How to configure iSCSI TOE w/ load balancing?
Sorry guys but let me start off by saying I am an AIX noob! I am running AIX 6.1 and recently purchased two iSCSI TOE cards. The plan is to connect these two cards to a Dell EqualLogic SAN and that has two volumes configured for logs and data.
The point of the two cards is to do load balancing and fail over if one card does, obviously I am interested in making this reliable and always available.
What I have done so far is:
Configured the ics0 and ics1 to have
IP addresses on the iSCSI network with the SAN
discovery policy of file
Edited the /etc/iscsi/targetshw# to include the paths to both volumes that I have configured
Now, when I do lspv, I see four new hdisks, because each card has connected to each volume. So obviously I have duplicate connections.
What I want to do is have these two cards load balance the connection and failover if a card dies and that's where I am stuck. I have read a little on MPIO but not having much luck with iSCSI TOE.
Can anyone add any configuration advice, it would be much appreciated!!

If you have two or more servers load balancing, are the servers mirroring one another? If images, etc., are uploaded, will they be stored on all the servers so that if one server goes down, the images will be served up by another server? (1 Reply)

sndconfig
sndconfig(8) System Manager's Manual sndconfig(8)
NAME
sndconfig - configure sound card for use with Linux kernel modules
SYNOPSIS
sndconfig {--help,--noprobe,--noautoconfig}
DESCRIPTION
sndconfig sets up the necessary configuration files to use a sound card on a Red Hat system. If PnP support is compiled in, by default snd-
config will do an initial probe for PnP sound cards using the pnpdump utility. If the --noprobe option is given this step will be skipped.
The user will be notified if any cards were found. Otherwise the user must pick the card type from a menu. Then the user must choose the
I/O port, IRQ, and DMA settings for the sound card. These must be known ahead of time and depend upon the jumper settings of the sound
card. For PnP cards, the program will determine settings for the card; if the --noautoconfig option is given the user can choose the val-
ues which will be programmed into the PnP device. There is no guarantee that the values entered do not conflict with an existing non-PnP or
PnP device. The user must make sure these types of conflicts do not occur.
OPTIONS
--help Print a usage message on standard output and exit successfully.
--noprobe
No probe will be made for PnP cards, and the PnP configuration files will not be changed.
--noautoconfig
No autoconfiguration of PnP cards will be done; the user will be prompted for settings.
FILES
/etc/sysconfig/soundcard Stores current settings /etc/modules.conf Stores sound module configuration /etc/isapnp.conf Stores
PnP configuration
