The following tape drives (sorted by size/type/model/access) are available.

Access means the primary user of the computer to which the tape drive is attached. Others in the computer owner's group(s) also have access by virtue of having an account on that host.

Device names

The Solaris device name is /dev/rmt/#, where # is the unit listed above.

The single-letter density options that can follow # are: c(ompressed), h(igh), l(ow), m(edium), u(ltra compressed). Note that some options are not available on some drives.

You can then add a trailing b (for Berkeley behavior) and/or n (for no rewind) to that, which is recommended.

Example: /dev/rmt/0ubn

Cleaning tapes

For private drives, you should request a cleaning tape from the owner of the drive.

For public drives, one should be available near COMA for DAT and Mammoth drives, and near INDUS for Exabyte drives. Otherwise, you will have to go to 8370 to borrow one. (Do not forget to mark them as having been used one more time each time you run them through.)

Important information about Mammoth drives:

The Mammoth 8900 drives can write only to 170-m AME Mammoth tapes (although they can read older Exabyte tapes), which cannot be read by older drives (e.g., Exabyte 8500). Please do not try to write to older tapes on those drives or you will wear them out and accomplish nothing else.
