Hello all!

 After updating ADSM 3.1.2.1 to 3.1.2.40 we have had 
 several I/0 -errors with DLT IV-tapes. This will change tapes to readonly
or unavailable access.  Now we have almost 5 per cent unavailable tapes from
all of our tapes. 

 Our configuration:
 Sun UE5000 + A5000 + Solaris 2.6 + STK9740 library with 
 10 x DLT7K tapedrives. 

 Have anyone had same problems? Do you know what are the right microcode
levels to those tapedrives? How can we correct the problem?

 Here are few messages from activity-log:

 Any help would be greatly appreciated.
