problem on defining VTL device on TSM /dev/lb0

[kaelo]

Hi Guys,

I'm redefining my VTL drives on my TSM but when I tried to do the command below to define the path I got an I/O error. It seems that it can't see any /dev/lb0 on my AIX.

Does any has encounter this before? Does the lb0 should be visible on "lsdev -Cc tape" command just like the "smc0" for IBM tape libraries?

Appreciate any advise.

DEFINE PATH TSMPRD I500_VTL SRCTYPE=SERVER DESTTYPE=LIBRARY DEVICE=/dev/lb0 ONLINE=YES

ANR8418E DEFINE PATH: An I/O error occurred while
                          accessing library I500_VTL. (SESSION: 130)

- Thanks Kael

delete the paths using rmdev and rerun cfgmgr and try, it may help

I did this already and still the same.

My 2 Cents.

You do not say what type of VTL you are running but from the name VTL_i500 i guess that you are running either a Falconstor VTL or a Quantum
If it is falconstor you have to disable DPF (data path failover) and possibly CPF (Control Path Failover) in the ibmtape device driver.

Use TSM device Driver

You need to use the the TSM Device Driver if you are not emulating an IBM library to find the library/changer device type. If you are emulating IBM type drives, you can see them with just using ATAPE. If that is the case cfgmgr will find them... an lsdev -Cc tape will only show your tape drives and then an lsdev -Cc library will show your library/changer.
