lbolt errors

I need help deciphering what device is causling this fault SCSI: Unhandled interrupt -- lbolt: 626, dev: cb004002

I am coming up with c0t4d2? There is no such device am I missing something? Here is a list of my controllers.

Re: lbolt errors

The controllers do not help in this case. The key value here is the "dev: cb004002" from the error. This is the major and minor number of the disk in /dev/rdsk directory listing. The "cb" is 231 and the 004002 is probably disk c0t4d0s2

Re: lbolt errors

Hi David,

Does it mean u dont have any such device in ioscan ?

Can u send me ..

#ioscan -fn

If this is a HDD you can check for read and write errors in cstm, by running the following commands.

#cstm
cstm>map <== check the hardware path of the device which is reporting lbolt, make note of the device number...
cstm>sel dev
cstm>info
cstm>il <== this will give you the complete information about read and write errors...

Any read & write errors replace the disk immediately.

Best Regards,
Prashanth

Re: lbolt errors

Hi David,

Lbolt errors are actually from c0t4d0 which is a tape drive connected to this system C5683A (suspect it should be a C5300 tape array a DAT 40 DDS4 module), suggestion would be to check ..

1. If there was any backup process running when this error reported.
2. Check if cable connected from server to drive
3. Check for stape and scsi patch level
4. If still issue persists get the drive replaced by logging a support ticket with HP.

Best Regards,
Prashanth

Re: lbolt errors

Hi

The device format is: MMBBTLFF

Where : MM = Major number
BB = Bus number
T = Target
L = LUN
FF = Flags

ls -l /dev/rdsk/*|grep 004002

yields the cXtYdZ of the disk device.

Re: lbolt errors

Prashanth.D.S

Help me out with this, I don't get your cstm procedure or your conclusion. Albeit, tape drive's are a very good guess, and c0t4d0 is a very good guess, yet I don't see any backup for this. By your formula I should be looking for c0t4d2 but this doesn't appear.

When I use cstm I don't use inforlog as it is not built for tracking errors the way logtool is.

David, please provide this report:

cstm<<-EOF
runutil logtool
rs
EOF

It's import that you include the start and end time in this report David, Thanks!
