  4. What is in a CPU ? • Mainframe, Central Processing Unit (CPU) or Central Processor Complex (CPC) Processors execute instructions Memory stores data Channels connect I/O

  5. IBM Processor • The latest IBM CMOS processor is a model 2064. Also called a Freeway, G7, Generation 7 or zSeries 900 • There are 1 to 16 Processor Units (PU) for customer use • The storage size can be 5 to 64 gigabytes • Can have 0 to 256 chpids installed of many different types

  6. IBM Processor (continued) • The IBM CMOS PU has gained in speed since 1990 • The G1 PU was 15 MIPs vs. the latest G7 PU at 250 MIPs • The present 2064 model 116 has 16 PU’s totaling 2695 MIPs • All CPC have 1 to 8 dedicated PU’s called SAPs for managing the chpids • An internal coupling facility in the CPC may have dedicated PU(s) • There are 20 PU’s on the MCM but only the number purchased are enable • The CPC is controlled from the Hardware Management Console (HMC)

  7. The Hardware Management Console (HMC) • The HMC is a PC that controls and monitors up to 100 different CPCs • The HMC attaches to the CPCs via token ring or ethernet • There are 6 logon classes for the CE, operator and system programmer • Each logon can have unique tasks defined

  8. The Hardware Management Console (continued) • An Activate to a CPC performs a Power on Reset (POR) • If the CPC was powered off, it will be powered up, run power-on • self-tests then POR • An Activate to an Image will IPL that image or LPAR • All activates require an activation profile • Reset profiles define the IOCDS used, operating mode and • storage configuration • Image profiles define the number of dedicated or shared CPs and the • amount of storage used by the LPAR • Load profiles define the IPL address and the loadparm

  9. There are 16 Different chpid Types as Defined by the IOCDS and CPU card Parallel (BY or BL) Gigabit ethernet (OSE) Escon (CNC) Coupling facility sender (CFS) Coupling facility receiver (CFR) Converter (CVC or CBY) Ficon chpid (FC) Integrated CF bus sender (ICS) Ficon bridge (FCV) Integrated CF bus receiver (ICR) CF bus sender (CBS) Serial CTC (CTC) CF bus receiver (CBS) OSA FDDI, ATM, EnTR (OSA) Integrated subsystem DASD (ISD) Fast Ethernet (OSD)

  10. PU Processor Types Processor Unit Processor Unit with crypto Dedicated CF Processor IO Processor

  11. The IOCDS and HCD • An IOCDS is used for the POR when the CPC is activated • The IOCDS defines the channels, control units and IO attached to the CPU • The IOCDS creates the device UCB in the CPC’s Hardware System Area (HSA) during POR ID MSG1='m1185c',MSG2='SYS1.IODF82 - 2002-02-20 16:21', * SYSTEM=(2064,1), * TOK=('MR63',00000001185C2064162122640102051F00000000,000* 00000,'02-02-20','16:21:22','SYS1','IODF82') CHPID PATH=(EC),SHARED, * PARTITION=((ABOC,BDEV,SDEV),(ABOC,BDEV,SDEV)),SWITCH=FB,* TYPE=FCV CHPID PATH=(ED),SHARED, * PARTITION=((ABOC,BDEV,SDEV,TDEV),(ABOC,BDEV,SDEV,TDEV)),* SWITCH=FD,TYPE=FCV CNTLUNIT CUNUMBR=6F00,PATH=(EC,ED),UNITADD=((00,256)), * LINK=(5E,5E),CUADD=7,UNIT=2105 IODEVICE ADDRESS=(6F00,192),CUNUMBR=(6F00),STADET=Y,UNIT=3390B IODEVICE ADDRESS=(6FC0,064),CUNUMBR=(6F00),STADET=Y,UNIT=3390A

  12. IPL is an Acronym for Initial Program Load • The hardware IPL brings in NIP (Nucleus Initialization Program)

  13. Types of IPL Failures • Stuck in Load State • Waitstates • When a problem occurs, the LPAR enters a waitstate • The waitstate could be an enabled or disabled one • Messages – • When a problem occurs, a message is issued to the MVS console • The operator has to take action • No messages or waitstate • The operator will need to investigate where in the IPL phase the failure occurred and take action

  14. Load State IPL failure • The LPAR could be stuck in Load State for several reasons • No valid connection to the selected load device (CC3) • Device error (unit check) on the load device • Channel programming error on an improperly formatted load device. • Anything that causes the load sequence to fail before the IPL Program Status Word takes control, including a bad IPL Program Status Word. • Check the IPL volume for a valid IPL record if the operator isn’t able to run you through the clues in the HMC

  15. Waitstate IPL failures • Enabled waitstates can only be displayed by stopping the LPAR and displaying the PSW. • The PSW is 070E0000 00000000. This waitstate is waiting for operator input during the IPL. This happens when the operator expects to see the ‘Specify System Parameters’ message but their MVS console is broke. The message came up on another MVS console…..somewhere • Disabled waitstates will appear on the HMC console as a blinking blue Hardware Message icon. Need to drop the blue CPC onto the hardware messages to display the waitstate. • Most waitstates are in the 000A0000 xxxxxyyy format. The xxxxx is the reason code and the yyy is the waitstate. • In the following frames, a 03C wait reason 01 is displayed on the HMC

  16. Wait 03C Reason 01 Explanation: The auxiliary storage manager (ASM) found that not enough auxiliary storage space is available for system operation: During IPL: Either the needed number of page data sets was not specified or ASM has detected a problem with a required page data set. Reason Code Explanation: 01 The last local page is full, so there is insufficient local paging space. Look up the MVS waitstates online at http://publibz.boulder.ibm.com/ cgi-bin/bookmgr_OS390/BOOKS/IEA1H721/3.0

  17. PSWs During IPL • 070E0000 00000000 = Normal wait PSW. Waiting for operator response • 000A0000 xxxxxyyy where yyy is the disabled waitstate code and xxxxx is the reason code.  Not all waitstates have reason codes. Some common ones:- 005 - An I/O interruption during IPL indicated a unit check- 007 - No MVS system console- 00E - cannot locate the SYS1.NUCLEUS data set or the system nucleus member - 00F - IPL unit has no IPL text.  Not an IPLable unit.- 064 - Need the RC - NIP detected a software or hardware error -0A2 - Need the RC - XCF encountered a non-recoverable error and stopped the system- 0B1 - Need the RC - problem in the LOADxx parmlib member, the I/O definition file (IODF) data set, or a device.  Check the LOADPARM. •  Here's a full list from IBMMVS command reference

  18. Things to Try When You Cannot IPL • Display all Hardware Messages on the HMC • Check all Optical Network messages on the HMC for channel errors • The IPL pack uses only one path at IPL time. If there is no connectivity, they cannot IPL and will get a CC=3 • The path needs to be configured offline from the LPAR to force the IPL down an alternate path using the HMC • Check the symm for errors and A1,E for access to the LPAR. You will need to see A1,BB to match the GIDN to the LPAR ID and CPU s/n • Trace the device in the symm and look for the x’02’ read IPL CCW

  19. Let’s hear it for Dennis! Stretch Break…

  20. How an I/O Gets Done • The CPU executes a Start Subchannel (SSCH) instruction • SSCH selects the device and points to the subchannel in the I/O subsystem • SSCH points to the Channel Command Words (CCWs) that the device is to perform. • Control blocks associated with SSCH set certain operational controls

  21. The Channel Subsystem • Receives the SSCH information • Checks the info and device for validity • Sends a non-zero completion code to the CPU if they’re invalid. • If they’re valid, selects one of up to 8 paths and signals the device to get on with it

  22. The Device (Symmetrix) • Receives the commands and checks for validity • Command rejects if they’re not correct • Sends info to the back end as needed to perform the function • Transfers data to/from the device and channel

  23. Ending the Operation • The Symmetrix posts a status • Channel end by itself or with • Device end and maybe • Unit check or unit exception • And sometimes a bunch of others • The subchannel receives the status from the Symmetrix as device status

  24. The I/O Interrupt • The subchannel tells a CPU how the operation went • If it was good, then everything’s OK

  25. We’re Trained to THINK Inside the box

  26. But Sometimes We Need to THINK The (Symmetrix) Box

  27. In General, We’re Apt to Look at a Problem as a Symmetrix Issue • Do a health check – no events or issues, then look at external information sources • What’s a health check? James Kim in Asia-Pacific Support has built a presentation to show that
