I've got functioning SBS 2008 server running on an HP Proliant dl360 G4p.
My question is regarding the best way to ensure I provide a quick recovery time objective. In other words I want to (in the event of a HDD disaster) be able to get the server back up and running from a backup as qick as possibel.
Background info which might help:
Server has 2 x 146GB 15k RPM U320 disks mirrored using the HP Smartstart disk at install time. So hardware raid configured outside the OS.
SBS 2008 being backed up via the native new backup service (incremental daily) to an external USB2 300GB HDD.
2 X 146GB 10K RPM U320 disks (off ebay) standing by and waiting as secondaries for impending doom's day scenario.
Crux of the question:
Basically my recovery strategy (in theory) is to at regular intervals (say quaterly) power the server down, remove the primary disks, replace with the secondaries. Power the server backup and boot from the DVD (SBS disk1) and complete a bare metal restore alla Nickolas King's handy little article:
Where I'm a little hazy/concerned is how the HP hardware mirroring (raid) side of things would work. Specifically I'm worried that if I remove the primary disks and replace with the secondaries, the mirrored, logical disk created by the HP hardware prior to the OS having anything to do with things might be in some way changed/replaced.
Do any of you with more experience restoring from failed disk type scenarios on HP DLs have some light to shed on this. Is my plan valid or would I end up with (possibly a valid restore to the secondary disks) but unusable primary disks?
