SAN Considerations

This section contains information about how to use storage array in a SAN. This information is specific to a SAN in a Sun Cluster environment. Use the cluster-specific procedures in this chapter to install and maintain a storage array in your cluster.

For instructions about how to create and maintain a SAN, see the documentation that shipped with your switch hardware. For information on switch ports, zoning, and required software and firmware, also see the documentation that shipped with your switch hardware.

SAN hardware includes the following components.

• FC switches

• FC host adapters

• Storage devices

• Enclosures

SAN software includes the following components.

• Drivers that are packaged with the operating system

• Firmware for the switches

• Management tools for the switches and storage devices

• Volume management software

• Other administration tools

SAN Clustering Considerations

If you are replacing an FC switch and you intend to save the switch IP configuration for restoration to the replacement switch, wait to connect the cables to the replacement switch. Connect the cables to the replacement switch after you recall the Fabric configuration to the replacement switch. For more information about how to save and recall switch configurations, see the documentation that shipped with your switch hardware.
