You should probably check your act log for that specific time looking for an
indication of why (Sense data, I/O, etc...)
Do you have an automated library? If so, you can check error logs on the
console.

To get them back on line...
You can power them off , back on  and try to do an "UPDATE DRIVE" on them.
(help update drive)
Again, if you have an automated library, you can make your drives available
through the GUI interface on the console.

Many other rebel things to try like deleting and re-adding , rebooting,
recycling ADSM, calling a CE.
Good luck

        I had 'q drives' and thats why it couldn't find that command(Steve,
thank
        you). It shows now that the drive is not available. There is no tape
mounted
        in there. I also tried cleaning them. It had been working fine for
last 7
        months. Any idea why this could happen or how to put them back on
line?

        TIA.

        Dwight,
        q drives says unknown command. But the other 2 are as follows:
        adsm>
        q mount
        ANR2017I Administrator SERVER_CONSOLE issued command: QUERY MOUNT
        ANR2034E QUERY MOUNT: No match found using this criteria.
        adsm>
        q pro
        ANR2017I Administrator SERVER_CONSOLE issued command: QUERY PROCESS
        ANR0944E QUERY PROCESS: No active processes found.

        Thank you for your follow up in advance.

        Logan.

        Drives are all tied up by other processes or are not working...
        try a "q drives" and a "q mount" and a "q pro" to see where you
stand...
        later,
               Dwight
