SCSI Retry lbolt error

nancy rippey — Wed, 17 Apr 2002 13:04:16 GMT

I am receiving the following in my syslog
SCSI: Reset detected -- lbolt: 84694040, bus: 1

In dmesg the
bp-> b_dev is 1f012600

Could someone help me with what device this is pointing to.

Thanks in advance.

hi nancy

Are you using service guard?

1f012600 after 1f .. 012600 which should translate to c1t2d0. Might want to check if that disk is responding to diskinfo, dd test, etc, etc.

Hi

A SCSI device on bus 1 is having problems, more often than not a disk.

Down the server.
Power off
Fit anti static strap (Wrist strap).
Remove and reseat disks/ devices on this bus.
Remove and reseat cables on this bus.

Power up
Watch for errors on console.
If non then monitor syslog for errors.

Reason - after time connections oxidise slightly and can affect the devices so a remove and refit cleans the contacts on cables and devices.

Warning:- Ensure that you have a valid full backup and Ignite copy of the server as there is a possibility that if it is an imminent disk failure then during a reboot it is most likely to fail.

On that address....

1f is hex for 31

If you go to /dev/dsk you will note your disks are all 31. So when you see lbolt errors remember to translate the first 2 characters/digits from hex to decimal and you will be able to identify under /dev what type of device your having the problem with..

The rest gave the exact disk address...
012600 equates to c1t2d6

Hope this helps for today and future lbolt issues..
Rgrds,
Rita

Rita's right, sorry for my typo mistake, should be c1t2d6.
