Logical Drive Extension in RHEL 3

[Matthew Claridge <mclaridge rwa-net co uk>]

Hi,

Does anyone know if RHEL 3 supports logical drive extension? We have a 
Proliant ML350 server which I'm about to install some new disks in - the 
array controller will automatically expand or extend an array but 
helpfully says "not all operating systems support logical drive 
extension...blah blah blah...consult your os documentation". Red Hat's 
documentation makes no mention of it and I can't find any references to 
it on the web site either.....

cheers
Matt
