I had a customer install a zBX with x86 blades last month. If you have no idea what a zBX is click here. Now this may seem like a bit of a unusual proposition - x86 blades inside an IBM mainframe - but there is a good reason for it. The business value here is that the mainframe advantages of centralized management and business continuity are extended to the x86 world (Windows and Linux), as well as AIX on POWER
We had one little hiccup along the way: the storage, an IBM DS8300, could not see the ports on the zBX. Our investigation first led us to the DS8000 involved. I thought perhaps some ports were configured as FICON only - but this turned out not to be the case.
The next route we took was to bring in some of my crack ATS colleagues John and Ken (see the ATS blog here) to see if we had set up the zBX wrong. The good news - all was well on the zBX side.
This left one culprit. Oops - we had set up the switch incorrectly, telling it to only transfer FICON data, not FCP. Once we fixed that one, we were off to the races. The moral of the story - zBX and DS8000 together are a great solution, but you have to get the end-to-end paths correct.
