StorageWorks 8505 8mm Cartridge Tape Drive
C–4 Order Number: EK–STWCT–UG. E01
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
