Trying to set up a new iSCSI IBM DS3300. I think I have the cabling correct, but I'm getting confused about which IP to pick when I start to map the hosts to the LUNs. I am (obviously) new to this.
Here's the picture:
SAN has 2 mgmt ports, 2 controllers on each port. I have an HBA controller card in the management server and I'm trying to connect a test server to the drive I created on the array to test before I move some critical data onto the SAN.
So:
Set IP for QLogic NIC on Mgmt Server to 10.10.2.20
Set IP for Management (Ethernet) Controller A to 10.10.2.21
Set IP for Management (Ethernet) Controller B to 10.10.2.22
Set IP for ISCI Controller A Port 1 to 10.10.4.101
Set IP for ISCI Controller B Port 1 to 10.10.4.102
Set IP for ISCI Controller A Port 2 to 10.10.5.101
Set IP for ISCI Controller B Port 2 to 10.10.5.102
Did the IPs this way because IBM suggests different subnets done in this manner.
Connected HBA card on mgmt server to unmanaged switch. Connected SAN mgmt ports and iSCSI controllers to the same switch.
Conigured array with RAID, etc., and created one 300 GB LUN.
Installed iSCI initiator software on test server (with multipath software) and confiured it to connect to IP 10.10.4.101, logged on, etc.
When I go into disk management on the test server, it sees a new drive, but only sees 20 MB. Have I picked the wrong IP? Or is there another step I'm missing with the SAN management software? Do I need to setup the host there as well?
Thanks for any help, including pointers to learning tools. I do have the IBM red book for this SAN, and I'm slogging through it, but it can be confusing about which host is which, if you know what I mean, and I'm really unsure as to whether I should be connecting the host targets to the SAN mgmt IP addresses, or the iSCSI controller port IP addresses.
