Upgrading RAID

[Sean Roe]

Is there a procedure for adding more drives to a RAID system and increasing
the size of the partitions?  We have mylex Accellaraid 250's (sp?) driving
the RAID.  I am a little lost as to how to do it.  I mean when and if the
Mysql server ever breaks 10-12 gig of data I would like to have an easy way
out.

Thanks,
Sean
