array reconfiguration
At the current time, all files on volume F can be deleted as they are backups of files in other places on my network. The other volume (E) contains approximately 55GB of data that I need available on the new volume. These files are backed up on tape.
I have been reading the Array Configuration Utility User Guide, but I am not sure which path is the shortest to get done what I want to do. Can you give me some recommendations on how best to proceed?
Should I expand and migrate? Can this be done in one step?
or,
Should I delete both logical drives, create a new drive and reload the data from my backup?
What kind of time frame am I looking atr to accomplish this?

Re: array reconfiguration
The easiest way and probably the fastest is to delete array B and C, and recreate as Array B and restore the data.
If you did not want to restore the data, you can just delete C and "expand" the B array with the 2 newly available drives. The process can take a short while and it depends on how much space is currently being used on the array and how much i/o is going on. After the expansion, you can (or should be able to) migrate the logical drive to RAID5 and then recreate the 3rd logical drive if you still need it.
If you need more space on the data drive after the migration to RAID5, you can then "extend" the logical drive. You would have to then extend the filesystem via the OS. Assuming you are running Windows, you can use diskpart.exe to perform the extension. If this is the route you are going to take, let me know and I will post more about diskpart.

Re: array reconfiguration
Yes.
Keep in mind that you can mix RAID1+0 and RAID5 in the same array. The array is not "set" as either, Logical Drives IN the array are set to a RAID level.

Re: array reconfiguration
Wait, hold up. I though you had 3 separate ARRAY's.
Do you have 1 Array with 3 logical drives?
If so, the you can just delete logical drive 2 and 3, then create a new logical drive, raid5 with the available space.
Both logical drives would use ALL 6 drives.

Re: array reconfiguration
Yes.
"How long should I expect it to take for the delete and create?"
Minutes, if not seconds.
"How long do you think the format will take?"
Quick format = seconds
Regular format = depends on size, but probably minutes
