How much time it usually takes to create a DR plan?

Hi,
In your opinion, how much time would be a reasonable amount of time for a
DBA to spend on the creation of a DR plan for a set of two MS SQL Server 2000
databases (OSes, and so on...) - one production and one standby, without
using replication, log shipping, or cluster, but only SAN storage block level
synchronization?
-- Hoping this makes any sense Oskar.You omitted almost all DR elements from the list :)
It depends on your environment. You just did not add your list Database
Mirroring however this is not applicable in SQL Server 2000 already.
So, what kind of a DR is this? A Cold-Standby? Like Backup\Restore or
Attach\Detach?

document the procedures.
Once this is established, ongoing maintenance should be minimal.

unit", or both of them go bust I switch to the remaining "processing unit"
and "storage unit". If that doesn't work (e.g. because of some kind of
"logical", "non-storage-level" fault that couldn't be detected) I recover
from the last full DB backup + the chain of transaction log backups up to the
point of corruption for affected areas.

performed the tests to have the info for your paper work. If you are just
talking about creating a plan for doing the DR tests, we are talking about
hours or at most days.
