Adding a second iSCSI storage repository?

In addition to all of the other changes that are planned for our 3-node cluster: I'd like to add a second iSCSI storage repository to our 3-node cluster. The cluster members will access the second SR using a pair of NIC's (configured independently of one another so that MPIO may be employed).

  1. How should I go about adding+configuring the new dual-port NIC's to the cluster members?
  2. How should I go about adding+configuring the new SR to the cluster?

TIA,

    Hi,

    I assume that you already have a pair of NIC for each host and you want to add second iSCSI on different network.

    1.Create a new storage network

    2.Discover the new san server

    3.Create new repository

    Adding the dual-port NIC was much easier than I expected!

    Working one-host-at-a-time:

    1. I used the OVS Manager to...

      1. place the host into "Maintenance Mode";
      2. shut the host down completely;

    1. I added the new dual-port NIC to the host and I turned the host back on.

    1. And then I used OVS Manager to...

      1. configure each of the two new interfaces with static IP addresses (From the "Servers & VMs" tab; using the "Ethernet ports" perspective, and then; "Edit" the NIC);
      2. take the host out of "Maintenance Mode".

    1. And then I followed @Daniele Bocciolini's instructions (above) to configure the new SR.

    Super easy!

    There was one very important detail about this deceptively simple procedure that deserves mention.

    During the SAN Discovery phase, at the final step (i.e., "Manage Access Group"):

    1. Edit the default Access Group;
    2. select the "Storage Initiators" tab, and;
    3. add at least one host to the list of storage initiators.

    HTH,
