This one isn't difficult... you have a tape which has media errors (TSM has a
problem writing to it) and the next stanza in your actl will probably say that
the tape access is read only. I have a 3575 L32 and approximatly 1 percent of my
tapes over the last 8 months or so have ended up in reado access due to write
errors. If there is an excessive amount of errors, a drive may be downed if the
offending volume continues to be mounted but typically TSM handles write errors
fairly well. If you distrust the tape (it is in an error state or readonly), you
can move the data on it to other volumes within its copypool. Also, you can
check your error log on your system (you didn't say what O/S you are using) to
see if these errors are reflected in this log. On an AIX system, they will be
and if there is a bad drive, you can see what remedial things need to be done.
Usually, for media errors, the error report will suggest that you have a bad
tape or need to clean the tape heads.
