If you use the "autoclean" feature it will cause Netbackup to down drives
that are being cleaned by the library. That's why we are converting to
Netbackup automated cleaning. If you talk to Storagetek about an unusual
rate of drives being downed they will first ask you if you are using
Storagetek autocleaning and Netbackup software. If so you will get an
unusually high rate of drives being downed because Netbackup doesn't know
when STK is cleaning the drives. Converting to Netbackup cleaning will help
you resolve this problem. Thanks,

Craig

                Hi ,

I suggest you to implement the "autoclean" feature on the StK's library.

This is the better way to ensure you that a drive cleaning is done.

Hth , bye.

Fabrice

It says if a tape drive needs cleaning.

If you are using SSO, time based cleaning
doesn't work quite well, and still
you will need to check libraries sometimes.

Simple script, ssh to robot host and
tpclean command should help your operators to
handle this on daily basis.

Thanks,
