Full Discussion: Remove Faulty disk from HP-UX LVM VG

Is this the same computer as the original computer in this post:
HP-UX server cloning

What output do you get from this "ioscan" enquiry:
Code:
ioscan -fnCdisk

Assuming this is one mirror of the system disc and you have physically removed the disc or corrupted it, this is a delicate sitution. The tactics depend on whether you want to replace the disc or permanently remove the disc. Because you are tempting fate with your cloning guesswork it has to be assumed that this is not a straightforward disc failure.

If you don't already have a copy of "When good disks go bad", then it is currently on this link. Well worth a read to help you consider your options:

Based on your previous posts we assume that you have no backup of this system.

pvck

PVCK(8) 						      System Manager's Manual							   PVCK(8)

NAME

       pvck - check physical volume metadata

SYNOPSIS

       pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvck checks physical volume LVM metadata for consistency.

OPTIONS

       See lvm for common options.

       --labelsector sector
	      By  default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0.  This parameter allows you to specify a
	      different starting sector for the scan and is useful for recovery situations.  For example, suppose the partition table is corrupted
	      or  lost	on  /dev/sda, but you suspect there was an LVM partition at approximately 100 MB.  This area of the disk may be scanned by
	      using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

	      pvck --labelsector 204800 /dev/sda

	      Note that a script can be used with --labelsector to automate the process of finding LVM labels.
