[Chapter11]

It would help if you'd tell us what the environment is, and you've done so far to resolve it. Otherwise the obvious problems are documented already:

Probable Causes
ARRAY CONTROLLER
CABLES AND CONNECTIONS
ARRAY DASD MEDIA

Failure Causes
DASD MEDIA
ARRAY CONTROLLER
CABLES AND CONNECTIONS

Check out your cabling, and that you're not trying to use a defective media.

I would agree with Chapter11 Comment!

Check the connectivity first and then check your zoning for changes (Back to Chapter11 comment we should know what have you changed lately!?!)
