sysback. trying to restore a volume group to a raid device.

Env:
  sysback 3.3.2.5
  AIX 3.2.5
  Risc 59h

Desc:
Trying to restore volume group.  The customer gets back a 
netative number on the pv for the raid disk.  And sysback states
they do not have enough -1644mb to restore with

Action:

bootinfo -s hdisk3  
  25836
So the raid disk is 25gb in size for hardware mb.
It appears that sysback is messing up when converting it to
software mb.  It appears that 25gb is too large for the eval
problem in the ksh script. 

Here is a workaround:

cd /usr/lpp/sysback/inst
cp sysinst.lib sysinst.lib.org
vi sysinst.lib
find 104857 and change it to 10486
on the same line change 100000 to 10000

rerun the remakevg command

This is caused by a limitation of the Korn shell not able to handle
a number over 2gb in size.  In AIX 3.2.5 the bootinfo only gives the
number in hardware meg bytes.  In 4.1 the bootinfo returns the software
meg bytes.  So this problem does not exist at AIX 4.1, only 3.2.5 
We may loose some granularity with this workaround, but it will work.

Next Action:
  Closing with customer approval
