ITEM: BT9000L

The sbdevice command is core dumping

Question:

Env:
  AIX 3.2.5
  RISC 590
  sysback 3.3.3.12
  Tapes rmt0 7332,  rmt9 1/4" 150mb,  rmt10 4mm 2gb

Desc:
  Customer creates these virtual devices

  vdev0 rmt0              seq
  vdev1 rmt9              seq
  vdev2 rmt0 rmt9         mult-copy
  vdev3 rmt10             seq
  vdev4 rmt0 rmt9 rmt10   mult-copy
  
Then the .remote_access file looks like this:

+all:+all:vdev0 vdev1 vdev2 vdev3 vdev4::

When the customer runs this command from the client
sbclient mod590 sbdevice -r vdev4

The sbdevice command core dumps on the server system and 
the sbclient command returns a return code of 1 on the
client side.

The command runs correctly without error on the local 
system where the tape drives and virtual devices are 
configured, but only fails remotely.
Once I remove one of the vdev\# from the .remote_access 
file the command works fine on the client system.

When the file looks this way it seems to work correctly
+all:+all:/dev/rmt0 /dev/rmt1 /dev/rmt2 vdev0 vdev1 vdev2 vdev3 vdev4::

So I am puzzled on what the problem seems to be

To work around the problem, I have had the customer just 
put a all instead of the device names


Description:
  Core dump sometimes occurred when running remote
  sbdevice, sbread or sbwrite commands when there were
  multiple virtual devices configured on the server in
  the .remote_access file.

Fixed with sysback 3.3.3.13

Next Action
  Sending this out to the customer
