HP P4000: Setup a two-node cluster

December 6, 2010 — 5 Comments

This post will outline the necessary steps to create a standard (no-multisite) HP P4000 cluster with two nodes. Creating a two-node cluster is a very similar process as the one-node cluster described in my first post about P4000 systems.

The cluster is composed by:

  • 2 HP P4000 Virtual Storage Appliances
  • 1 HP P4000 Failover Manager

The Failover Manager, or FOM, is a specialized version of the SAN/iQ software. It runs as a virtual appliance in VMware, thought the most common situation is to run it in a ESX/ESXi servers running it under VMware player or Server is also supported.

The FOM integrates into a management group as a real manager and is intended only to provide quorum to the cluster, one of its main purposes is to provide quorum in Multi-site clusters. I decided to use it in this post to provide an example as real as possible.

To setup this cluster I used virtual machines inside VMware Workstation, but the same design can also be created with physical servers and P4000 storage systems.

From the Getting started screen launch the clusters wizard.

VJM-P4000

Select the two P4000 storage systems and enter the name of the Management Group

During the group creation will ask to create a cluster, choose the two nodes as members of the cluster, will add the FOM later, and assign a name to the cluster.

Next assign a virtual IP address to the cluster.

Enter the administrative level credentials for the cluster.

Finally the wizard will ask if you want to create volumes in the cluster, I didn’t take that option and finished the cluster creation process. You can also add the volumes later as I described in one of my previous posts.

Now the that cluster is formed we are going to add the Failover Manager.

It’s is important that the FOM requires the same configuration as any VSA as I depicted in my first post about the P4000 storage systems.

In the Central Management Console right-click into the FOM and select Add to existing management group.

Select the management group and click Add.

With this operation the cluster configuration is done. If everything went well in the end you should have something like this.

    Hi,

    I have configured in a manner similar to that write in this post. But I detect that if you configure it this way, it does not failover.

    If you turn off a node, you lose connectivity to the volumes. Do you know how to configure it correctly?

    Regards,

    Thanks for the writeup. It worked great for me. I had to put the networking portion of the FOM VM in the VmPlayer in bridged mode so it would be in the same ip range.

    Hello,

    I installed two ESXi5 in a cluster, each one with a VSA configured as RAID 10 with a FOM on a 3rd server.
    Everything works great, BUT….
    After rebooting a server or both the iSCSI does not reconnect to the VSA VIP and I have to manually “rescan” for databases. (waited for two hours…)
    I’m quite sure this is not supposed to be like that….
    Have you encountered this or can assist?

    Thank very you very much in advance!

    P.S
    I really enjoy and learn a lot from you site. Keep on the good work.

      Hope this helps:
      Run the following command on the server running cmc “sc.exe config lanmanserver depend= MSiSCSI” this will ensure that the server service which provides file sharing will wait until MSiSCSI service is is completely initialized. This can be done for SQL and exchange servers as well that require explicit access to ISCSI

    my company was needing Vsa 54 fillable form this month and found a great service with lots of sample forms . If people need to fill out Vsa 54 fillable form too , here’s a https://goo.gl/QAZ4zi.
