HP P2000 iSCSI MSA setup?

Hello

I've just received a HP P2000 G3 MSA (SAN), with iSCSI.  I've never worked with iSCSI before, and no setup guide is provided.  Have taken a look around the web but have failed to find anything useful.

I'm connecting this to a HP DL380GL running Win2k8 R2, running Hyper-V, with the aim of having the VM's running on the MSA (and using failover clustering with a second DL380)

Can anyone provide assistance in setting up the MSA?

thanks,

To be honest i've not used the MSA with ISCSI before, but have used Equallogic SANs.
You should be able to make a volume and enable ISCSI for this volume/LUN. Then you can just connect using the ISCSI initiator for hyper-v / 2008.

Please note that you should never access the same LUN with more then 1 machine(if it's ntfs that is)

I've just connected the server to a switch, and the MSA to the same switch.  I've run the HP discovery tool, but it fails to find the device.  I assumed the ports would get an IP from DHCP as per normal? Perhaps I'm wrong?

Just noticed one of the power supplies has an amber error light.  Will replace the PSU before proceeding! (tomorrow)

We work with MSA's quite a bit! I am assuming you have dual controllers with 2 ports each! You will need to configure the MSA with management IP's and Host IP's. Are you planning on having multi pathing for redundancy?
In which case, you may need 2 swithces to connect to it! Following would be recommended.

C = Controller, P = POrt, S = switch, H = Host
C1P1 -> S1P1
C1P2 -> S2P1
C2P1 -> S2P2
C2P2 -> S1P2

H1P1 -> S1P3
H1P2 -> S2P3
H2P1 -> S2P4
H2P2 -> S1P4

Above would be my recommended way to configure a dual controller SAN to 2 swtiches and 2 hosts.

Depending on the server generation, I think G6 onwards, all onboard NIC's are hardware ISCSI enabled and VMware will be able to see them as iscsi nic's

For MSA, you have to configure the Host and management IP's, configure volumes, configure hosts and you can either explicitly assing luns/volumes to hosts or have it open.
You will have to copy the WWN names from the hosts ISCSI and add them as hosts within the MSA cabinet. You can then assign the LUNs/Volumes to their respective hosts.

It's actually dual controller with 4 ports on each.

At the moment, I have 2 servers (G7's) connected to a gigabit switch.  Port #1 from controller 1 and 2 are also connected to the same switch.

I've run the HP discovery tool, but it fails to find the MSA.   I've checked my DHCP server as well - there doesnt seem to be any IP's assigned.

Am I missing something?

You first need to configure the ip addresser the controller ports. I am assuming htis switch is seperate from your network. this switch should be used for iscsi traffic only and you should have your lan with a dhcp server.
Connect the management ports from the MSA on your local network. the autodiscovery should hten be able to detect.

The ports on the controller are for iscsi . you need to have the management port ocnnected to your network.
once you discover the ip address, login and configure the ip addresses for the controller ports

I think let's take a step back and understand how you are trying to configure? How many switches do you have on your network, and are you planning on having a seperate switch for iscsi traffic?
In an ideal setup, following would be how it is set up:
Your normal network that connects your LAN (Clients, servers etc)
This network is where you plugin your MSA management ports, so you can access the MSA from your network.
Ideally have 2 seperate switches for your iSCSI traffic. Lets work on the below concepts:
Host 1 - 4 Physical NIC Ports
Host 2 - 4 Physical NIC Ports
Switch 1 - iSCSI Traffic
Switch 2 - iSCSI Traffic
LAN Switches
MSA
Management Port
Controller 1 - Port 1 to Port 4
Controller 2 - Port 1 to Port 4

Follow below to setup 2 switches for your iSCSI traffic and create multi pathing.
C = Controller, P = Port, S = switch, H = Host
C1P1 -> S1P1
C1P2 -> S2P1
C2P1 -> S2P2
C2P2 -> S1P2

H1P1 -> S1P3
H1P2 -> S2P3
H2P1 -> S2P4
H2P2 -> S1P4

Connect the management port from the MSA and Ports 3 & 4 from each host to your LAN switches. This ensures communication for network traffic and access your MSA thorugh the management IP address.

The controller ports will have a different IP address for iSCSI network.

I think lets start with gathering information for your network, in terms of your LAN and how many switche syou have to be able to create an iSCSI network.
