Have you had the firmware on the drives brought uptodate?

IBM.. and it is happening with frequency on tapes that are new, as well as
tapes we have had since day one. I cleaned the drives manually (using the
panel on the 3584), but we are still getting a few unavailables each
night.
I did some research on the tapes that went unavailable over the last 30
days, and all of the ones I checked had another error nearby.. indicating
that the dismount of that volume failed, and it may still be in the
drive... yet, they never are, they seem to be dismounted successfully.
I am still trying to figure this out... if anyone has a suggestion.
Thanks

Subject: 3584 Cleaning Frequency
What is the normal clean frequency for LTO-1 drives in a 3584? I have the
drives defined to TSM with a cleaning frequency of "none", and the 3584
library set to Automatic cleaning, per recommendations. Yet, when I use
the front panel of the 3584 to look at the cleaning cartridges, one has
never been used, and the other has only been used 4 times. We have had
this library for nearly 2 years now. I started looking at this because of
the number of tapes that are marked read-only or unavailable per night
(anywhere from one to 7 so far, usually 2 or 3 per night). The eight
drives show as follows:

These tape drives have transferred thousands of terabytes of data (what's
that.. exabyte?), apparently without cleanings. What can I check to find
out why, other than what I mentioned above (Lib set to AUTO, and drives
set in TSM to none).
Thanks in advance
Todd
