1) AIX version is: 6100-08-00-0000 is the DVD release. You should update to a SP.
2) Get the SP files using smit suma or FixCentral, download.
3) Once you have the downloads, smitty update_all.

Lastly, why are you using backup (i.e., backup by inode) rather than backupbyfilename.
Usually backups are by filename and/or made for a whole volume group.
# savevg -i -f /dev/rmt0 vgName
or
# cd /some/directory; find . | backup -if /dev/rmt0

In your case it looks like the last option would be:

Code:

# cd /backup; find . | backup -if /dev/rmt0

Note also, if doing backup by inode - as your example - you should unmount /backup first
Example (where I write to a file, not a tape)

Code:

michael@x054:[/home/michael]umount /audit  
michael@x054:[/home/michael]backup -0 -f /data/backups/audit.backup /audit
backup: The date of this level 0 backup is Tue Mar 19 13:30:21 CUT 2013.
backup: The date of the last level 0 backup is the epoch.
backup: Backing up /dev/rhd12audit (/audit) to /data/backups/audit.backup.
backup: Mapping regular files. This is Pass 1.
backup: Mapping directories. This is Pass 2.
backup: There are an estimated 1183 1k blocks.
backup: Backing up directories. This is Pass 3.
backup: Backing up regular files. This is Pass 4.
backup: There are 1147 1k blocks on 1 volumes.
backup: The backup is complete

If you continue to have these lseek errors, file a call with IBM or your BP for support and diagnosis.

I tried to use lseek system call to determine the number of bytes in a file. To do so, I used open system call with O_APPEND flag to open a file.

vgcfgrestore

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

NAME

       vgcfgrestore - restore volume group descriptor area

SYNOPSIS

       vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|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

       -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 Vol-
	      umeGroupName.

       -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  vgcfg-
	      backup.

       See lvm for common options.

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.
