Re: TSM mtx devices unavailable after reboot?

I've seen this problem re-surface from time to time over the years.  We
have a little Rexx script that we run before bringing up our TSM server
that re-configures devices to get around this problem.  Here's our script:

#!/usr/local/bin/rxx

/*
   adsm.device.configure - configure ADSM devices that don't come up as
                           available, just defined.
*/

'/etc/lsdev -C -s scsi -S d'
q = queued()
xrc = popen('/etc/lsdev -C -s scsi -S d')
do while (queued() > q)
  parse pull dev state .
  select
    when (state <> "Defined") then iterate
    when (left(dev,2) = "lb") then nop
    when (left(dev,2) = "mt") then nop
    otherwise iterate
    end
  '/etc/mkdev -l' dev
  end
'/etc/lsdev -C -s scsi | /bin/sort -k3'

This works with Regina Rexx.  It's quite simple, and i'm sure someone could
write a shell script or perl script that does the same thing.

TSM host is AIX 4.3.3

Recently upgraded TSM server from 4.1.3 to 4.2.1.15.
The install removed the lb0 and mtx devices.
I used smitty to put them back and they worked fine.

Now every time the host is rebooted, the lbx and mtx devices come back as
"Defined", but not "Available", and I have to put them back with SMIT again.


It's not a problem with the devices, because all that is required to fix
them is to start SMITTY and CONFIGURE them.

I've not seen this problem before.  Anybody know what causes this?
