OLT = Object Location Table

The metadata (filesystem data, not user data) on a Veritas Filesystem is stored with the user data on the same disk/volume/LV . The OLT is very important because it tells VxFS where to find all the inodes, or extents or ..... If this is missing, basically, your filesystem is dead. There is a backup copy, but seems like this is missing as well ...... and due to the fact that you are missing PVs out of your VG. If you can not find these PVs, you will have to restore the filesystem (sorry)

vgcfgrestore

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

NAME

       vgcfgrestore - restore volume group descriptor area

SYNOPSIS

       vgcfgrestore  [-d|--debug]  [-f|--file  <filename>] [--force] [-l[l]|--list] [-h|--help] [-M|--metadatatype 1|2] [-t|--test] [-v|--verbose]
       VolumeGroupName

DESCRIPTION

       vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by  vgcfgbackup.   You  can	specify  a
       backup  file  with --file.  If no backup file is specified, the most recent one is used.  Use --list for a list of the available backup and
       archive files of VolumeGroupName.

OPTIONS

       See lvm(8) for common options.

       -l, --list
	      List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName.  May be used with the
	      -f option.  Does not restore VolumeGroupName.

       -f, --file filename
	      Name  of	LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName.	Often this
	      file has been created with vgcfgbackup.

       --force
	      Necessary to restore metadata with thin pool volumes.
	      WARNING: Use with extreme caution.  Most changes to thin metadata cannot be reverted.  You may lose data	if  you  restore  metadata
	      that does not match the thin pool kernel metadata precisely.

REPLACING PHYSICAL VOLUMES

       vgdisplay  --partial  --verbose will show you the UUIDs and sizes of any PVs that are no longer present.  If a PV in the VG is lost and you
       wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate)	to
       initialise  it with the same UUID as the missing PV.  Repeat for all other missing PVs in the VG.  Then use vgcfgrestore --file filename to
       restore the volume group's metadata.
