6. Repeat this process for the other cluster member if this is a two-node TruCluster configuration. 6.8.3.4 Obtaining the Worldwide Names of KGPSA Adapters A worldwide name is a unique number assigned to a subsystem by the Institute of Electrical and Electronics Engineers (IEEE) and set by the manufacturer prior to shipping. The worldwide name assigned to a subsystem never changes. We recommend that you obtain and record the worldwide names of Fibre Channel components in case you need to verify their target ID mappings in the operating system. Fibre Channel devices have both a node name and a port name worldwide name, both of which are 64-bit numbers. Most commands that you use with Fibre Channel only show the port name. There are multiple ways to obtain the KGPSA port name worldwide name: • You can obtain the worldwide name from a label on the KGPSA module before you install it. • You can use the show dev command as follows: P00>>> show dev . . . pga0.0.0.1.0 pgb0.0.0.2.0 • PGA0 PGB0 WWN 1000-0000-c920-eda0 WWN 1000-0000-c920-da01 You can use the wwidmgr -show adapter command as follows: P00>>> wwidmgr -show adapter item adapter WWN [ 0] pga0.0.0.4.1 1000-0000-c920-eda0 [ 1] pgb0.0.0.3.0 1000-0000-c920-da01 [9999] All of the above. • Cur. Topo FABRIC FABRIC Next Topo FABRIC FABRIC If the operating system is installed, the worldwide name of a KGPSA adapter is also displayed in the boot messages generated when the emx driver attaches to the adapter when the adapter’s host system boots. Or, you can use the grep utility and obtain the worldwide name from the /var/adm/messages file as follows: # grep wwn /var/adm/messages F/W Rev 2.20X2(1.12): wwn 1000-0000-c920-eda0 F/W Rev 2.20X2(1.12): wwn 1000-0000-c920-eda0 F/W Rev 2.20X2(1.12): wwn 1000-0000-c920-eda0 . . . Record the worldwide name of each KGPSA adapter for later use. Using Fibre Channel Storage 6–41
