Yes, that worked. Now I run into another problem... I want to increase the parity drive to a larger size and upgrade most of the old 1TB data disks, so I did the following:
1) un-share all the existing disks that I want to remove;
2) run New Configuration;
3) un-assign the disks that I want to remove;
4) replace all the disks except for the 2 that I wanted to keep;
5) reboot.
So I basically just kept 1 data disk, and the original parity disk. All the other disks are new, i.e., they have not been pre-cleared (which was I planning to do via the Web GUI). The system started, and I can use telnet to login, but I got no GUI, not sure what to do next... Your assistance is much appreciated.
Here is the diagnostics file for your information.
