Locating the WWPN for IBM Power Systems hosts running IBM i

Edit online

To attach your DS8000® to an IBM® i host that is running the IBM i operating system, you must locate the worldwide port name (WWPN) for the host.

Before you begin

You can find the 16-digit WWPN for an IBM i host using either of the following methods:
  • Append the number 1000 to the beginning of the 12-digit IEEE address that is found on the tailstock label or the back side of the Fibre Channel input/output adapter (IOA).
  • Display the details for the Fibre Channel Storage IOA through the Logical Hardware Resource information in the Hardware Service Manager in SST/DST.

If your IBM i host is attached to the DS8000 through a virtual Fibre Channel (vFC) N_port ID virtualization (NPIV) connection, you can find the WWPN in the Virtual Fibre Channel Properties in the Hardware Management Console.

Procedure

To locate the WWPN in System Service Tools (SST), complete the following steps:

  1. On the IBM i Main Menu panel, type strsst.
  2. On the Start Service Tools (STRSST) Sign On panel, type your service tools user ID and password.
  3. On the System Service Tools (SST) panel, type 1 to select Start a service tool.
  4. On the Start a Service Tool panel, type 7 to select Hardware service manager.
  5. On the Hardware Service Manager panel, type 1 to select Packaging hardware resources (systems, frames, cards).
  6. On the Packaging Hardware Resources panel, type 9 to select the System Expansion unit.
  7. On the Packaging Hardware Resources panel, type 8 to select Storage IOA.
  8. On the Logical Resources Associated with a Packaging Resource panel, type 5 to select Storage IOA.
  9. On the Auxiliary Storage Hardware Resource Detail panel, locate the field name for the worldwide port name. The number in the right column is the WWPN.
    Note: If you exchanged a Fibre Channel IOA in the IBM i operating system partition, you must update the WWPN of the new IOA in the storage subsystem and any SAN fabric configurations that you need.
