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.
