Connecting storage expansion enclosures to the DS3200

Attention

Before you power-on the storage subsystem, it must contain at least four drives. If at least four drives are not installed in each attached storage expansion enclosure and in the DS3200 storage subsystem, when you power-on the DS3200 and its attached storage expansion enclosures, your standard storage partition key might be lost and must be regenerated, using instructions at http://www.ibm.com/storage/fasttkeys/.

In addition, the resulting insufficient load to the enclosure power supplies might cause them to intermittently appear to have failed, falsely indicating that the power supplies are bad. All drives in the DS3200 storage subsystem and the connected storage expansion enclosure or enclosures must contain no prior configuration data.

In the initial installation of the DS3200, you can add only new storage expansion enclosures to the DS3200 storage subsystem. This means that there must be no existing configuration information about the storage expansion enclosures that you want to install.

Note: In this document, EXP3000 storage expansion enclosures are used as examples in text and illustrations.

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 DS3200 storage subsystem configuration, see the IBM DS3000 Storage Manager Version 2 Installation and Support Guide, which is in the Documentation folder on the IBM
