Trouble with tape changer

Hi all. If you think you might be able to help me get Amanda working with a Sun server and tapechanger, please read on and let me know what you think. I inhereted a project to configure Amanda to back up a Sun E6500 with an attached StorEdge 30-slot changer, which includes two Quantum DLT

Multi-tape question

Hi, all. I managed to get my changer working with Amanda using chg-scsi. Today I started the first test dump to see what would happen. Using hardware compression, my DLT-IV tapes hold about 70 GB. I set up a dump of several large and small partitions totalling ~88 GB. One was not mounted for

Resolved - Multi-tape question

Thank you to those that wrote back yesterday, especially Don. I used the non-compressed device (in this case, /dev/rmt/1n), and amanda did indeed write filesystems until it hit EOT and rewrote that specific interrupted filesystem to the next tape. Does anyone here have a changer working with
