completing system startup tests, see Table 13–7.
Table 13–7 Startup Without Booting
Possible Cause Corrective Action
The default startup action
environment variable is set to
halt at the console. Change default startup action as
Chapter 10 describes.
Software is not installed. Install the system software. Refer
to the software documentation for
installation instructions.
Incorrect boot device was
specified. Change the default boot device
bootdef_dev environment variable,
explained in Chapter 10.
Boot device is not properly
configured. Enter a show device command as
described in the next section, and check
to see that all devices are configured
properly. If not, check the SCSI
ID numbers and SCSI cables, also
described in that chapter.
The scsi_reset variable is
not properly set.
Set scsi_reset to 4 to allow the SCSI
devices enough time to recover from a
SCSI bus reset.

variable is
not properly set.
Set
boot_reset
to ON so that
firmware will initialize the kernel
hardware and any TURBOchannel
devices.
Software problem. Check your operating system
documentation for information or call
your Digital service representative.
The boot_osflags variable

Consult your operating system
documentation.
