Hiya,

Looks like you have a faulty disk - check the hardware lights :-)

Cheers,
James

Hi,
Check whether fault LED in glowing in any one of the disks .
If yes , note down the hardware path of the disk and relate with the filesystem it is mounted. Try accessing the filesystem.
If it is a hard problem, and if the disk is
connected in a external disk station , try recycling the power of the disk station.
Also try rebooting the server once.

regards,

Hi,
Try an
#ioscan -fnC disk
Are there disks NO_HW ?

You could also check the disks with cstm ...

Hope this helps,
Tom

Hi

It sounds like something wrong with H/W. Do U have any diagnostic S/W installed? If yes, Take it's help to find out root cause. Otherwise check for any HDD is mis behaving or not...U can use #ioscan -fnC disk, or diskinfo, or dd like command to verify the disks..

Best of luck

hI,
thnks for the inputs , i will work on this.

BTW, the "dev: ..." information points to *which* disks are giving problems:

> Jun 10 15:26:03 hppd03 vmunix: SCSI: Read error -- dev: b 31 0x030200, errno: 126, resid: 2048,

31 and 0x030200 are the major and minor numbers
. I.e.

ll /dev/dsk/* | grep '31 0x030200'

should give you the device file. lssf(1M) then gives you the hardware path.

Hi Nitin,

Looks like SCSI disk problem. Could be a terminator problem since the device no is erratic,

0x030200 --> /dev/dsk/c3t0d2
0x030400 --> /dev/dsk/c3t0d4

Hope this helps.

To explain the difference between Sanjay's simple method and my more complex method:

Sanjay's method gives what the device file names *should* be. My method gives the devices names as they *are*.
