While you can update the controller firmware with the web interface, I chose not to do this as HPe provides a Windows executable that will connect to the management interface and update both controllers.Even though I didn’t have the unit configured yet, it’s a very interesting process that occurs.It’s a well known fact that to enable i SCSI on the unit, you have to have the controllers running the latest firmware version.Turning on the unit, I noticed the management NIC on the controllers quickly grabbed an IP from my DHCP server.This is how we got started with the HPe MSA 2040 SAN (formerly known as the HP MSA 2040 SAN), specifically as fully loaded HPe MSA 2040 Dual Controller SAN unit.For the server, we just purchased another HPe Proliant DL360p Gen8 (with 2 X 10 Core Processors, and 128Gb of RAM, exact same as our existing server), however I won’t be getting that in to this blog post.In the last few months, my company (Digitally Accurate Inc.) and our sister company (Wagner Consulting Services), have been working on a number of new cool projects.As a result of this, we needed to purchase more servers, and implement an enterprise grade SAN.
I configured all the host ports for i SCSI and set the applicable IP addresses that I created in my SAN topology document in the above paragraph.
When you do this and configure all the software properly (VMWare in my case), you can create a configuration that allows load balancing and fault tolerance.
Keep in mind that in the Active/Active design of the MSA 2040, a controller has ownership of their configured v Disk.
You can do live controller firmware updates with a Dual Controller MSA 2040 (as in no downtime).
The way this works is, the firmware update utility first updates Controller A.
