sobriqueWell, as a side show to this 'ere maint work, we have sheet lightning. I do mean that we have a storm of impressiveness overhead, and making many flashes.
Nice big forked jobbies, and loud claps of thunder. Lovely.
Have lost power here once, but that just meant a reboot and reconnect to the server (the computer room is on a flywheel+generator UPS, but the office isn't).
Unfortunately, it's looking like our data transfer isn't going so well. About 20Gb/hour. (which'd put it clear of 20 hours to complete)
I've had better than that off a flippin' tape, so I'm not impressed.
Minor disasters so far, include discovering that our entire batch of fiber cables are crossovers. (You virtually never do this, as ... well you have a transmit and a receive fiber. You don't usually want to transmit down the same fiber as the other machine is transmitting down.
Finding that our brocade switches only have half the ports active due to licenses. (Plugged into a working port, because CBA to go license key hunting tonight)
Found out that the multipathing software that we use, isn't compatible with the latest emulex HBA driver. (oops crashy crashy).
And then found some monkey has stolen one of my switch IP addresses, so rather than talking to a brocade, and failing to log in, I was in fact talking to a cisco network switch.
Grr.
However, since this is looking like being a 20+ hour job, it's very very likely that it'll be this weekend instead.
Which is nice.
