Cpu details needed

Hi Experts,

Its an rp8420, and 2 partitions, napr0, npar1
ioscan -k |grep -n processor |wc -l
6
=====================================

[Cabinet]
Cabinet I/O Bulk Power Backplane
Blowers Fans Supplies Power Boards
OK/ OK/ OK/ OK/
Cab Failed/ Failed/ Failed/ Failed/
Num Cabinet Type N Status N Status N Status N Status MP
=== ============ ========= ========= ========== ============ ======
0 4 cell slot 21/0/N+ 6/0/N+ 5/0/N+ - Active
8 I/O expansio 4/0/N+ 6/0/N+ 1/0/N - Backup
==============================================

[Virtual Partition Resource Summary]
CPU Num Memory (MB)
CPU Bound/ IO # Ranges/
Virtual Partition Name Min/Max Unbound devs Total MB Total MB
============================== ================ ==== ====================
hut3 2/ 6 2 2 12 0/ 0 12288

Can you explain what is CPU Min/Max?
CPU bound/unbound ?

Thanks

You can either use, machinfo OR /opt/ignite/bin/print_manifest.

Re: Cpu details needed

CPU Min/Max is ... minimum available CPU to the partition and Maximum available CPU to the partition.

CPU bound/unbound, read this thread.

Re: Cpu details needed

while running vparcreate you would (together with other resources) assign the min. and max. Nos. of CPUs to the vpar,
which appear as bound (i.e. eq min) and unbound
(i.e. num - min)
e.g.

vparcreate -p vptest -a cpu::4 -a cpu:::2:4 -a cpu:1/14 -a cpu:1/15 ...

The syntax for CPU allocation with vparcreate
is:

vparcreate -ppartition_name [-a cpu::total] \
[-a cpu:::[min][:[max]]]] \
[[-acpu:hw_path]...]

Bound CPUs are dedicated to a vPar and can't be dynamically removed or added to vPars. Bound CPUs handle I/O interrupts and should therefore be used with I/O-intensive applications. Unbound CPUs can be dynamically added and removed from vPars. Unbound CPUs do not handle I/O interrups and should be used for CPU intensive applications."

Re: Cpu details needed

for CPU movement across npar I would suggest to read Mark`s quotes on this thread (just a suggestion)

http://h30499.www3.hp.com/t5/Workload-Resource-Management/Control-CPUs-between-npars-and-vpars/m-p/5081681#M3861

Re: Cpu details needed

Try

# parstatus

# vparstatus -v

# vparstatus -A -v

and attach the output.

Hope this helps!

Torsten.

Re: Cpu details needed

Experts,

i got the solution by executing the CSTM> sel dev
and seein the used CPU & total no of CPU

thanks
