The ability to support multiple drive types in StorageTek ACSLS or
LibStation libraries is enabled through the use of the external library
manager interface and an external library manager. By presenting multiple
virtual libraries through this interface, you can enable TSM to use multiple
drive types. This is valid for all TSM levels.

We run AIX 4.3.3, have gone from TSM 3.1 to 3.7 to 4.1 to 4.2.1.5..... Etc.

On ADSM 3.1, you needed ACSLS to support some types of devices that ADSM
didn't support native.

And at one time you could put two types of drives in the library if you used
ACSLS, and TSM doesn't support that with native SCSI (and I'm not sure you
can still do this at TSM 5.x, even with ACSLS).

Once we evolved past those 2 requirements, we dropped ACSLS and went to
TSM's native SCSI support.
It's a much simpler configuration and works just dandy if TSM is the only
application using the library.

We just bought a used STK L700 with 4 DLT7000 drives.  We
have TSM 5.1.5.2 on AIX and I am confused as to why/if I
would need to use ACSLS to manage the library?  Does ACSLS
provide any features not available with TSM's native
library manager?  We will want to share this L700 with
another TSM server and I can't see why native scsci
library won't be a good choice?

Any advice?
