Apologies for this newbie question. We have inherited an IBM p5 520 (9111-520) running AIX 6.1.0.0 which seems to be the base install and no further patches installed.
Is this vulnerable to the Spectre/Meltdown threat?
Are patches available?
Looks like AIX 6.1.0.0 went 'end of support' in... (8 Replies)

Hello all, I am hoping someone can point me in the right direction here.
We had a machine running AIX 6.1 that someone completely corrupted, so we decided to re-load it from media. I was able to boot into DVD media, select options for complete (destructive) install, AIX standard, etc. The... (0 Replies)

I have a power5 that I would like to update and bring everything forward.
I am wondering about trouble-free upgrades. Is it better to go 5.3 -> 7 or 5.3 ->6 ->7?
The power5 box is behind and hopefully can learn from experiences here.
Thanks. (6 Replies)

Hi,
I have written an application which reports the CPU information like user cpu%, sys cpu%, idle cpu% and wait cpu%. The application is built on an AIX 5.1 machine. The appliaction runs fine on AIX 5.1 and 5.2 and their results match with that of the topas command. But when I run the... (1 Reply)

assign_cpu_to_pset(3) Library Functions Manual assign_cpu_to_pset(3)
NAME
assign_cpu_to_pset - Assigns a processor to a processor set
LIBRARY
Pset Library (libpset.a)
Mach Library (libmach.a)
SYNOPSIS
#include <sys/types.h> #include <sys/processor.h>
int assign_cpu_to_pset(
unsigned long cpu,
long pset_id ,
long option );
PARAMETERS
Processor or processors to assign to the specified processor set. Processor set identifier, which is returned by the create_pset function.
Specifies a bit mask. Currently, only the ANY_CPU bit is supported. If this bit is set, the value specified by the cpu variable is the
number of processors to be assigned to the specified processor set from the default processor set. If the ANY_CPU bit is not set, the
value specified by the cpu variable is the mask of processors to be assigned to the processor set.
DESCRIPTION
The assign_cpu_to_pset function removes processors from their current processor set and assigns them to the processor set specified by the
pset_id variable. This function requires root privileges.
If the ANY_CPU option is specified, the number of processors specified by the cpu variable are assigned from the default processor set to
the processor set that is specified with the pset_id variable. If the specified number of processors are not available in the default pro-
cessor set, an error is returned and no processors are assigned.
If the ANY_CPU option is not set, the value specified by the cpu variable is a mask of processors to be assigned to the specified processor
set. For example, if you specify a cpu value of 6, then processors 2 and 3 are assigned to the processor set.
Note that processors are not required to start in slot 0 on some platforms. For example, you may see a three-processor system with proces-
sors in slots 6, 7, and 8. The console assigns the master processor at power up, which is usually the processor in slot 0 if it is occu-
pied. However, there is no requirement that slot 0 must be populated or that the master is the first processor on the bus. In the example
of the three-processor (slots 6, 7, and 8) system, the master processor will be the one in slot 6.
Processor assignments are logged in the /var/adm/wtmp file.
RETURN VALUES
If the processor assignment is successful, the assign_cpu_to_pset function returns zero (0). If the assignment is unsuccessful, the func-
tion returns a negative number. Use the print_pset_error function to print a message that describes the error.
