RE: Disk Failure -- MIDRANGE-L

Dare,

I was wrong.  I've just pulled out my old V3R7 system manual.  "The 9406
models 500, 510, and 530 support concurrent maintenance of all internal
disk units in either RAID-5 protection or mirrored mode."

I apologize for my earlier misleading posts.

Regards,
Andy
