Yesterday, I accidently changed the maxcapcity parameter for my main tape device class to 22 mb instead of 22 GB. As a consequence, our TSM server (v 4.2 on OS/390) has used up most of our tapes. I have corrected the parameter, but that does not help with the tapes written to while the 22 mb value was in effect. Is there any easy way to tell TSM that the tapes it thinks are full with only 22 mb really have plenty of room left? So far, I have been using the move data command to empty out these tapes, but that is only does one at a time. I tried using migration, but migration appears to be based on percent utilization, not on amount of data. Has anyone ever made this mistake and found an easy way to rectify it?
Thanks for any suggestions.
