Changing the Default Fast SCSI (fast_scsi_a)(fast_scsi_b)
Available
Settings
You can set the
fast_scsi_a
and
fast_scsi_b
environment
variables to on or off:
• on to operate in slow and fast SCSI mode, device dependent.
• off to operate in slow SCSI mode.
Default Settings
The environment variable default settings are: on for
fast_scsi_a
and off for
fast_scsi_b
. Thus the external
SCSI controller will be initialized to operate in slow SCSI mode,
and the internal SCSI controller in fast SCSI mode.
Command
Example
To set the
fast_scsi_a
and
fast_scsi_b
environment variables,
enter the appropriate command. The system responds as shown.
>>> set fast_scsi_a
on
Return
FAST_SCSI_A = ON
>>>
Using the on parameter changes the default setting.
