I am trying to generate a report to track dlpar operation performed on a MS and was wondering if anyone has done this before.
I can get history from HMC using lssvcevents , but this does not give me details as to what quantity was added or removed .
Any thoughts ?
Thanks (3 Replies)

Hi all,
is any of you using RMC for monitoring your LPARs? Is it viable?
I know the IBM Magazine article and the Redbooks about it but I would like to hear from first hand.
Thanks in advance for sharing your experience! (7 Replies)

There can be configurations in IBM Server wherein a

Or
A VIOS - VIOC LPARs created.
Now in both cases they are lpars. But if I want to differentiate b/w a standalone LPAR vs an VIOC LPAR how can I do..?

Hey All,
I have running dual VIOS on a P9 systems, and just created a new LPAR profile. My objective is to create LPAR Client VFC adapters, and then DLPAR VFC Server adapters on the VIOS.

IO(4) BSD Kernel Interfaces Manual IO(4)
NAME
io -- I/O privilege file
SYNOPSIS
device io
#include <sys/types.h>
#include <sys/ioctl.h>
#include <dev/io/iodev.h>
#include <machine/iodev.h>
struct iodev_pio_req {
u_int access;
u_int port;
u_int width;
u_int val;
};
DESCRIPTION
The special file /dev/io is a controlled security hole that allows a process to gain I/O privileges (which are normally reserved for kernel-
internal code). This can be useful in order to write userland programs that handle some hardware directly.
The usual operations on the device are to open it via the open(2) interface and to send I/O requests to the file descriptor using the
ioctl(2) syscall.
The ioctl(2) requests available for /dev/io are mostly platform dependent, but there are also some in common between all of them. The
IODEV_PIO is used by all the architectures in order to request that an I/O operation be performed. It takes a 'struct iodev_pio_req' argu-
ment that must be previously setup.
The access member specifies the type of operation requested. It may be:
IODEV_PIO_READ The operation is an "in" type. A value will be read from the specified port (retrieved from the port member) and the result
will be stored in the val member.
IODEV_PIO_WRITE The operation is a "out" type. The value will be fetched from the val member and will be written out to the specified port
(defined as the port member).
Finally, the width member specifies the size of the operand to be read/written, expressed in bytes.
In addition to any file access permissions on /dev/io, the kernel enforces that only the super-user may open this device.
LEGACY
The /dev/io interface used to be very i386 specific and worked differently. The initial implementation simply raised the IOPL of the current
thread when open(2) was called on the device. This behaviour is retained in the current implementation as legacy support for both i386 and
amd64 architectures.
