Have you tried to boot the os using 6.5 kernel and see any difference ?

Good point.

The previous kernel works ok.

I also have forgotten to say that I use centos plus kernels:

2.6.32-504.el6.centos.plus.x86_64: Does not work 2.6.32-431.29.2.el6.centos.plus.x86_64: OK

OK. That's great. I would try following

1. Boot using working kernel. 2. Verify the associated modules loaded. 3. Boot into new kernel, verify the same sets of modules are loaded or not. 4. Like it said in one of the post below, you can try 'modinfo `hpsa module name*` from newer kernel. If no result found, install the kmod-hpsa package that's matching with the kernel version.

* I am not sure about the exact module name.

5. I would prefer a reboot after kmod package installation.

Cheers,

Hello,

After updating to 6.6 I've lost my connection to my tape library.

Old log file (6.5):

Sep 13 08:17:51 server1 kernel: scsi 1:2:0:0: Sequential-Access HP Ultrium 5-SCSI Z65W PQ: 0 ANSI: 6 Sep 13 08:17:51 server1 kernel: scsi 1:2:0:1: Medium Changer HP 1x8 G2 AUTOLDR 4.20 PQ: 0 ANSI: 5

New log file (6.6):

Oct 28 18:15:06 server1 kernel: scsi1 : hpsa Oct 28 18:15:06 server1 kernel: hpsa 0000:0b:00.0: RAID device c1b3t0l0 added. Oct 28 18:15:06 server1 kernel: hpsa 0000:0b:00.0: Sequential-Access device c1b2t0l0 added.

No sign of 1:2:0:1 after reboot, /dev/changer does not exist.

Do I have to do something special to have the new hpsa driver look for multiple LUN's?

There is a kmod-hpsa .. do you have that installed?

Try 'yum install kmod-hpsa'

It does not look like it will matter .. that is the same version as is in the new kernel it seems. (3.4.4)

Hi,

05:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers (rev 01) 0b:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers (rev 01)

ok. I think, it would be really great if you could share the output of

# lspci -vn | egrep '05:00.0|0b:00.0'

Cheers,

Booted on the old kernel:

05:00.0 0104: 103c:323a (rev 01) 0b:00.0 0104: 103c:323a (rev 01)

Ok, it seems the kernel 2.6.32-504.el6.centos.plus supports the above said hardware and driver hpsa is included in the kernel.

Even I have installed the kmod-hpsa and checked the driver version. Per latest kmod-hpsa-3.4.4_1_RH1-1.el6_5.x86_64 available, the driver version is one lower than module shipped in 2.6.32-504.el6.centos.plus kernel and changelog of kmod doesn't show anything relevant to your issue.

Based on the data extracted, I would say,

* The issue you have encountered is not due to missing driver support. * Enabling scsi logging would be the next step to figure it out the reason why tape is not functioning in latest kernel.

@list, please shoot if any other suggestions .
