Creating an IOCDS source file for a new CPC
All logical partitions, channel paths, control units, and I/O devices must be defined in the IOCDS source file to generate an IOCDS, which can then be used to perform power-on reset of the CPC.
Create an IOCDS source file as part of the installation procedure for a new CPC.
After completing the input, save the edited file and exit the editor.
Use another CPC running an operating system version of IOCP (z/OS®, z/VM®, or z/VSE®) to verify the card-image input statements for this IOCDS source file. If you do not have access to an operating system version of IOCP capable of verifying an IOCDS source file, ask your service representative to verify the IOCDS source for you.
If you are upgrading to a CPC whose SYSTEM= value supports execution parameter CHECKCPC=NO, write the IOCDS for the new CPC on your current CPC using CHECKCPC=NO. See Machine rules to determine which CPCs can write an IOCDS in preparation for an upgrade and which CPCs can have an IOCDS written to them by ICP IOCP. Inform the service representative which IOCDS to use after the upgrade.
If you are not upgrading or cannot write an IOCDS in preparation for the upgrade, use a utility available to your personal computer and operating system to download the IOCDS source file to USB flash memory drive. Source from a flash memory drive can be in VFAT or DOS file formats or have been compressed. The IOCDS source file you create must be available to the new CPC installer at the time the new CPC is installed. Instead of a USB flash memory drive, you can import an uncompressed IOCP source file to the SE from an FTP location.
