LIF corrupt or not present

[Rob Yohn]

I have a 10.20 server that I was just notified giving the following error during a make_tape_recovery. Other output follows also. How can I correct this issue? It looks like the ignite tape has been failing for quite a while now.

Do as advised an re-initialize the LIF area ...

[Rob Yohn]

I am not familiar with the steps to reinitialize the LIF area. Can it be done while the system is booted from that drive?

It looks like this is the disk I am booted on that is generating this error message.

pg /stand/bootconf
# Boot Device configuration file
# This File contains information regarding the location
# of the boot LIF. It is used by the KERN-RUN fileset to
# update the boot kernel.
l /dev/dsk/c0t5d0

[Torsten.]

Do

# mkboot -l /dev/rdsk/c0t5d0

and check with lifls.

[Rob Yohn]

I issued that command and it gave the following error. I was able to watch the drive and it was being accessed during this command. No error messages in syslog and no red light on the drive.....

mkboot -l /dev/rdsk/c0t5d0
Could not open /dev/rdsk/c0t5d0: I/O error

My first response would be that the drive is bad..

How about this to prove it or not.

dd if=/dev/rdsk/c0t5d0 of=/dev/null

Let it read through the drive, if no IO error then back to the task at hand. If you get an IO error then you need to replace the drive.

Your disk at c0t5d0 is broken. You have probably been running on the mirror copy for quite a wg=hile, especially if you don't have EMS setup to notify you of disk errors and you don't look at syslog regularly.

Ignite/UX is a very useful tool to check the health of your system, especially disks and mountpoints. Ignite/UX errors mean that your system has got some problems.

Thanks to all that have replied. It looks like I do indeed have a failed/failing disk. Now on to the replacement procedures. Points have been assigned.

Hi,

Replacement procedure:
=======================
Since it is 10.20 I assume that the disks are non hot swapable.

=>Power off the server
=>Replace the faulty disk
=>Boot from alt disk
=>Interupt the boot and boot with qorum override(ISL> hpux -lq
=>vgcfgrestore -n vg00
=>vgchange -a y vg00
=>vgsync
=>lvlnboot -Rv
=>lvlnboot -b
=>lvlnboot -s
=>lvlnboot -d
=>lvlnboot -r
=>lvlnboot -v
