CPU Count Limits HP-UX 11.31 VSOE ? or Am I having iCAP issues?

I've a hand me down 'Dome (Gen2 - PA8800) - 52 CPUS in 8 Cells. I whacked the existing nPar configs. Went GENESIS and instaleld 11.31 VSOE. Added in the remaining 7 Cells so I now have 1 single nPar accross 8 Cells and 52 CPUs (cores). BUT it only sees 46 of the 52 CPUs. PARSTATUS show one Cell board as having those 6 "deconfigured" CPUS. I went to BCH and indeed they show as "deconfigured" so I went into the BCH CONfiguration menu and CPUconfigured those 6 cpus in. Rebooted the nPar again but those CPUs still show as deconfigured in PARSTATUS. Could it be we have iCAP/iCOD active on these CPUs? Are these iCAP'd/iCOD CPUs bound via a CPU id? Below I have an "icapstatus" output. I tired doing an "icapmodify -a 6" but no dice.

Anyone?

Re: CPU Count Limits HP-UX 11.31 VSOE ? or Am I having iCAP issues?

Nelson,

Did this box have iCAP on it, or are you just surmising that?

I hope it didn't as re-creating the genesis partition is specifically forbidden on systems with iCAP on them (as it wipes out the iCAP data in NVRAM)

If the system had iCAP on it, you can go and check at www.hp.com/go/icap/portal - in there you can enter the system serial number and see if it had iCAP assigned.

If it did have iCAP, you'll need to get a support call open to recreate all the iCAP data correctly

Nelson,

also you have checked that the cell board in question actually has some memory on it? The CPUs can't be used if there is no memory on the board (although I susepct it wouldn't join the partition if that were the case)

Re: CPU Count Limits HP-UX 11.31 VSOE ? or Am I having iCAP issues?

I've never had any experience with iCAP/iCOD so I would not know how to be sure if those CPUs are iCAP'd... Thats why I posted the "icapstatus" out.

Thanks

This usually means they are ICAP. You can either purchase the licenses to activate then permanently or get TiCAPs (temporary licenses). If I remenber correctly you can go to the activation site and get a free 30 day trial. NOTE: That is a total of 720 hours for all the cpus in any combo. Not 720 per cpu.

" I went into the BCH CONfiguration menu and CPUconfigured those 6 cpus in. Rebooted the nPar again but those CPUs still show as deconfigured in PARSTATUS"

You used

CPUconfig [[[ON|OFF]]] Config/Deconfig processor

right?

If you use

> in all

from main menu, what do you get?

Example:

PROCESSOR INFORMATION

Cab/ Processor
Cell Slot CPU Speed HVERSION SVERSION CVERSION State
---- ---- --- -------- -------- -------- -------- --------------
0 0/0 0 875 MHz 0x5ea0 0x0491 0x0301 Active
1 875 MHz 0x5ea0 0x0491 0x0301 Idle
2 875 MHz 0x5ea0 0x0491 0x0301 Idle
3 875 MHz 0x5ea0 0x0491 0x0301 Idle
2 0/2 0 875 MHz 0x5ea0 0x0491 0x0301 Idle
1 875 MHz 0x5ea0 0x0491 0x0301 Idle
2 875 MHz 0x5ea0 0x0491 0x0301 Idle
3 875 MHz 0x5ea0 0x0491 0x0301 Idle

Partition Total Cells: 2
Partition Total Processors: 8
Partition Active Processors: 8
Partition Deconfigured Processors: 0
...

IIRC iCAP CPUs have a unique status there.

Any related logs in GSP/MP during the boot?

Hope this helps!

Re: CPU Count Limits HP-UX 11.31 VSOE ? or Am I having iCAP issues?

Torsten,

Yes I did a CPUconfig.

Then from BCH went to OS boot. Then parstatus still showed those CPUs as deconfigured.

Dropped back to BCH. Did a CPUconfig and checked the CPUs are "configured" in not flagged to be configured on next reboot as was teh case prior the CPUconfig'ing ON.

So what I've done next was to do an RS as the message did say to perform a "hard reboot" (is going from BCH after doing a CPUconfig ON considered a hard reset?) but now all I see are just 3 Cell boards !?

IN ALL shows now just 3 Cell boards man...

Still looking at the SEL logs though

Re: CPU Count Limits HP-UX 11.31 VSOE ? or Am I having iCAP issues?

Configuring CPUs or DIMMs to enable/disable must be followed by a reset to allow the system to do the changes.

You did a "rs" or "rr"?

Was there a pending reconfiguration request?

What does the MP command "cp" return?

A full "parstatus" (attach!) would be nice now.

Hope this helps!
Regards
Torsten.

Just an RS Torsten.

But another RS fixed the issue (or should I be worried?) All Cells are now seen.


Am now booting and we'll see if I now have 52 CPUs
