We just completed building Unity 4.2(1) on an MCS 7825-I2 and we were adding the latest patches. After one of the patches installed, the system rebooted. The system had problem rebooting (would not proceed past the screen that says press F1 for Start Up Menu or F12 for Boot Menu). After a number of attempts (both power cycling and CTRL-ALT-DEL's) the server reboot. However, at the login prompt we also received a pop-up notifying us that a number of services did not start.
Further investigation shows that the RAID Array has been split into two separate yet identical physical devices.
We now have the following logical drives:
C: - same as original C:
D: - identical to C: but on other physical volume
F: - same as original D:
G: - same as F: but n other physical volume.
How do we repair this RAID array so that we again have drives C: and D: on a single logical volume?
