Sharepools
Check if
your pseries is multiple shared_pools capable :
# lssyscfg -r sys -m [managed_system]
-Factive_lpar_share_idle_procs_capable
–>
returns 1 if it supports multiple shared_pools, and 0 if not .
List the
sharepools active on the frame and the lpars associated with’em :
# lshwres -r procpool -m [managed_system]
-Fname,lpar_names
DefaultPool,"VIO1,VIO2"
shp_oracle,"my_db_lpar1,my_db_lpar2"
shp_app,"my_app_lpar"
Changing
the current sharepool for a LPAR :
# chhwres -r procpool -m [managed_system] -o s -p
[lpar_name] -a
"shared_proc_pool_name=[target_sharepool_name]"
Changing
the sharepool defined in a LPAR’s
profile :
# chsyscfg -r prof -m [managed_system] -i
"lpar_name=[lpar_name],name=[profile_name],shared_proc_pool_name=[target_sharepool_name]"

/!\ (in
order to do this, you need to execute the « awk |sort|uniq » part from an AIX
system, because you can’t use awk with hscroot on a HMC ( I really should ask
IBM why, one day… ?! it is so useful…))

• on my beautiful p795, I have 21 empty
slots, 24 NPIV-capable Fibre channel adapter, 17 SAS controllers and 38 FcoE
cards
• If you wish to have more thorough
information (like physical location), you juste have to remove the « awk
|sort|uniq » part, which will give this kind of output (much more verbose,
please note the « null » value which gives us the unassigned I/O Cards):

Shutting
down a LPAR:
# chsysstate -m [managed_system] -r
lpar -n [lpar_name] -o shutdown [--immed]
rename a lpar (easy):
# chsyscfg -m [managed_system] -r lpar -i
"name=my_lpar_name,new_name=my_new_lpar_name"
