XenServer iSCSI SAN Setup/Config

There are 2 ways to setup iSCSI SAN connections in XenServer. Via cli or gui.

Create Bonded connection

1. Click your Pool
2. Click a Host
3. Click NICs tab
4. Click Create Bond
5. Add NICs
6. Create
7. I then recommend going to Network and naming the bond that shows something understandable

GUI Method

1. Click Server drop down then Management Interfaces
2. Click New Interface at the bottom
3. Name the MI and select the Network NIC
4. Enter IP information

CLI Method

1. Open the cli for the server needing connection to the iSCSI SAN
2. Type "xe pif-list" to get the uuid of the pif you want to alter (note that eth0 is listed at the bottom)
3. xe pif-reconfigure-ip mode=Static uuid=(enter uuid) ip=IPaddresshere setmask=255.255.255.0
4. xe pif-param-set disallow-unplug=true uuid=(enter uuid)
5. xe pif-param-set other-config:management_purpose="Storage" uuid=(enter uuid)
6. At this point you should be able to ping an iSCSI storage node from the server console
7. Don't make the same mistake I did... remember to give the server node access permissions within your SAN management interface so that it can discover the Target IQN. To find the IQN of the node type simply open the server node properties. On the General tab it is listed at the bottom. Change it to a desired IQN.
8. Click Storage and select iSCSI
9. Type in the IP of the Storage server target host
10. Click discover IQNs then discover LUNs. Click Finish. Note that you will want to ensure that you have exported your VI server prior to connecting to any existing VI LUNs as it will format the disk for XenServer use.

At this point I went on to import the converted VI server onto the disk. Note that initial attempts to import a 19.99GB export onto a 20GB disk failed saying that their wasn't enough space. To get around this I edited the volume to have an additional .5GB. Less than this would have likely been sufficient. I then followed the import steps from Virtual Iron > Citrix XenServer Conversion to successfully import the VM.
