A problem about recovery from tape

[Wang,MinJie]

Hey everyone
when i used a tape drive to recovery a L1000 system("sea" then "bo p0" and wait)
there was some warning information below:
=========================================
* Archive extraction from tape is beginning. Please wait.
LVM: vg[1]: pvnum=0 (dev_t=0x1f020000) is POWERFAILED
DIAGNOSTIC SYSTEM WARNING:
The diagnostic logging facility has started receiving excessive
errors from the I/O subsystem. I/O error entries will be lost
until the cause of the excessive I/O logging is corrected.
If the diaglogd daemon is not active, use the Daemon Startup command
in stm to start it.
If the diaglogd daemon is active, use the logtool utility in stm
to determine which I/O subsystem is logging excessive errors.
==============================================
Then no action!
Have you any idea?
Thank you

You have problems with disk-0x1f020000
(c2t0d0). Check it's cables/connections etc. Unless it has no problems, you can not recover onto that drive. Else, use another hard drive.

LVM: vg[1]: pvnum=0 (dev_t=0x1f020000) is POWERFAILED

is giving the problem information clearly. Check the disks whether all are active to access.

# ioscan -fnC disk

There're three disk in the system and they're empty
How can I recogonize which disk has error without pull it out to another system to diagnose with stm

It will have hardware address.

[Wang,MinJie]

Adress? Is it 0x1f020000?
How to transplate it into the form like x/x/x.x.x.x?

Hi,

Try:

cd /dev/dsk; ll |grep 0x1f020000
This will give you file name (/dev/dsk/cxtydz)
The next step is
ioscan -kfnCdisk
and look for HW address of the disk
