Brocade 8Gb SAN Switch for HP BladeSystem c-Class - Configuring
Configuring the 8Gb SAN Switch
The 8Gb SAN Switch must be configured to ensure correct operation within a network and fabric. For instructions about configuring the switch to operate in a fabric containing switches from other vendors, refer to HP StorageWorks SAN Design reference guide .
Items required for configuration
The following items are required for configuring and connecting the 8Gb SAN Switch for use in a network and fabric:
Connect to the command line interface
Make an Ethernet connection and log in to the 8Gb SAN Switch:
Setting the date and time
The date and time are used for logging events. 8Gb SAN Switch operation does not depend on the date and time; a switch with an incorrect date and time value will function properly.
To set the date and time using the CLI:
Fri Jan 29 17:01:48 UTC 2000
switch:admin> date 0227123003
Thu Feb 27 12:30:00 UTC 2003
For details about changing time zones, see the tsTimeZone command in the latest version of the Fabric OS command reference guide.
Verifying installed licenses
To determine the type of licensing included with your 8Gb SAN Switch, enter licenseshow at the command prompt, as in the following example:
NOTE: For more information about the CLI, refer to the latest version of the Fabric OS command reference guide.
Modifying the FC domain ID (optional)
If desired, you can modify the FC domain ID. The default FC domain ID is domain 1. If the 8Gb SAN Switch is not powered on until after it is connected to the fabric, and the default FC domain ID is already in use, the domain ID for the new switch is automatically reset to a unique value. If the switch is connected to the fabric after is has been powered on and the default domain ID is already in use, the fabric segments.
Enter fabricshow to determine the domain IDs that are currently in use. The maximum number of domains with which the 8Gb SAN Switch communicates is determined by this switch's fabric license.
To modify the domain ID:
Disabling and enabling a switch
By default, the switch is enabled after power on and after the diagnostics and switch initialization routines complete. You can disable and re-enable the switch as necessary.
Disabling and enabling a port
Using Dynamic Ports On Demand (DPOD)
DPOD functionality does not require a predefined assignment of ports. Port assignment is determined by the total number of ports in use as well as the number of purchased ports.
In summary, the DPOD feature simplifies port management by:
To initiate DPOD, use the licensePort command
NOTE: For the Brocade 8Gb SAN Switch, DPOD works only if the server blade is installed with an HBA present. A server blade that does not have a functioning HBA will not be treated as an active link for the purpose of initial POD port assignment.
Use the licensePort command to manage dynamic POD assignments with the following options:
The following shows examples of the licensePort -show command for a Brocade 8/12 SAN Switch and a Brocade 8/24 SAN Switch:
Figure 1: Example 1
Figure 2: Example 2
NOTE: The DPOD feature does not consider disabled ports as candidates for license assignments. You can persistently disable an otherwise withble port to cause it not to come online and preserve a license assignment for future use.
Verifying the configuration
After setting initial parameters, verify the configuration as follows:
Backing up the configuration
To back up the switch configuration to an FTP server, enter configupload and follow the prompts. The configupload command copies the switch configuration to the server, making it available for downloading to a replacement switch, if necessary.
