Hi Everyone,

I have a 3584 library (connected to AIX) for which I need to change the
device file
used in the library path.  It currently points to /dev/smc0 and I need to
change it
to /dev/smc4.

When run the following cmd, I am told that the lib is in use . . .

  update path tsmlm2 3584isoc srct=serv destt=library  device=/dev/smc4
  ANR8450E UPDATE PATH: Library 3584ISOC is currently in use.

I then try to put the path offline . . .this works, but the above command
still reports that the lib is is use.

  update path tsmlm2 3584isoc srct=serv destt=library  online=no
  ANR1722I A path from TSMLM2 to 3584ISOC has been updated.

  update path tsmlm2 3584isoc srct=serv destt=library  device=/dev/smc4
  ANR8450E UPDATE PATH: Library 3584ISOC is currently in use.

There ARE tape mounted in some drives.  Do I need to get
all the drives offline and demounted to do this?

What do I need to do to change the device of a library path?



What's happening . . .  We are upgrading the AIX server this saturday by
adding 2 additional I/O drawers.  These drawers will need a new/additional
RIO cable.  The RIO cables needs to use the same slot as one FC adapter
(slot 4 of the processor unit), so the FC adapter in slot 4 will be
removed.  That FC adapter has one set of lib/drives
defined on it, AND, those are the smc/rmt's used on the PATHs in TSM.
I added another fc adapter to the lpar and moved the drive paths to these
new RMT devices, but I'm having trouble moving the lib device.
