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 tape and network boot attempts. If booting from CDROM or tape,
watch for activity on the drive's LED indicator. A blinking LED means that the loading
of either the boot image or additional information required by the operating system
being booted is still in progess. If the checkpoint is displayed for an extended period
of time and the drive LED is not indicating any activity there may 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 still attempts to boot and 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 installed and a Diagnostics
CD-ROM is available.
1. Restart the system and get to the Firmware SMS Main Menu. Select Multiboot.
Check if the intended boot device is correctly specified in the boot sequence.
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 intended boot
device cannot be added to the boot sequence go to step 3).
Remove all removable media from devices in the boot list from which you do
not want to boot.
If attempting to boot from the network go to step 2.
If attempting to boot from a disk drive or CD-ROM go to step 3.
2. If attempting to boot from the network:
Verify that IP parameters are correct.
Attempt to "Ping" the target server using the SMS "Ping" utility. If the ping is
successful, have network administrator verify the server configuration for this
client.
Turn power Off, then On and retry the boot operation.
Check network cabling to adapter.
3. Try to boot and run standalone diagnostics against the system, particularly
against the intended boot device.
If the intended boot device is not listed in the "NEW RESOURCE" list go to
"MAP 0290: Missing Resource Problem Resolution" in the Diagnostics
Information for Multiple Bus Systems.
If a SRN, not an 8-digit error code, is reported, go to the Diagnostics
Information for Multiple Bus Systems manual.
