Hi,

I'm not sure that it's possible to repair a disk after PHYSICAL failure.
If you don't see the failed disk with ioscan or diskinfo doesn't provide a normal information or the following command:
dd if=/dev/rdsk/XXXX of=/dev/null bs=32768k
gives a lot of errors, the disk should be replaced by a new one.

Hi Victor,

thanks for suggestion. What software/commands, we must have on the system required to trouble shoot and recover the system . like as i know following required

Diag tool online & offline.
data full back up.
copy of get_config
Ioscan -fn output hard copy
output of /etc/fstab
output of strings /etc/lvmtab

as other software suggestion

get the free Ignite/UX software installed, and create a make_recovery_tape archive.
This provides a bootable copy of the system on tape that allows for fast and easy recovery.

Hi,
make_tape_recovery (Ignite) is a good tool for system backup (volumegroup vg00). Even better is to configure an Ignite server (make_net_recovery).

For other volume groups you can use fbackup or better, Data Protector.

Ignite make net recovery is really the way to go. It requires you have an ignite server to store the images, but it allows a restoration of the OS pretty easily and quickly over the network.

As far as boot disks (or even non-boot) mirror disk is the tool to use. As long as you don't lose both mirrors, you can always recover.
