Boot Problems

Table 8–5 describes how to troubleshoot problems that occur while the system is booting
operating system software.
Table 8–5: Troubleshooting Boot Problems
Symptom
The system cannot find the boot
device.
Troubleshooting Your System
Action
Verify that your system recognizes the boot device,
using the show device command.
Check that the boot device environment variable
correctly identifies the boot device:
Digital UNIX and OpenVMS Alpha: use the show
bootdef_dev command to display the boot device.
Windows NT: Select the ARC console menu option
"Display Hardware configuration" and "Set Default
Environment Variables."
Check system configuration for the correct environment
variable settings:
For Digital UNIX and OpenVMS Alpha, examine the
auto_action bootdef_dev,boot_osflags,
and os_type environment variables. Make sure that
the bus_probe_algorithm environment variable is set to
"new. "
For problems booting over a network, check the
ew*0_protocols or er*0_protocols
environment variable settings: Systems booting from a
Digital UNIX server should be set to bootp; systems
booting from an OpenVMS Alpha server should be set
to mop.
For Windows NT, examine the FWSEARCHPATH,
AUTOLOAD, and COUNTDOWN environment
variables.
