Activating Cores

Anubhav Dhingra — Thu, 13 Aug 2009 08:26:35 GMT

Hi
We have a new rx8640 server with 2 nPars.
Each nPar has 4 * Dual Core1.6 Ghz Montavale Processors. So, i should see 8 cores in machinfo. However i could only see 5 logical processors. EFI shows all the 16 threads as hyperthreading is activated on the machine.
We also have Gicap rights for sharing.
How should i activate this cores, is it through GiCap or gWLEM

Please post the output of 'icod_stat' - it will show your iCAP Licences and how many CPUs are avaible for activating.

To activate it use the command icod_modify -s for permanent activation, icod_modify -t -s for temporary activation.

If you use GiCAP you need to check if there are licences in the pool the machine belongs to and all activating must be done on the GiCAP Manager (usually a separate box).

We have enough Gicap sharing rights i.e. 3 per nPar. Do i need to have seperate box for Group Manager. I have download the code word and group file to the same machine.
icapmanage -s

I am unable to add a member...

people mucking around with iCAP and GiCAP without being sure what they are doing is a risky business, as mistakes can cost money!

my advice:

step away from the keyboard and thoroughly read the iCAP manual available here:

http://docs.hp.com/en/B9073-90201/B9073-90201.pdf

make sure you understand the concepts and implementation throroughly before returning to your problem.

If you still can't figure out what's going on, or are not prepared to invest the time in reading the manual, I suggest you get a qualified consultant in to help you setup your iCAP/GiCAP configuration.

I'm afraid but Duncan is right.

>> Additional cores that can be activated with current usage rights: 0

Please get in contact with your local HP partner or HP representative to setup the GiCAP enviroment, at this point it is not a simple task to activate the CPU's.

No, this server should not be the GiCAP manager, it should be a separate box.
You then need to get the rules file from the portal and install that onto the GiCAP server, then you need to create the relevant codeword for THAT server to be able to set up useage rights.

As Duncan says, be VERY careful here.

melvyn burnard — Thu, 13 Aug 2009 12:48:58 GMT

and with the version of iCAP you have, use the new commands, icapstatus and not icod_status

Thanx every one for the help.
