Hiya,

We've just powered up our FAS2020 box and run through the initial CLI config. Now moved to System Manager and we're having trouble configuring the storage.

We have a dual controller model with 12x 450GB disks on RAID-DP with HS. If my understanding is correct, we lose 2 disks per controller for RAID-DP and 1 disk per controller for the spares. That should leave us with ~2.7TB of storage (6x 450GB). However, the default aggregate is over 250GB in size and it's telling us we can't create more as we don't have any disks available.

So what has happened to the other 2.5TB or so of storage?

Also, what is the recommended controller IP config for an active-active implementation? All on one subnet or all on seperate subnets? We are putting each controller port on dedicated switches.

Thanks

Cool. It means that only 8 of your disks are assigned, 4 per each controller.

If you want to have an even number of disks per controller, then you should add out of four remaining disks a couple to each controller (type "disk assign ?" in the CLI for more detailed instructions).

And in a case it is still confusing - whenever you access any of the controllers, you can mainipulate only with disks owned by it, so you have to repeat all the tasks on both controllers.

Regards,

Radek
