Hi friends,

I am finding the following error in the syslog.

is it pointing to any critical errors? pls help me.

Thanks In advance.

I think this has to do with your SCSI driver. Suggest you have a look at loading PHKL_30510 SCSI IO Cumulative Patch. Be aware that there is at least one dependancy.

"SCSI: Data Overrun" means that the bus and the device are not syncing.

It's often caused by using the wrong driver.

You can determine the device "dev: cb050000"
cb is 203 in hex which can be associated with the sctl driver.
# ll /dev/* |grep 050000

lbolt is nothing more than system ticks since the system has been up, and can be ignored. It's the events associated with the lbolt that matters.

So check the device and determine if you're using the right driver. Check for the associated patches. If you need further help, what model system, what device (model) is using this device file? Provide the os level also.
# ioscan -fnC tape

bkpsvr:toor-/>ll /dev/* |grep 050000

The device in question is:
autoch 0 0/2/0/1.0.0 schgr CLAIMED DEVICE HP C7200 /dev/rac/c5t0d0


There is no patch for schgr but there are several for 11.11 and SCSI:
PHKL_31234 s700_800 11.11 SCSI Ultra160 Cumulative Patch
PHKL_31134 s700_800 11.11 SCSI IO Cumulative Patch
PHCO_29327 s700_800 11.11 cumulative SAM patch

Are these patches installed?

[Ranjith_5]

Its is not showing any out put when i gave a "swlist -l patch|grep PHKL_31134" same for all the 3 patches mentioned.

Look to see what is installed:
# swlist -l fileset |grep SCSI

[Ranjith_5]

Hi griffin, It gives the following output.

Goto "maintenance and support for hp products" in the itrc site and then look for individual patches. Looks like installing them will resolve your problem.
