    I think that's correct: bootinfo -B is just checking whether the type of
    hardware is a viable candidate for a boot disk, not whether this particular
    disk has a good boot image.
     
    From the man page...

    Displays a 1 if the IPL code in the ROS on the machine running the
    command is capable of booting from the specified disk. Otherwise, the
    command displays a 0.

    I'm a bit surprised that bosboot worked: I'd have thought it would check.
     
    Older versions of AIX were a lot fussier about what they booted from. Not
    just things like SSA and fibre attached disks, but non-IBM SCSI disks were
    often not suitable. Updated system firmware might help. Likewise OS and
    drivers. But I wouldn't bet on it.

It may not be an operational issue with the command or o/s. It's probably
the disk type. How is the disk(hdisk2) connected to the system? Is it over
internal scsi, is it ssa, is it fibre? All of these factors play a role.
Also, is the disk IBM manufactured? I don't know if the: "bootinfo -B
hdisk#", command actually goes out and reads the disk? It may be based on
location code, and disk FRU/type? 
Thanks.

Disk not bootable after bosboot
	
Hi, 
  
I've got a server running AIX 4.2 (I know, too old) and I want 'hdisk2' to
be a bootable disk (hdisk2 is incorporated in rootvg and have the boot
logical volume 'hd5' defined on it). 
I have successfully done these commands : 
  
# bosboot -a -d /dev/hdisk2 
# bootlist -m normal hdisk2 
  
and to verify that hdisk2 is now bootable : 
  
# bootinfo -B hdisk2 
  
But "bootinfo -B hdisk2" returns the code "0" which means (according to
manpage) that this 
disk is not bootable. 
  
Do you know if informations gathered by this command are not "refreshed" 
by the command 'bosboot' or if there is a mistake in my strategy ? 
  
Thanks in advance.
