Thanks for the response.  So, if I don't have any LTO2 media, I can just
leave the mountlimit set to DRIVES?  But you're saying that TSM will use
the LTO1 drives until they are all utilized before using an LTO2 drive?

Moin Kevin,

This week we added two LTO2 drive into an Frame with four LTO1 Drives.
It works. We changes the devc in the way you describe it. In the LTO1
Devclass we changes also the parameter mountlimit to "numbers of LTO1 +
half of LTO2" => 5. So we have one LTO2 drive for LTO2 Media. The
recommodation from IBM is this formular or mounlimit = numbers of LTO1
because TSM uses for LTO1 Media the LTO1 Drives first. We added a second
devc with format=ultrium2c for stgpools with LTO2 Media.


Mit freundlichen Gruessen - Best regards
