HP EVA8000: Something to Consider Before Buying a Decommissioned EVA8000!


The HP StorageWorks 8000 Enterprise Virtual Array (EVA8000) was the largest of the three members in the EVA family (EVA4000, EVA6000, EVA8000,) and could support up to 240 disk drives of various disk sizes going up to 300GB. The product was retired on May 31st, 2008* – and is now not far off its End-of-Life date (normally 5 years from date of retirement.) *Source HP Product Bulletin

If you are considering buying a decommissioned EVA8000, the first thing you need to ask:

Does it come with licenses?

Without licenses (the EVA is licensed per TB, and the Command View management tool also needs to be licensed), WWNs with their offset codes, and if HP will not help with what would probably be an out of service unit (which is their right,) alas the EVA8000 is pretty much just scrap tin – but read on, there is one glimmer of hope.
Note: The previous owner might have upgraded to a new EVA and had the original license ported across, in which case the old unit would have absolutely no valid license anywhere.

The EVA8000 came from HP in its own cabinet, and attached to this cabinet were two labels with the WWNs and offset codes for the two HP StorageWorks HSV210 controllers. On first initialization, the installation engineer would input the WWNs and offset codes into the OCP (Operator Control Panels.)

If labels with WWNs and offset codes are not available, it should be possible to guess the WWN from querying the Fibre Channel switch from which they are plugged into, but guessing the offset code is difficult unless HP will help you (you could try manually inputting offsets {2 digit hex number} in sequence – will take a long long time though, as have to manually enter the WWN first, every time.)

One chance is if the five original Quorum disks are in place (if the unit had not been completely wiped), and the controllers can read WWNs from there. If there was any licensed storage available after being able to read WWNs from the original Quorum disks, still needs a license for Command View to manage the array with – there is a 60 day evaluation though which may just do the trick.
