Appendix C Product Notes for Sun™

At this time the tape is configured in the /dev directory with "rst" (rewind on close) and "nrst" (no rewind on close) format. For example, if the target SCSI ID for the SWXTE is 4, then "rst" will be "rst4, rst12, rst20, rst28"; nrst will be "nrst4, nrst12, nrst20, and nrst28".

∙rst4 and nrst4 correspond to the 0x14 density mode (8200, uncompressed format)

∙rst12 and nrst12 correspond to the 0x90 density mode (8200c, compressed format)

∙rst20 and nrst20 correspond to the 0x15 density mode (8500, uncompressed format)

∙rst28 and nrst28 correspond to the 0x8C density mode (8500c, compressed format)

•To test the SWXTE drive, back-up the file “passwd” file to tape using the “tar” command as follows:

tar cvf /dev/rst4

/etc/passwd

The system responds with:

a /etc/passwd

1 blocks

Note that depending on the size of the file, a different number of blocks may be reported.

‘Verify that the “ passwd” file was saved to tape using the following command: tar tvf /dev/rst4

The system responds with:

/etc/passwd

The installation and verification procedure is now complete.

C.2.2 Information

C.2.2.1 Operation with SPARC Server 4/470 and 4/490

The tape drive will operate normally on SPARCserver™ 4/470 and 4/490 running SunOS 4.1.2 with the following limitations:

∙There is no way to mode-select the drive to write in low-density (2.0 GB format) mode.

∙The tape drive will automatically write in high-density (5.0 format) mode from any position on new media or media previously written in low-density mode.

∙The tape drive will automatically write in low-density mode from anywhere other than the beginning of tape or media that has been previously written in low-density mode.
