SSA disk configurations

[<James> <healy>]

I know this isn't exactly a TSM Question but...

Anyone have an idea where I can find documentation baout replaceing a
failed drive in a SSA disk configuration.
The documentation I've found tells you you need to logically remove the
data adn drive first, unfortunately we've phjysically removed the drive and
now the subsystem won't allow us to remove it logically.

Thanks in advance
Jim
