What is a design consideration when adding an HPUX-based server to a current Brocade fibre solution?
A. Initiator zoning is needed
B. The domain ID 8 must not be used on any switch
C. The B-series Switch Adaptive Networking license is needed
D. The HPUX server must be within three hops of the SAN Storage
Correct Answer: B
Explanation/Reference:
Explanation/Reference:
For zoning by HBA, each zone has only one HBA (initiator); each of the target devices is added to the zone.
Typically, a zone is created for the HBA and the disk storage ports are added. If the HBA also accesses tape devices, HP recommends that a second zone be created for the HBA and associated tape devices. For zoning requirements with different HBA models on the same server Setting the Domain ID:
Each switch in the fabric must have a unique domain ID. The domain ID can be manually set through the configure command or can be automatically set. The default domain ID for the Brocade DCX 8510-8 is 1. Use the fabricShow command to view the already assigned domain IDs.

Domain id 8 conflict with hpux:
DON’T* use domain ID 8 with HP-UX!
In the way like HW-Pathes are build and drivers work, the "8" indicates FC_AL mode, even if your SAN is fabric, because the "8" stands for "storage" in FC_AL. Switch to another ID!. If you are going to swap your switches, make sure to use the same domain ID and port number to connect the storage devices, because HP-UX is using both to build the hardware path. Specifically, don’t use domain id 8 ("Do not configure switches with a domain of 8.
This configuration is unsupported and will not work. HP systems reserve domain 8 for Private Loop devices.") and use vgexport/ vgimport to associate LUN with the new device files you will have after the change.
