Robert> I'm adding 8 DS14mkII shelves on Sunday morning. The new FC Robert> controllers are already in the Filer (FAS940 running DOT Robert> 6.5.4) and blinking away. I also slid the 8 trays in (very Robert> carefully) over the past 2 weeks and cabled the copper Robert> interconnects up in-to-out between shelves this afternoon.
Robert> Sunday morning we'll shut the Oracle DB's down and do the following:
Why not just shutdown the filer, hook up the last fibre connections between the new shelves and the filer and reboot? 4 minutes of down time....
Robert> 1. Run the Fiber cable between the FC controller A/B ports and Robert> the Fiber based DS14 shelves. (we installed 2 and are planning Robert> on putting 4 each shelves per FC controller)
Robert> 2. Run the "storage enable adapter n" command.
Robert> 3. Flip the Terminator switch on the Fiber IN ports of each of Robert> the 4 ports across the two Fiber based shelves.
Robert> Does it matter in which order I flip the terminator switch Robert> and/or run the "storage" command? Should I flip the Robert> Terminator switch off and *then* issue the "storage" command? Robert> I'm thinking Terminator switch last....
I'm not clear what you doing here, are you saying that you already have shelves on the new controllers and you want to add shelves into the loop in real time? If the controllers are completely unused, just cable them up and turn on the termination switches to the correct positions, _then_ I'd run the 'storage enable adapter' command.
To me, you don't want to enable the storage until all the hookups are done and correct. Once you do the enable command, it will go out and probe that adapter, so it should be physically all setup ahead of time.
But hey, I'm ignorant and I'd love to be educated here too.
