Final Array Configuration Step 18. Gather Host WWNs The host WWN is used for defining the port behavior for a host, and for managing LUN security. Either the node or port WWN can be used. Before building either the host port behavior table or the LUN security table, you must gather the WWNs associated with each host that will be accessing the array. This step is only required in heterogeneous host environments, or if Secure Manager will be used to implement LUN security. There are two options for identifying the host WWN. Using the armtopology command The armtopology command available in the CLUI displays information, including the WWN, for any host running CommandView SDM. If CommandView SDM is loaded on all hosts, you can identify all host WWNs using armtopology. The armtopology command has the following structure: armtopology ... where is the DNS name or the IP address of each host Example output: Host Host Node WWN Host Port WWN Product SerialNumber C RG LUN Device path host1 50060b0000017ee0 50060b0000017ee1 A6188A 00USP1001064 1 1 1 \\.\PHYSICALDRIVE1 host2 50060b00000158f8 50060b00000158f9 A6188A 00USP1001064 2 2 0 /dev/rdsk/c0t0d0 host3 50060b000006a964 50060b000006a965 A6189A 00USP1001234 1 1 0 /dev/rdsk/c1t0d0 Using Host and Adapter Utilities For hosts not running CommandView SDM, another method must be used to determine the host WWN. Each host should have specific utilities - operating system or host adapter - which can be used to identify the host WWNs. ■ For HP-UX, run the fcutil command. For example, for a Fibre Channel array named "fcms1", enter: /opt/fcms/bin/fcmsutil/dev/fcms1 44 Virtual Array Installation Guide
