Delayed on account of bad cables. Two of the three short-wave fibre cables connecting the future storage servers to the fibre-channel SAN ended up bad. On one I can see light, so the return-leg is broken. The other gave me the amber light on the switch, which usually means either one channel is working or the pairs are swapped; as this is a prebuilt cable swapped-pairs is unlikely.

We had a spare cable available which greatly helped in proving the broken cable problem. But it also means that only two of the three future storage servers is able to be clusterable.

I have to assume that installation killed the cables. And we didn't do the install. Aie. Fragile stuff, fibre.
