If you use the autoraid as Ldev 1 there is same more things to remember.
Ldev 1 LUN may not be more then 4 Gb. Also it is recomennded that
Ldev 1 is Raid 1 (mirror). That means that the hole autoraid shall be raid
1 as you can not splitt. Thats for performance reason.
Controller 2 is not used as it looks like but it's not true. It mirror
everything
that controller 1 have in its memory so if controller 1 fails number 2 will
flush
the cache to keep good files.
