DEAD hdisk in vpath

[ereshatezer]

Hi,

I got a new system with vpathes on it, but I do not have too much experiance with it.
I am facing with the following problem:
In one of the vpath the status of one of the hdisk is: DEAD

How can I get more about this error and how serious the problem is?

DEV#: 3 DEVICE NAME: vpath3 TYPE: xxxxxxx POLICY: Optimized
SERIAL: xxxxxx
==========================================================================
Path# Adapter/Hard Disk State Mode Select Errors
0 fscsi0/hdisk6 OPEN NORMAL xxxxxxxx 0
1 fscsi1/hdisk10 DEAD NORMAL xxxxxxxx 4



In the errpt there were 3 messages related to this problem:

FCS_ERR2
FSCSI_ERR4
SC_DISK_ERR3

hi,

is this happening on all disks or just the one you list above.

try a dd if=/dev/hdisk10 of=/dev/null bs=64k

after 30 seconds interrupt it with ctrl c
(does it show p as any errors when doing dd)
check your physical connection i.e. your card see if any lights flashing which means error state , check cable.

check from your disk array if it can see both paths successfully

This happened only for hdisk10. The other disk are OK.
Here is the result:

dd if=/dev/hdisk10 of=/dev/null bs=64k

0+0 records out.

looks like your adapter/cable could be bad is this san a shark or what. The disk is not bad but the path to it is

Hello,

You were right! The FC-cabel was bad.
The problem has been solved now. Thank you for the hints.
