Boot Problems/Concerns
Depending on the boot device, a checkpoint may be displayed on the operator panel for
an extended period of time while the boot image is retrieved from the device. This is
particularly true for tape and network boot attempts. If booting from CD-ROM or tape,
watch for activity on the drive’s LED indicator. A blinking LED indicates that the loading
of either the boot image or additional information required by the operating system
being booted is still in progress. If the checkpoint is displayed for an extended period of
time and the drive LED is not indicating any activity, there might be a problem loading
the boot image from the device.
Note: For network boot attempts, if the system is not connected to an active network or
if the target server is inaccessible (this can also result from incorrect IP
parameters being supplied), the system will still attempt to boot. Because
time-out durations are necessarily long to accommodate retries, the system may
appear to be hung.
This procedure assumes that a CD-ROM drive is connected to the internal IDE
connector and a diagnostic CD-ROM is available. Booting from CD-ROM or NIM on the
diagnostics image is referred to as Standalone Diagnostics.
Step 1
Restart the system and access the firmware SMS Main Menu. Select Multiboot.
1. Check to see if the intended boot device is correctly specified in the boot list. If it is
in the boot list:
a. Remove all removable media from devices in the boot list from which you do not
want to boot.
b. If attempting to boot from the network, go to “Step 2”.
c. If attempting to boot from a disk drive or CD-ROM, go to “Step 3” on page 107.
2. If the intended boot device is not correctly identified in the boot sequence, add it to
the boot sequence using the SMS menus. If the device can be added to the boot
sequence, reboot the system. If the intended boot device cannot be added to the
boot list, go to “Step 3” on page 107.
Step 2
If attempting to boot from the network:
1. Verify that IP parameters are correct.
2. Attempt to
″
ping
″
the target server using the SMS Ping utility. If the ping is not
successful, have the network administrator verify the server configuration for this
client.
3. Check with the network administrator to ensure that the network is up.
4. Check the network cabling to the adapter.
5. Turn the power off, then on and retry the boot operation.
