Background:
Sun E-450/Solaris 2.6
Netbackup 3.2
Storagetek L700 and 9740 Libraries
DLT 7000 Drives w/ 245F and 2565 microcode levels
Problem: Drives are not self cleaning using tape alert


Issue:
I recently implemented the tape alert method of cleaning on all of my master
servers. I set up barcode rules and inserted cleaning tapes as required. The
master server is aware of the cleaning tape:

Masterserver# vmquery -b -mt dlt_clean
media   media     robot  robot  robot  side/  optical  # mounts/last
ID     type      type     #    slot   face   partner  cleanings   
mount time

So I know I have the cleaning tape available and mouts are at 20 ( it's a
new tape ). Manual Cleaning works. Drive cleaning frequency is set to 0. I
keep finding tape drives with their cleaning light on ( cleaning required )
, but I don't see any cleaning occurring indicated by decremented cleaning
tape mounts. I've set VERBOSE in my vm.conf so I can see the request for
cleaning entered in the /var/adm/messages log but nothing ever comes
through? Has anyone ever seen this? Is there a command to simulate a drive
requesting a cleaning besides doing a manual cleaning? What netbackup log
would be a good place to find some hidden problem that are perhaps
preventing the cleaning? Any input would be greatly appreciated.
