Issue a "q vol stat=fill f=d" to see the access state and the error
state. We periodically have filling volumes get an I/O error while
writing. ADSM changes their access state to read-only and sets them to
the error state, then grabs another scratch tape and puts it in the
filling state. I have a cron job (AIX 3) that periodically issues a
"q vol stat=fill acc=reado" to look for these volumes and generates
Email to the ADSM administrators so they can follow-up.
