Currently I am running ADSM V3 AIX server using STK 9840 Drives.  The
Device class I am using uses a DEVTYPE of GENERICTAPE.  This was
required years ago by the 3rd party vender OMI (Now known as Gresham
Technologies) when using their Advantape Device driver for AIX.  Well
the problem I am running into now is I am attempting to convert to my
new TSM V4.2 server on another physical machine.  The conversion and
UPGRADE DB works like a champ, the problem is when I try and access my
data on my 9840 tapes I get an I/O error reading the Tape labels.  The
only way to correct this is to use a DEVCLASS that has a DEVTYPE of
ECARTRIDGE.  This works I know because I was able to test it.  The BIG
problem comes in where TSM gives you no way to update the DEVTYPE in a
Device class definition.  I am currently working with TSM Level 2
support on this issue with no real progress as of yet.  TSM support is
telling me that I need to create a new Tape Primary storage pool on my
ADSM V3.1 that is using a DEVCLASS of ECART.  Tried this also and I get
similar errors when trying to write to this new Devtype on the old
server.  So I am stuck right now with my conversion.  Has anyone out
there run into this problem before, and if so, what did you do to get
around it.

Thanks for your input.
