| If the partition boot process stops at SMS, ensure you do not get any LED codes that indicate that no boot device was found. If the bootlist is not properly set or no boot device is found, the lpar will stop at SMS.
If you are able to select X to exit SMS and the boot process continues normally without having to select the boot device, there are some more things you can check.
1. Check that the partition's Boot Mode is set to Normal.
On the HMC V7 HMC, select the partition and go to Properties. In the settings tab, check that Boot Mode is not set to SMS. If it is set to SMS, you will need to bring down the partition and reactivate it with a profile that has boot mode set to Normal.
2. Check that the Multiboot Option is set to OFF in SMS
- Activate the partition in SMS and open a vterm.
- In the Main Menu, select #5 "Select Boot Options"
- Check #3 "Multiboot Startup". It should be set to OFF
3. Check that keylock position is not set to Manual
Select the managed system that has the partition you are working on and select Properties.
In the Power-On Parameters tab, make sure the Current Keylock position is not Manual. If so, set the Next Keylock position to Normal. Unfortunately, this will require the entire managed system be power cycled for the change to take effect.
4. For p5 systems, check the parent adapter of the boot disk and its adapter microcode
The following Ultra320 SCSI Adapter microcode levels have selection time-out problems w/ HUS10K DASD. This may cause a boot drive not to be seen during the boot process which would cause the system to boot to SMS.
|CCIN/Feature Code||Microcode version||Adapter description|
|5702/1974||05080064||Dual Channel Ultra320 SCSI Adapter|
|5703/1975||05090066||Dual Channel Ultra320 SCSI RAID Adptr|
|5709/1976||050D0067 ||SCSI RAID Enablement Card|
|2780 ||050E0064 ||Quad Channel Ultra320 SCSI RAID Adptr|
|573D/1908||05110048 ||SCSI RAID Enablement Card|
|570A/570B||050A0064 ||Dual Channel Ultra320 SCSI Integrated|
|573E||05100047 ||Dual Channel SCSI Integrated Cntrllr|
|NOTE:CCIN 573E includes the following part numbers which were built with this problem SCSI microcode:|
9115-505 10N6679, 10N6688, 10N6696
If you have the Ultra320 SCSI Adapter at the microcode level listed above, you will need to update to the latest available microcode level for your given adapter or integrated controller. This will prevent occurance of the issue.
Since the adapters contain the boot disks, a Diagnostic CD and an ISO image CD containing the microcode image can be used to download microcode to an adapter in a system that will not boot to AIX/Linux. Instructions are contained in the various microcode READMEs.
