Configuring the Product NOTE: If the product is attached to a fabric element, the product and fabric element must be set to the same E_D_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric. d. Choose from the Switch Priority drop-down list to set the product priority. Available selections are Default, Principal, and Never Principal. The default setting is Default. This value designates the fabric's principal switch. The principal switch is assigned a priority of 1 and controls the allocation and distribution of domain IDs for all fabric elements (including itself). Principal is the highest priority setting, Default is the next highest, and Never Principal is the lowest priority setting. The setting Never Principal means the switch is incapable of becoming a principal switch. If all switches are set to Principal or Default, the switch with the highest priority and the lowest World Wide Name (WWN) becomes the principal switch. At least one switch in a fabric must be set as Principal or Default. If all switches are set to Never Principal, all interswitch links (ISLs) will segment, causing a failure of connectivity. e. Choose from the Interop Mode drop-down list to set the product operating mode. This option does not display if the Operation mode is S/390. (S/390 mode is not supported with the Edge Switch 2/24.) This setting only affects the mode used to manage the product; it does not affect port operation. Available selections are: - Homogenous Fabric - Choose this option if the product is fabric-attached only to other HP Directors or Switches operating in Homogenous Fabric mode. - Open Fabric 1.0 - Choose this option for managing heterogeneous fabrics and if the product is fabric-attached to HP Directors or Switches and open-fabric compliant switches produced by other original equipment manufacturers (OEMs). 4.
