Excellent. I think IBM need to work more on device driver stability
development.

Hi Ian,
The problem above resolved. I managed to get the problem tape drive
MT6.0.0.1 working. Just need to restart the tape library and define back
all the drives.
Thanks all,
Regards,

The CPF and DPF enable/disable is just a registry change. There should
by some registry scripts in the ultrium unpack directory, in a reg
folder.
These functions are for path failover- you can define control paths for
the library on multiple drives (i.e. mapped over multiple fabrics). This
CPF function then aggregates the device. If you don't have the correct
functionality configured, then disable it.
It is best practice to configure the library manager and clients with
the same driver version and keep them configured the same, i.e. ensure
the functions are disabled on all devices. N.B. it will require a reboot
to activate the registry change after you have run the script.
The actual change looks like the following:
Windows Registry Editor Version 5.00
[HKEY_LCAL_MACHINE\SYSTEM\CurrentControlSet\Service s\ibmcgbs2k]
"FailoverDisabled"=dword:00000001
[HKEY_LCAL_MACHINE\SYSTEM\CurrentControlSet\Service s\ibmcgbs2k3]
"FailoverDisabled"=dword:00000001

Hi Ian,
Regarding the CPF, is it a must to disable the functions? What's the
different of having it disable or enable? Where can I get the script to
disable the CPF?
Do I need to do the rollback on the library clients too?
Thanks,

You are on a much later device driver so I would try disabling the
failover functions first before you roll back.
Wehen we did this it resolved the problem straight away. We also had
major server stability issues, where the server would blue screen and
only be recovered by ASR.
After a difficult period we pinned this down to the ultrium drivers.
Are you using LT tape drives? Are the AIX boxes library clients or
just normal clients?

Hi
What ultrium driver versions are you using?
We had this problem after upgrading the ultrium device drivers to
6.1.1.2. We had to roll back to 6.0.8.2.
Ensure that the CPF and DPF functions are disabled in the registry by
using the scripts if you are not using this function.

Hi all,
I'm having this error "Unable to open drive mt6.0.0.1 error no=170"
after I backup 3 clients.
Currently the TSM server 5.3.2 is running on Win2003 server and the 3584
tape library while the clients run on AIX5.1. There are 4 tape drive
path define connected with 2 SAN switch.
Initially the backup run successfully and the error occur after I backup
the
3 clients. I have tried to dismount the volume on the mt6.0.0.1 drive
but the drive is NT in idle state.
Really hope if anybody knows the solution of this problem
Thanks,
Regards,
Zareyna Salim
