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)
Hi
I would like to ask what the benefits are of changing from RDAC to MPIO when connecting to a DS4000 on AIX 5.3? I have heard that IBM MPIO "might" support more than 1 active path to a LUN when connecting to a DS4800 through more than 1 host connection on the same AIX client. I understand that... (8 Replies)
Hi folks,
does anybody have a link to a documentation how to implement native MPIO on AIX? We are using EMC PowerPath and Datacore SanSymphony/Cambex for this so far and I wasn't able to find a good description on that topic. All I know so far is that mkpath, chpath and lspath are used to... (3 Replies)
If PATH is set to ../bin:../sbin:/usr/bin:/usr/local/bin (chunk of path string). Sometime when I try to execute ls command it says ../bin/ls not found. According to my understanding "ls" should be searched in all the path varibales that we set in the PATH varaibale.
Is there any reason for the... (5 Replies)

Hi,
I was trying to uninstall the native MPIO driver on the AIX 6.1 machine we have in our lab and ran into a whole bunch dependent filesets initially. I deleted the disks, fcsX, fscsiX, fcnetX and tried again, but ran into the same error.
Subsequently, I figured out that the OS disks in... (4 Replies)

lsdev - list device drivers in the system
SYNOPSIS
driver | class] block_major] char_major] major] [major ...]
DESCRIPTION
The command lists, one pair per line, the major device numbers and driver names of device drivers configured into the system and available
for invocation via special files. A in either the block or character column means that a major number does not exist for that type.
If no arguments are specified, lists all drivers configured into the system.
If the option is specified, will not print a heading. This option may be useful when the output of will be used by another program.
The and options are used to select specific device drivers for output. If more than one option is specified, all drivers that match the
criteria specified by those options will be listed. These search options are divided into two types: name search keys (the and options)
and major number search keys (the and options). If both types of options are present, only entries that match both types are printed. The
same type of option may appear more than once on the command line with each occurrence providing an ORing effect of that search type. The
and options may not be specified at the same time.
The ability to process major arguments is provided for compatibility and functions like the option.
Options
List device drivers that match
class.
List device drivers with the name
driver.
List device drivers with a block major number of
block_major.
List device drivers with a character major number of
char_major.
List device drivers with either a character
major number or block major equal to major.
DIAGNOSTICS
The and options may not be specified at the same time.
A major number is malformed or out of range.
EXAMPLES
To output entries for all drivers in the class:
To output entries that are in the class that have either a block or character major number of
To get the character major number of into a shell environment variable:
WARNINGS
Some device drivers available from the system may be intended for use by other drivers. Attempting to use them directly from a special
file may produce unexpected results.
A driver may be listed even when the hardware requiring the driver is not present. Attempts to access a driver without the corresponding
hardware will fail.
only lists drivers that are configured into the currently executing kernel. For a complete list of available drivers, please run (see
sam(1M).
DEPENDENCIES
Since relies on the device driver information provided in a routine, may not list drivers installed by other means.
