Operating Systems AIX How to configure iSCSI TOE w/ load balancing? Post 302750259 by cbrinker on Monday 31st of December 2012 09:29:05 AM

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!!

NAME
fish -- play ``Go Fish'' SYNOPSIS
fish [-p] DESCRIPTION
fish is the game ``Go Fish'', a traditional children's card game. The computer deals the player and itself seven cards, and places the rest of the deck face-down (figuratively). The object of the game is to collect ``books'', or all of the members of a single rank. For example, collecting four 2's would give the player a ``book of 2's''. The options are as follows: -p Professional mode. The computer makes a random decision as to who gets to start the game, and then the computer and player take turns asking each other for cards of a specified rank. If the asked player has any cards of the requested rank, they give them up to the asking player. A player must have at least one of the cards of the rank they request in their hand. When a player asks for a rank of which the other player has no cards, the asker is told to ``Go Fish!''. Then, the asker draws a card from the non-dealt cards. If they draw the card they asked for, they con- tinue their turn, asking for more ranks from the other player. Otherwise, the other player gets a turn. When a player completes a book, either by getting cards from the other player or drawing from the deck, they set those cards aside and the rank is no longer in play. The game ends when either player no longer has any cards in their hand. The player with the most books wins. fish provides instructions as to what input it accepts. BUGS
