We are looking at running MPIO for it's redundancy and load balancing benefits. Does anyone know what pieces of software or modules are needed on the VIO server to get load balancing to work. Remember we are using EMC's DMX3500 storage system. We no longer want to use Powerpath. :rolleyes: ... (2 Replies)
Hello everyone!
Could anybody help me how to configure a set of disk? From our existing EMC storage, we still have spaces for a new set of disk. I know how to replace a deffective disk but never had experience in setting/replacing a new pair of disk (M1 and M2). My objective here is to increase... (1 Reply)
This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)

Hi All..
On to a new implementation with AIX 7.1 san boot from EMC disks (Using NPIV). Anyone played with this recently?
Wondering if we need PowerPath on the AIX clients or has native MPIO matured to replace it. Thoughts?
Thanks

VND(4) BSD Kernel Interfaces Manual VND(4)NAME
vnd -- vnode disk driver
SYNOPSIS
pseudo-device vnd
options VND_COMPRESSION
DESCRIPTION
The vnd driver provides a disk-like interface to a file. This is useful for a variety of applications, including swap files and building
miniroot or floppy disk images.
This document assumes that you're familiar with how to generate kernels, how to properly configure disks and pseudo-devices in a kernel con-
figuration file.
In order to compile in support for the vnd, you must add a line similar to the following to your kernel configuration file:
pseudo-device vnd # vnode disk driver
To also compile in support for reading compressed disk images, add the following option to your kernel config file:
options VND_COMPRESSION # compressed vnd(4)
Compressed disk images are expected in the cloop2 format, they can be created from "normal" disk images by the vndcompress(1) program.
There is a run-time utility that is used for configuring both compressed and uncompressed vnds. See vnconfig(8) for more information.
FILES
/dev/{,r}vnd* vnd device special files.
SEE ALSO config(1), vndcompress(1), MAKEDEV(8), fsck(8), mount(8), newfs(8), vnconfig(8)HISTORY
The vnode disk driver was originally written at the University of Utah. The compression handling is based on code by Cliff Wright
<cliff@snipe444.org>.
BUGS
The vnd driver does not work if the file does not reside in a local filesystem.
The vnd driver does not work if the file is sparse.
