Adding Storage Arrays

To add a storage array to MD Storage Manager, click New in the Array Selector area. A window is displayed that allows you to choose the automatic or manual process to add a new storage array.

NOTE: Verify that your host or management station network configuration— including station IP address, subnet mask, and default gateway—is correct before adding a new storage array using the Automatic option.

NOTE: For Linux, set the default gateway so that broadcast packets are sent to 255.255.255.255. For Red Hat® Linux®, if no gateway exists on the network, set the default gateway to the IP address of the NIC.

NOTE: MD Storage Manager uses TCP/UDP port 2463 for communication to the MD Storage Array.

Automatic Discovery of Storage Arrays

The Automatic Discovery process sends out a broadcast message across the local subnetwork (subnet) and adds any storage array that responds to the message. The Automatic Discovery process finds both in-band and out-of- band storage arrays.

Manual Addition of a Storage Array

Use Manual Addition if the storage array resides outside of the local subnet. This process requires specific identification information to manually add a storage array:

•To add a storage array that uses in-band management, specify the host name or IP address of the host.

When adding a storage array using in-band management with iSCSI, a session must first be established between the initiator on the host server and the storage array. For more information, see "Configuring iSCSI" in the Modular Disk 3000i Systems Installation Guide.

The host agent must be restarted before in-band management communication can be established. See "Starting or Restarting the Host- Agent Software in Windows" on page 28 or "Starting or Restarting the Host-Agent Software in Linux" on page 28.
