b. If the intended boot device is not correctly listed 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 partition. If the
intended boot device cannot be added to the boot list, ask the customer or system administrator to
verify that the device you are trying to boot from is assigned to the correct partition. If it is, go to
step 4.
3. If attempting to boot from the network:
a. Verify that the IP parameters are correct.
b. 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.
c. Check with the network administrator to ensure that the network is up. Also ask the network
administrator to verify the settings on the server from which you are trying to boot.
d. Check the network cabling to the adapter.
e. Restart the partition and retry the boot operation.
4. Try to boot and run standalone diagnostics against the devices in the partition, particularly against the
intended boot device. Standalone diagnostics can be run from CD-ROM or a NIM server. To boot
standalone diagnostics, follow the detailed procedures in "Loading the Standalone Diagnostics from
CD-ROM Using an HMC" on page 750 or "Running Standalone Diagnostics from a Network Installation
Management (NIM) Server" on page 752.
Attention: Standalone diagnostics may be run on systems configured for either full system partition
or partition standby. When attempting to boot diagnostics on a partition from partition standby, the
device from which you are booting standalone diagnostics must be made available to the partition that
is not able to boot, if it is not already in that partition. Contact the customer or system administrator if a
device must be moved between partitions in order to boot standalone diagnostics. If devices are
moved between partitions, both partitions must be rebooted. For more information, see "Standalone
Diagnostic Operation" on page 750.
If standalone diagnostics boot successfully:
a. Go to the Task Selection menu, and select Display Configuration and Resource List. If the
intended boot device is not listed, ask the customer or system administrator to verify that it is
assigned to the correct partition. If it is, and does not appear in the NEW RESOURCE list, go to
"MAP 0290: Missing Resource Problem Resolution" in the RS/6000 and Eserver pSeries
Diagnostic Information for Multiple Bus Systems.
b. Run diagnostics on the device you want to boot from. If an SRN, not an 8-digit error code, is
reported, go to the RS/6000 and Eserver pSeries Diagnostic Information for Multiple Bus
Systems.
c. If the diagnostics are successful, it may be necessary to perform an operating system-specific
recovery process, or reinstall the operating system.
If standalone diagnostics do not boot successfully from CD-ROM:
a. Verify that the CD-ROM drive is assigned to the correct partition.
b. Check the SCSI cabling to the CD-ROM drive. Check the power connector on the CD-ROM.
c. It is possible that another SCSI device on the same bus is causing the problem. Do the following:
1) Disconnect the power and signal cables from all other SCSI devices that are attached to the
SCSI adapter to which the CD-ROM is attached.
2) Try to boot standalone diagnostics again.
3) If you are still unable to load standalone diagnostics, go to step 5 on page 390.
4) If standalone diagnostics load, one of the disconnected devices is causing the problem.
Reconnect the devices one at a time and retry the boot operation until the problem recurs, and
replace the device that caused the problem. Go to "MAP 410: Repair Checkout" in the
RS/6000 and Eserver pSeries Diagnostic Information for Multiple Bus Systems.
If standalone diagnostics do not boot successfully from a NIM server:
a. Verify that the network adapter is assigned to the correct partition.
