Input/Output configuration window
The Input/Output Configuration window of the Support Element is the starting point for all of the stand-alone IOCP functions.
You can select a particular configuration to work with from this window or see the status of each configuration. This window, found in the Stand-Alone IOCP User's Guide for your CPC, shows that there are four IOCDSs identified as A0-A3, and these have names that you supply.
The fifth IOCDS, D0, is a diagnostic IOCDS. You cannot alter D0. It is intended for service personnel to use, with the following possible exception. If you cannot perform a power-on reset and activate a logical partition in ESA/390 mode using any of the A0-A3 IOCDSs, you can use D0 to perform the power-on reset. I/O cannot be accessed after a D0 power-on reset.
The Stand-Alone IOCP User's Guide explains the Input/Output Configuration window of the Support Element and the Options and View actions (see Related information). This window provides access to all of the information about the IOCDSs currently available on the CPC. You can use the functions under Options to change that information.
- Data Set
- Is a 2-character identifier for the IOCDS. There are five IOCDSs (A0, A1, A2, A3, and D0).
- Name
- Is an 8-character name that identifies the IOCDS. The name comes
from the first eight characters that you have entered in the
MSG1=
keyword in the ID statement. The displayed name is saved from the IOCDS when it is written to the Support Element. - Write Protected
- Write-protection prevents batch IOCP or stand-alone IOCP from
overwriting the IOCDS.
- NO
- Indicates that the IOCDS is not write-protected.
- YES
- Indicates that the IOCDS is write-protected.
- Date
- Is the month, day, and year when the IOCDS was built.
- Time
- Is the hour and minute when the IOCDS was built. (Displayed in 24-hour format).
- Data Set Status
- Can be one of the following:
- Valid
- Indicates the IOCDS is usable for power-on-reset purposes. Its content matches the source only if the source status is Verified or Warnings.
- Invalid
- Specifies the IOCDS is not usable for power-on reset purposes. Either IOCP is currently writing to the IOCDS or the IOCDS was written in preparation for a CPC upgrade and is unusable until the CPC is upgraded to the type of CPC the IOCDS supports.
- Active
- Specifies this IOCDS was used during the most recent power-on reset or was selected by a dynamic activation from the SCP. Only one IOCDS can be active at a given time. The active IOCDS is made write-protected by the Support Element during POR with the IOCDS or after a dynamic activation by the SCP.
- Source Status
- Can be one of the following:
- Verified
- Indicates that the stand-alone IOCP Build was processed with the source for the selected IOCDS and was successful with no warnings or errors.
- Warnings
- Indicates that the stand-alone IOCP Build was processed with the source for the selected IOCDS and was successful with one or more warnings or cautions.
- Errors
- Indicates that the stand-alone IOCP Build was processed with the
source for the selected IOCDS and was not successful. There was a
terminal error. Note: No IOCDS is written and the IOCDS remains as it was before the build.
- Modified
- Indicates that the source for the selected IOCDS has been changed by editing the file. This value also indicates that the source might not match the current IOCDS.
- Imported
- Indicates that an import overlaid the source file.
- Empty
- Indicates that the source for the selected IOCDS has been deleted or was erased when a batch
IOCP program wrote the IOCDS.
Batch IOCP programs are the versions of IOCP that run in a host operating system. Note that HCD uses batch IOCP when writing an IOCDS. When an IOCDS is written by IOCP or HCD from an operating system, the IOCP source file on the SE is empty since the operating system or HCD has the IOCP source file used to write the IOCDS. Source Status of Empty is expected when IOCP or HCD is used to write the IOCDS.
- Version
- Number that identifies which version of IOCP was used to create the IOCDS.
