Yeah, as I dig into this it becomes more complicated.
We have a number of pools:
Disk Pools:
diskpool
Sequential Access Storage Pools:
ltopool
8mmpool1 (which needs to die)
archivepool
ltoarchive
reclaimpool
Copy Storage pools:
copypool
ltocopy
We have several devclasses, too:
Disk Device Class
Disk
File Device Class
ReclaimClass
8MM Device Clases
8mmclass1
LTO Device Class
LTO
The 8mm stuff really needs to go away, I think, especially since
Treefrog we had was traded in to get the T50.
We also have data that is archived on the LTO tapes, and that we'll
need for at least 4 more years - financial stuff, doncha know.
