Hello,
I'm trying to help a guy out on a VMWARE server, running what looks like a cut down version of redhat? 2.4.9-vmnix2 ...
Bascially the box serves vm clients via allocating a LUN from a SAN.. to cut a long story short, I need to find out which SAN the luns are comming from (could be 1... (0 Replies)
Hi,
We recently purchased a 3 tb RAID. In the setup, it created 2 slices, one 2 tb and one 1 tb slice. Right now only the 2 tb slice is visible when booting up. I was told that the second slice needs to be mapped to a lun and a port like the first slice is.
Does anyone know how I would go... (1 Reply)
I have a list of LUN ID, my task is to find if disk has been added or not. How do I do that? I have been searching the forum and not able to find answer.

Hello all,
I have the following env:
* DS4300 storage SAN
* AIX 5.3 Lpar (storage through vio server)
* AIX 5.3 Server
Some FS are too small do I'm setting up a process to increase the size of the FS.
To expand the size of the FS I plan to do the following for the physical AIX server,... (1 Reply)
Aix 6.1, working with a nim master and nim_altmaster
both LPARS have access to the same data LUN, /nimdisk
I do realize the risks of having 2 servers access the same LUN, however it serves the purpose of being able to restore mksysb's to/from our DR site if necessary, at least in theory ;)

ioconfig
ioconfig(4) Kernel Interfaces Manual ioconfig(4)NAME
ioconfig - ioconfig entry format
SYNOPSIS DESCRIPTION
The file is used to retain information on a system's I/O configuration across reboots. It contains two types of information:
o Mappings of dynamically allocated major numbers to drivers.
o Mappings of instance numbers to hardware paths.
At boot time this file is read and the information is stored in the kernel data structure. The file is created by at install time and is
modified by and when devices are added or removed (see insf(1M), rmsf(1M), and ioscan(1M)). The only purpose of the file to maintain con-
figuration information when the system is not running. While the system is running, all accesses are made directly to the kernel struc-
ture, although any tools that change the kernel structures must also keep consistent.
There will be two copies of maintained: and A second copy is placed in because NFS diskless clients are not guaranteed to have a reliable
directory at boot time.
The file begins with the magic number.
Following the magic number is an array of structures, which logically form a tree structure defining the connectivity of the various levels
of software modules and managers, the device class and hardware address of each element, and the logical unit associated with each leaf
node. The root of the tree is array element 0.
Each contains the following fields as defined in
The definitions of each element are as follows:
Each record must have a character string as its first entry
which is used to identify the record type. The default record is the If the string begins with an underscore character then it
is one of the variants.
This is the default record entry for the ioconfig file.
The must begin with an underscore character to distinguish record from other record type.
The element is a structure that contains following elements.
This record stores information about major numbers dynamically assigned
to drivers. It is used to allow major number assignments to persist across boots. The must begin with (underscore) character to
distinguish record from other record type.
The contains following elements.
