SCSI Utility
Notes
Follow these guidelines about the SCSI utilities:
Never run a SCSI utility on the Host ID (ID = 6).
An error mnemonic of SCSI_E_type indicates you cannot
perform the utility on the specified device, for example,
running the tape key utility on a fixed disk.
On the formatter and erase utilities, you must type OK at
the DKAxxx OK prompt, or an error appears.
An error occurs if an invalid device ID and logical unit
number (always 0) are entered. Type SHOW DEVICE from
the console prompt for the correct IDs.
If a drive is not listed in the SHOW DEVICE table, verify the
SCSI and power connections, and ensure that there are no
duplicate device IDs.
See Appendix A for SCSI Utilities Error Messages.
TURBOchannel
Adapter
Utilities
The MIPS/REX emulator utility executes TURBOchannel option
firmware. The emulator functions as follows:
Each MIPS instruction that would normally be executed by
a MIPS processor passes through the emulator software and
executes.
REX callback routines that would normally be provided by
the DECstation console are either mapped one-to-one to
their VAXstation console equivalents, or support routines
are added where functions differ from those provided in the
VAXstation computer.
Allows the execution of canned tests and utilities for specific
TURBOchannel options as if the user were sitting in front of
a DECstation computer.
