Better yet, saw this in the Star biz section print version (not found in the online version)

I'll try to recap as much as I can the chrnology of events (newspaper in me boss office at the moment but you can pick up the Star print version and check it out yourself)

6.00 am the hard disk died, hard disk replaced
6.30 am replacement hard disk causing problems, and triggering failure in another hard disk and the CPU
8.30 am activate the backup system
1.00 pm backup system start up took too long, switch back to production site to reattempt.
from then onwards, connection problems bla bla bla

Question time. Hard disk problematic causing failure in another hard disk and the CPU??

Second question. Only one failover system? That's it?
