8Configuring Directors
This chapter provides procedures specific to HP StorageWorks Director models.
Changing a Director’s name
HP recommends that you customize the enterprise-class platform name for each platform. Some system logs
identify devices by platform names, if you assign meaningful platform names, logs are more useful.
To change the platform name:
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the chassisName command using the following syntax:
switch:admin> chassisname "newname"
where newname is the new name for the enterprise-class platform.
Enterprise-class platform names can be from 1 to 15 characters long, must begin with a letter, and can
contain letters, numbers, or the underscore character. It is not necessary to use the quotation marks.
3. Record the new platform name for future reference.
Identifying ports
Because Directors contain interchangeable port blades, their procedures differ from those for fixed-port
switches. For example, fixed-port models identify ports by domain, port number, while Director models
identify ports by slot/port number.
The HP StorageWorks 4/256 Director integrates 10 slots that contain control processor, port, and
application (AP) blades:
• Slot numbers 5 and 6 contain control processor blades (CPs).
• Slot numbers 1 through 4 and 7 through 10 contain port and AP blades.
The HP StorageWorks DC SAN Backbone Director (short name, DC Director) integrates 12 slots that
contain control processor, core, port, and AP blades:
• Slot numbers 6 and 7 contain control processor blades (CPs).
• Slot numbers 5 and 8 contain core blades.
• Slot numbers 1 through 4 and 9 through 12 contain port and AP blades.
NOTE: CPs contain communication ports for system management, and are used for low-level,
chassis-wide tasks. In the 4/256 Director, CPs are used for intra-chassis switching.
Core blades are used for intra-chassis switching as well as interconnecting two DC Director chassis.
Port blades are used for host, storage, and interswitch connections.
AP blades are used for Fibre Channel Application Services and Routing Services, iSCSI bridging, FCIP,
and storage virtualization.
On each port blade, a particular port must be represented by both slot number and port number.
When you have port blades with different port counts in the same Director (for example, 16-port blades
and 32-port blades, or 16-port blades and 18-port blades with 16 FC ports and 2 GbE ports, or 16-port
and 48-port blades), the area IDs no longer match the port numbers.
