To be familiar with POR & IPL processPractical experience of POR & IPL of OS/390
throughout the course.

I/O Definitions (IODF)Device definitions are necessary for two reasons
Only defined devices are know to the Channelsubsystem
Only defined devices are know to the OS IODF are made using HCD IODF are stored in IODF datasets IODF datasets are used during IPL to define the
devices to OS, by creating UCB (Unit Control Blocks)
IODF is converted into IOCDS (I/O control datasets)for use during POR.

Loading a copy of the operating system from diskinto the CPU` s central storage SYSRES volume
Single CPU is used
IPL steps1. Bootstrap (Cycl 0, Track 0)
2. IRIM (IPL Resource Initialization Module)
3. NIP (Nucleus Initialization Program)
4. MSI (Mater Scheduler Initialization)5. JES

The Hardware configuration definition is loadedfrom IOCDS into the HSA (Hardware System Area)
HSA is a non-Software addressable piece of CS,
used for a microcode work
LPAR Processing &
I/O configuration data.

Step 21 To complete the IPL process go to the HMC (Hardware
Management Console).
The hardware management console provides a singlepoint of control to manage your central ProcessorComplex
Select the Primary Support Element
Double click the GROUPS in VIEW area.
Click the defined CPCs in WORK area.

Click the IMAGES in WORK area
Select the LPAR which you want to do an IPL.
Double click the LOAD option in Right pane area.
Verify the previous LOAD address & LOADparameter.
Enter the LOAD address & LOAD parameter &click the yes option.
This is the end of IPL Process.

There are Two main steps involved in POR ofa S/390 i.e. POWER ON & POWER OFF, whichis entirely different from ordinary PC.
Steps involved in bringing down or ratherPOR ing the S/390 & later systems(Z/900)

Power off procedure includes three steps
IPL (From step 1 to 20)
IPL of all LPARs
Deactivation of LPARs Finally Power off the ESS & Z900.

Repeat Step 1 to 20 for all LPARs available. Deactivation of LPARs Select the primary Support Element in HMC
Double click the GROUPS in VIEW area.
Click the Defined CPCs in WORK area Click the IMAGES in WORK area.
Select the LAPARs one by one in WORK area & Click theDEACTIVATE option in TASK area.
Double click the GROUPS in VIEW area.
Select Defined CPCs in VIEW area & DEACTIVATE the same.
Press CNTL + DEL
SHUTDOWN the HMC

3 types of Profiles exists. LOAD IMAGE RESET
The Load profile defines parameters for theprocessing unit, load device address, and associatedparameters.
The Reset profile defines the IOCDS, the parametersto power-up and power-on reset, and also identifies
the Load or Image profiles that will be used. The Image profile defines parameters to control the
activation of logical partitions.

After selecting the Profile go to the TASK area clickthe POWER ON RESET option.
Now it will ask for frame select the frame & give yes.
After the POWER ON RESET completion. Double click
the GROUPS in VIEW area. Double click the images on WORK area & activate all
the LPARs one by one.
IPL all the LPARs one by one.

Specify System Parameter Double click the IMAGES in WORK area and select
the any one of the LPAR. Double click the OPERATING SYSTEM MESSAGES in
TASK area. This will ask for system parameters Enter R 00Then JES will come up before which we need to
specify the JES2 parameters( whether Cold/warm
start.)Repeat the above steps for each LPAR.
