StorageWorks 8505 8mm Cartridge Tape Drive

C.2.2.2 Dump Parameters for the Tape Drive

The parameters that should be used when running the dump utility with the SWXTE tape drive are:

density = 54000 (BPI)

size = 6000 (112 meter tape) in 8200 mode

size = 13000 (112 meter tape) in 8500 or 8500c mode

blocking factor = 126

Example 1

The following example shows backing-up the entire disk partition onto the SWXTE tape drive:

dump 0dsbf 54000 13000 126 /dev/rst20 /dev/sd0g

Example 2

The following example shows backing-up the "/usr" partition on disk sd2g onto the SWXTE tape drive assigned as "rst4", in the low-density mode. The following would be useful if you want to read the tape in an EXB-8200 drive which uses the size (s) of 6000.

dump 0dsbf 54000 6000 126 /dev/rst4 /dev/sd2g

For further help, refer to the man pages of dump.
