we have a used FAS2220 with 12x600 and NFS licence
It is installed using 7-mode
We'd like to use it for NFS storage purpose, using ESX for tests and maximizing capacity.
We erased it using boot menu, choice 4
We used to use "System Setup" but here we have a problem after setting up first screen with network setup a weird message telling "unable to reboot NAME-OF-CONTROLLER" on controller 1 (but in fact it reboots !). Then system setup won't go further.
I wanted to go further to be able to configure the filer in active/passive mode where all disks are in one aggregate (i never did it but i remember that there is this choice into "system setup")
By the way, if you have no idea about what is the "system setup" problem, can you tell me how i can achieve this using CLI ?
Yes, it's possible to turn HA Pair into single node controller.
It's your choice, if this is for personal use then you probably don't care about HA or sinlge point of failure.
If you need HA functionality with maximum storage capacity: 1) Controller1 - Assign all disks here 2) Controller2 - Assign just 3 disk (For root aggregatre) But you lose : 3 disks for controller2 root aggr.
Non-HA Single node controller: Controller1 : Assign all disk shelfs in a sinlge loop. Like you mentioned, you can use raid-4, and have single aggregate with 11disks (10 data + 1 Parity) and 1 spare.
