We have an Ultra 140, running Solaris 2.6, Solstice Backup 5.0.1 and it
has a DLT 4700 autoloader (7 cartridge capacity). We have the drive
loaded with CompactIV tapes which supposedly yield 40GB density.
The Solstice Backup device name is /dev/rmt/1mbn.
We're trying to get the 40GB capacity but are not able to do so. The nwadmin
utility seems to indicate we're getting slightly over 20GB/tape.
We see conflicting information about the density capacity of the
DLT4700. The sun www site DLT4700 spec page says the read/write
compatibility is 20GB for a CompactIV tape. Yet, the product overview
page for the DLT4700 says the drive can store up to 280GB which is the
7*40GB/Tape figure. Which doc should we believe?
So, how do we set up Solstice Backup and the DLT4700 to give us the 40GB
capacity/CompactIV tape? Has anyone else run into this problem?
