Ruud,
I'd look at the Fibre Channel Adapter on the ESS. It could be functioning
just well enough to allow a stable link to your SAN (therefore your paths
will look good), but it may not be seeing the DASD inside the ESS. FCAs
are hard to troubleshoot because a loop back test isn't a very reliable
test. All it tells you is that light is traveling successfully around the
loop - it doesn't prove that actual communications are occurring.
Good luck on this one, and please let me know what you find out!
Thank you,

it seemed Jeff did not get this email the first time therefor i had to sent
it again:
thanks Becky, Jeff
However, I think this is not the answer I was looking for because the
problem still exists:
On this server we could see some, but not all, of the disks on each path.
Furthermore, when a disk was missing, it was not visible down any path and
this was not fixed by running cfgmgr more times.
any ideas ?
thanks in advance

Ruud,
Becky is right, but here's a way you can do it that seems to me to be a
little less disruptive.
Use the "-l" option and the name of the adapter on the end of your command.
Do this once for each device, then one plain config-manager to put the
vpaths into AIX's ODM...
Example if you have three paths:
cfgmgr -l fcs0
cfgmgr -l fcs1
cfgmgr -l fcs2
cfgmgr
This way, cfgmgr only runs once (for the specified device each time) and is
much faster if you have many devices on a high-end server.
Thank you,

If you have more then one path going to data then you need to run cfgmgr for
each path. For example if you have 3 paths then you often need to run
cfgmgr 3 times to get all of the paths.

Guys
this is not really a TSM matter but perhaps someone could help me out here:
At the moment we have a concerning situation on a ESS. When we change
ESS-ports for an AIX-server without touching the assigned LUN's of the
server, only a Hba-swap on the ESS, our customers complain about the
availability of the disks from the servers point of view. They say that
after we performed this action and they have deleted the disks, rebooted the
server and ran config-manager, they still have missing disks (some disks are
visible, but not all of them), note that before the Hba-swap, the server
could see all its disks.
When they boot the server again a couple of days later, all the disks are
visible again without us performing any actions on the ESS or the switches.
any ideas ???
thanks
