# rmdev -dl hdisk#

if that doesn't work then make sure the fibre channel adapter that only has
those two disks on it and remove that with the -R option:

# rmdev -R fibre_channel_adapter

This will remove all child devices attached to the specified fibre card
adapter.

First, let me say..
Dear Lord, the IBM web pages are a pain to dig through and find what you
are looking for.  Couldn't find any knowledge bases or anything to help me
resolve the issue I have... so.. here goes.

AIX 4.3.3
My TSM server is a pSeries with two Fibre Channel Adapters installed,
through which we access data on the ESS (shark) and the LTO tape drives (I
know, bad idea).  Each of the fibre cards is connected to its own fibre
switch.  Each switch has two connections to the Shark (four data paths to
the Shark).

We have been trying to add some additional Shark storage to the TSM server.
After the Shark guy did his thing, I ran cfgmgr, and thinks didn't look
quite right.  The two old "vpath" devices each showed four disks (hdsikX),
two on each of the two fibre cards (fscsi1, fscsi0), just like they always
have.  One of the three new "vpath" devices showed four hdisks on two
different "fscsi" devices, but the other two "vpath" devices only showed
two hdisks, one on each fscsi.

lscfg showed a bunch of new disks, mostly "available", but four were
"defined".  I decided to delete the three new "vpath" devices, and all of
the associated "hdisk" devices, including the defined ones.  As I got to
looking, I saw something odd...

Note the **** lines.
I have two entries for "hdisk2" and two for "hdisk3".  Smitty won't let me
remove them (not enough information to uniquely identify the device) and
similar error messages for "change/show charactaristics".

How can I remove "hdisk2" and "hdisk3"?  The 10-78 and 10-68 devices are
the fibre cards.

Thanks in advance
