StorEdge T3 and T3+ Array (Partner-Group) SAN Considerations

This section contains information for using StorEdge T3/T3+ arrays in a partner-group configuration as the storage devices in a SAN that is in a Sun Cluster environment.

Full, detailed hardware and software installation and configuration instructions for creating and maintaining a SAN are described in the Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide, Sun SAN 3.0 that is shipped with your switch hardware. Use the cluster-specific procedures in this chapter for installing and maintaining StorEdge T3/T3+ arrays in your cluster; refer to the Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide, Sun SAN 3.0 for switch and SAN instructions and information on such topics as switch ports and zoning, and required software and firmware

Hardware components of a SAN include Fibre Channel switches, Fibre Channel host adapters, and storage devices and enclosures. The software components include drivers bundled with the operating system, firmware for the switches, management tools for the switches and storage devices, volume managers, if needed, and other administration tools.

StorEdge T3/T3+ Array (Partner-Group) Supported SAN Features

Table 9-3 lists the SAN features that are supported with the StorEdge T3/T3+ array in a partner-group configuration. See the Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide, Sun SAN 3.0 for details about these features.

Table 9-3 StorEdge T3/T3+ Array (Partner-Group) Supported SAN Features

Feature	Supported
Cascading	Yes
Zone type	SL zone, nameserver zone*    *When using nameserver zones, the host must be connected to the F-port on the switch; the StorEdge T3/T3+ array must be connected to the TL port of the switch.
Maximum number of arrays per SL zone	8
Maximum initiators per LUN	2
Maximum initiators per zone	4*    *Each node has one path to each of the arrays in the partner-group.

Sample StorEdge T3/T3+ Array (Partner-Group) SAN Configuration

Figure 9-5 shows a sample SAN hardware configuration when using two hosts and four StorEdge T3/T3+ partner-groups. See the Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide, Sun SAN 3.0 for details.

StorEdge T3/T3+ Array (Partner-Group) 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, do not connect the cables to the replacement switch until after you recall the Fabric configuration to the replacement switch. For more information about saving and recalling switch configurations see the Sun StorEdge Network FC Switch-8 and Switch-16 Installation and Configuration Guide, Sun SAN 3.0.
