Invalid backup header on device /dev/rmt0.1!

Question:

Env:
  AIX 4.2.1
  RISC unknown (server) and  R50 (High Node)
  sysback 4.1.4.1

Problem:
  The customer has a full system backup which was created
  with sysback 4.1.2.  The customer does a network boot
  from a the server which is running sysback 4.1.4.1

  We choose option 3 "INSTALL the System with Current Settings"

  We get this error message:

  Invalid backup header on device /dev/rmt0.1!

It appears the headers are totally different from ver 4.1.2
and 4.1.4 1 of sysback.

Version 4.1.2 sysback Header:
--------------------------------

Date:   Wed Jan  7 14:32:36 1998
User:   root
Host:   modj30
Type:   TOC - System Backup
Data:   rootvg
Size:   464 megabytes
Packed: N
Buffer: 64 Kbytes
Bkend:  B
Image Volume: 1


I had the customer make this change within this script on the
server system.

1.  cd /usr/lpp/sysback/inst
2.  cp sysinstall sysinstall.org
3.  vi sysinstall

  Search for this line:
[ -z "$volnum" ] && grep "\^Volume:" /tmp/..header | read x volnum x


----------------------------
Change it to look like this:
-----------------------------

[ -z "$volnum" ] && grep "Volume:" /tmp/..header | read  x x volnum x

Get rid of the \^ in front of the word "Volume:"   Also add a "x" as
well
 
4.  Reboot the client and try the install again

Fixed with the new release of sysback.rte
