Re: TAPMLB01

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

It makes perfect sense.  The tape library has functionality to control 
the robot and other functions.  Hence it has a device type.  IBM i 
created it for you since it sees the library.

IBM i also sees some tape devices so it went ahead and configured that 
for you too.  As you have found, to use the tape device, vary off the 
controlling tape library device and the tape unit inside the tape 
library becomes a stand alone tape device.  Use the tape library as an 
auto loader (sequential mode) or manually mount tapes using the front 
panel or GUI interface.

So in a stand alone environment vary off the tape library, vary on the 
tape device.

In a BRMS managed environment, vary off the device, vary on the tape 
library.  There is one more step in that you have to allocate the drive 
to the tape library, use WRKMLBSTS to do that, but that can wait for you 
to implement BRMS.
