Hi,

During initial Booting stage system doing following steps
1)It will search for bootable device,then it will ask enter the bootable path
2)After that enter into Main Menu stage.
Manin Menu>bo
Interact with IPL>Y
IPL>hpux
then it shows bottom line FLT CBF0

I'd like to know how to solve this problem and also what is FLT.

Hi,
Take a look at this post : http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0xe7c1119c3420d411b66300108302854d,00.html

Hope this helps (although it does not look good),

FLT means a FauLT has occoured during bootup and/or hardware test.

CFB0 (the FauLT code) means a High Priority Machine Check (HPMC) has happened. This points to a probable hardware problem (CPU, Cache, Memory or I/O Subsystem). Call your HP Response Center for further troubleshooting if the problem resists.

I had the same problem. Do you hgave any external storage connected, if yes, then disconnect it. Then boot your computer. Stop at the prompt and boot with IPL. type

IPL> hpux -is

This will take you to the single user. Shut your computer down and attach everything. Then reboot normally.

Good Luck.

Hi,

Do not spend to much time trouble shooting here !
Probably a HW error !
Systemboard ? --> hopefully not !

FLT CBF0 means HPMC handlinh initiated.

As you may know a HPMC = High Priority Machine Check.
Means most of the time a HW issue !

Hi Venkat:

FLT CBF0 is an HPMC error code generated by the system. If you want a better explanation about which part, what error, then check the PIM information under Service Menu in the boot console menu. This is normally a hardware error. I would suggest you to contact the hardware support.

Also, does the system shows some error while booting ( before getting the console display )? What do you mean by system checking for bootable device ? Normally the system will start booting from the primary boot disk !

Hi,

If you have an external disk connected, and since then the problem of occasionally reboots started occurring, then you will need to investigate on the crash dump.
This you will find in /var/adm/crash.

These should be send to HP or you will have to know your way with q4 to debug the real problem.

Hi Venkat:

If you suspect the external disk, then remove it and try booting again. Is it a disk array ? What type of array ? While you remove the external disk, terminate it properly if needed.

Hi Venkat:

Is it a single disk ? which model ? Did you terminate the SCSI bus after removing the disk ? Did you check the PIM information ?

[venkat_7]

it is not a single disk..it's multi pack array..i did disconnect diskarray..still is not coming up..still it shows FLT message

Hi Venkat:

You need to contact the hardware support. They will have better tools to analyze the cause of the problem. You can check the PIM information in the mean time.

Access your HPMC data and post them here, though I doubt anyone will be able to de-cypher it, you best bet is call HP response center. Ok to access the HPMC data ..

1) Interrupt the bootup to get to Service Menu.
2) At main menu prompt enter "service"
3) In the Service Menu enter "pim 0" for processor 1 or "pim 1" for processor 1, this gives you the data you need to troubleshoot.

Hi still is not coming up..NOW it shows FLT 12BF message..i can't enter in to single user mode..when i switch ON the system after couple of mins it shows FLT message..

Venkat,

Call - HP - hopefully you have a support contract?

[S.K. Chan]

FLT 1xBF (where x=cpu number)
This error comes out to be "slave CPU halted due to catastrophic boot failure". Will need to know what is your server model to determine the accuracy of the fault message.

Hi Venkat,
Just a quick tip please check the SCSI terminators on your machine's back plane as well as on the back of any external disk drives.....
