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.

BACKUP_DELHOST(8)					       AFS Command Reference						 BACKUP_DELHOST(8)

NAME
       backup_delhost - Deletes a Tape Coordinator entry from the Backup Database

SYNOPSIS
       backup delhost -tapehost <tape machine name>
	   [-portoffset <TC port offset>] [-localauth]
	   [-cell <cell name>] [-help]

       backup delh -t <tape machine name>
	   [-p <TC port offset>]
	   [-l] [-c <cell name>] [-h]

DESCRIPTION
       The backup delhost command deletes the indicated Tape Coordinator entry from the Backup Database. It is then impossible to submit backup
       operations to that Tape Coordinator, even if it is still running. To keep configuration information consistent, also remove the
       corresponding entry from the /var/lib/openafs/backup/tapeconfig file on the Tape Coordinator machine.

       To list the Tape Coordinator machines and port offsets defined in the Backup Database, issue the backup listhosts command.

OPTIONS
       -tapehost <tape machine name>
	   Specifies the hostname of the machine housing the Tape Coordinator to delete.

       -portoffset <TC port offset>
	   Specifies the port offset number of the Tape Coordinator to delete.	If omitted, it defaults to 0. If provided, it is an integer
	   between 0 (zero) and 58510, and must match the port offset number assigned to the same combination of Tape Coordinator and tape device
	   or file in the /var/lib/openafs/backup/tapeconfig file on the Tape Coordinator machine indicated by the -tapehost argument.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
	   the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
	   details, see backup(8).

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES
       The following command deletes the Backup Database entry for the Tape Coordinator with port offset 2 on the Tape Coordinator machine
       "backup3.abc.com":

	  % backup delhost -tapehost backup3.abc.com -portoffset 2

PRIVILEGE REQUIRED
       The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged
       onto a server machine as the local superuser "root" if the -localauth flag is included.
