after configuring 10.72.199.94 and 10.72.199.71 as a target. After saving configuration I was not able to see scsi devices in /proc/scsi/scsi, so I reloaded qla4xxx driver. During driver reload kernel paniced. Now after every reboot system is getting kernel panic.
Yes, Please provide me with debug version of ioctl module.
Created attachment 324247 [details]
ioctl module with debug enabled
enclosed is the ioctl module. Please untar it and run ./build.sh to build the ioctl module. Unload the previous ioctl module using "rmmod qisioctl" and install the new one "insmod <path>/qisioctl.ko"
Netapp - any status with the suggested ioctl module from David?
Sorry for the delay.
After some basic testing, I found that this new qisioctl driver is working fine with R5U3(Snapshot4) inbox driver. I didn't see kernel panic.
