  • Troubleshooting FICON
    Send documentation comments to [email protected] CHAPTER 16 Troubleshooting FICON Fibre Connection (FICON) interface capabilities enhance the Cisco MDS 9000 Family by supporting both open systems and mainframe storage network environments. Inclusion of Control Unit Port (CUP) support further enhances the MDS offering by allowing in-band management of the switch from FICON processors. This chapter includes the following sections: • FICON Overview, page 16-1 • FICON Configuration Requirements, page 16-6 • Initial Troubleshooting Checklist, page 16-7 • FICON Issues, page 16-9 FICON Overview The Cisco MDS 9000 Family supports the Fibre Channel, FICON, iSCSI, and FCIP capabilities within a single, high-availability platform. Fibre Channel and FICON are different FC4 protocols and their traffic are independent of each other. If required, devices using these protocols can be isolated using VSANs. The Cisco SAN-OS FICON feature supports high-availability, scalability, and SAN extension technologies including VSANs, IVR, FCIP, and PortChannels. Tip When you create a mixed environment, place all FICON devices in one VSAN (other than the default VSAN) and segregate the FCP switch ports in a separate VSAN (other than the default VSAN). This isolation ensures proper communication for all connected devices. You can implement FICON on the following switches: • Any switch in the Cisco MDS 9500 Series. • Any switch in the Cisco MDS 9200 Series (including the Cisco MDS 9222i Multiservice Modular Switch). • Cisco MDS 9134 Multilayer Fabric Switch. • MDS 9000 Family 18/4-Port Multiservice Module. Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05 16-1 Chapter 16 Troubleshooting FICON FICON Overview Send documentation comments to [email protected] Note The FICON feature is not supported on Cisco MDS 9120, 9124 or 9140 switches, the 32-port Fibre Channel switching module, Cisco Fabric Switch for HP c-Class BladeSystem or Cisco Fabric Switch for IBM BladeCenter.

Time to complete: 10 - 15 minutes ¾The central processor complex ¾The multichip module ¾Memory cards ¾Input/output connections ¾The mainframe’s processing capacity © Copyright IBM Corp. 2006. All rights reserved. The central processor complex z/OS Basic Skills: The mainframe’s processors Mainframe’s processors > The central processor complex Mainframes have one or two metal frames that contain specialized cages, as well as other physical elements. This diagram shows the interior front view of an IBM System z9 Enterprise Class (z9 EC) model that has two frames. The z9 EC is slightly larger than a household refrigerator. The central processor complex, or CPC, resides in its own cage inside the mainframe, and consists of one to four book packages. Just like its personal-computer counterpart, the motherboard or system board, each book package consists of processors, memory, timers, and I/O connections. These collections of hardware parts are called “book packages” because you can slide them in or out of the CPC cage almost as easily as you can slide a book on or off a bookshelf. © Copyright IBM Corp. 2006. All rights reserved. z/OS Basic Skills: The mainframe’s processors Mainframe’s processors > The book package In the System z9, as well as earlier IBM mainframe models, the book package consists of three distinct areas, one each for: • The z9 EC's processors, which are inside one multichip module • Memory cards • Connections to input/output devices All of the book packages plug into a backplane in the z9 EC's frame.
