Hi Eric,
If I understand you correct.
You can define a drive and the path.
As soon you rename the drive the path is stop working?
And now you can't you update the path anymore or delete / define it again?
Have you compare the output from q drive f=d before and after rename?
Same thing with q path drive server srct=server f=d
Do also look on Devconf.out in your AIX filesystem. Maybe it tells you the
wrong path in their and have problem to update that file for you? (Security or
maybe something else)

Hi Richard!
They are identical...
It must be a TSM issue then. I will try to create a path to the renamed drive
tomorrow (which will fail) and then try to create a path to the same drive on
the other TSM server on the same host. If that one does not fail, it must be
related to that specific TSM server instance (running the same TSM version) so
I will have to schedule a stop/start to see if that solves anything.
I'll keep you guys posted, thanks for now!
Kind regards,
Eric van Loon

I don't have any real idea, but if it works as /dev/rmtX, and not after
renaming - I wonder if the binding is getting messed up on the rename.
Check the device attributes before the rename, and then after, and see if
the scsi_id, wwn, lun_id is the same.

Hi Richard!
It's a virtual library from EMC in which I created two libraries, one
for the first TSM instance, the other one for the other instance. TSM1
uses the renamed devices (/dev/253 with drives /dev/253_0 to 29) and I
could create paths to the drives succesfully on that TSM instance. On
the other TSM instance, I can only use the devices as long as the name
starts with rmt. As soon as I rename them to 254_0 to 29 (our standard
naming convention) I receive an I/O error when I try to create the path.

I'm a little confused on what you are trying to do. Is this one new lib
being shared between 2 instances via library sharing (one set of rmt/smc
devices), or, 2 new libs - one for each tsm instance (separate sets of
rmt/smc devices - one set to each tsm instance)?
Also, are you using Atape multi pathing?

People, please help me, I'm lost...
We are running two TSM instances on one AIX host. I'm trying to create a
new library on both of them. The first one was no problem and everything
went as expected.
We have always used a script which renames the library an drives
detected by cfgmgr to math the SCSI id of the library. So if a smc0
(SCSI id 254) and a rmt0 is found, the script renames the library to
/dev/254 and the drive to /dev/254_0.
The script uses the command chdev -l <rmtdevice> -a
new_name=<scsid_drivenumber> to do this.
Now, on one of my servers, I cannot create a path to renamed drive! I
can create a path to /dev/rmt0, but as soon as I rename it to /dev/254_0
I get an I/O error when I try to create the path.
To make it even stranger: when I rename the drive to rmteric, I can
create a path successfully! But the name rmeric (so whithout the t)
results in the I/O error again.
I really cannot find the cause, especially since everything works as
expected on the other TSM instance on the same host!!!
Does anybody out there have any idea what could cause this strange
behavior???
Thank you VERY much in advance for any help!
