[nagarjuna reddy]

Hi all,

I am new to this area, pls. clarify my doubts regarding the errors in syslog file.
the errors are like this

vmunix: SCSI: Write error -- dev: b 31 0x011002, errno: 126, resid: 8192

vmunix: LVM: Failed to automatically resync PV 1f011002 error: 5

vmunix: SCSI: Read error -- dev: b 31 0x011002, errno: 126, resid: 1024

pls. reply me, these errors are critical to my database??

Hi,
Looks like a disk problem.To get what disk it is do ll /dev/dsk/* | grep 0x011002.

dd if=/dev/dsk/cxtxdx of=/dev/null bs=4k
Check if it returns any error.
If there is any error then you need to log a H/W case with the vendor.

If this is a SCSI disk the you need to check the following also.

SCSI termination may be loose.
may be SCSI data cable problem.

If this disk is a part of an external storage device , worst case it cud be a problem with the slot of the stoarage device too.

Please don't forget to assign points.
Regards,
Ani

i didn't get anything.

i typed the command

ll /dev/dsk/* | grep 0x11002

is it correct?

[ani007]

you did a mistake

#ll /dev/dsk/* | grep 0x11002 --incorrect
it should be 0x011002


so fire this just copy paste
#ll /dev/dsk/* | grep 0x011002
