Connecting storage expansion enclosures to the DS4200 Express
In the initial installation of the DS4200 Express, you can add only new storage
expansion enclosures to the DS4200 Express Storage Subsystem. This means that
there must be no existing configuration information on the storage expansion
enclosures that you want to install. Also, only EXP420 storage expansion
enclosures are supported in a DS4200 Express configuration.
If the storage expansion enclosures that you want to install currently contain logical
drives or configured hot spares, and you want them to be part of the DS4200
Express Storage Subsystem configuration, refer to the IBM System Storage
DS4000 Hard Drive and Storage Expansion Enclosure Installation and Migration
Guide. Improper drive migration might cause loss of configuration and other storage
subsystem problems. Contact your IBM technical support representative for
additional information.

Attention
Before powering on the DS4200 Express Storage Subsystem, it must be
populated with at least two drives. If at least two drives are not installed in
each attached storage expansion enclosure or DS4200 Express Storage
Subsystem, when you power on the DS4200 Express and its attached storage
expansion enclosures, your standard storage partition key might be lost and
must be regenerated using instructions on the IBM DS4000 Solutions and
Premium Features Web site:
https://www-912.ibm.com/PremiumFeatures/
In addition, the resulting insufficient load to the enclosure power supplies
might cause them to intermittently appear as failed, falsely indicating the
power supplies are bad. All drives in the DS4200 Express Storage Subsystem
and the connected storage expansion enclosure or enclosures must contain
no prior configuration data.
