Greetings all... I've got an environmental issue that I was hoping
someone might be able to help shed some light on.
The environment is HP-UX Master/Media Servers. Switches are McData
4500's, IBM 3494 libraries with a mixture of 3590 and 3592 drives. We're
running Netbackup 5.1 MP4.
We get a routine occurrence where the drives (both types) will just go
down, both SSO and dedicated. If they're upped, they'll run fine again.
We can't find a reason for them to just go down in any of the HP/IBM/NBU
logs.  Drive cleaning is managed by the IBM 3494 Library Manager.
Has anyone else seen this in their environments? Where might we look to
get some ideas?  We have "X" number of drives and have to manually
intervene to up "Y" number of drives/day.
