iSCSI configuration question - IBM DS3300

[m1kkel84]

Hey.

I have DS3300 iSCSI model with 2 controllers.

4 vmware ESX4 hosts.

COntroller A:

POrt1 - 192.168.11.1

Port2 - 192.168.11.2

Controller B:

Port1 - 192.168.11.3

Port2 - 192.168.11.4

I have added all ip's in esx's iscsi targets, but i thought that the esx server would only use the first ip, and then use number 2 in case of failure.

But when i log into DS3300 and click iscsi, i can see that there is 16 connections. 4 from each server - that means each server have logged in to each ip.

I think this is the wrond way to configure it - ?

I also think i might be thrashing my san.

What do you think ?

As I remember, this storage is quite similar to Dell MD3000i.

You must create 2 different network with 2 different address.

Hey.

Yes it is the same as the dell MD3000i.

I've read the documents you attached, and that states nothing about what i should do regarding the 4 ethernet ports and vmware setup / preferred paths.

[m1kkel84]

by the way, i see 31 paths to my san. Should i use fixed, round robin, or ?

[AndreTheGiant]

31 paths

Sure? I think that this is the LUN ID.

Do not use round robin with you kind of storage (cause is not a active/active one).

For the IP configuration see:
