Low-level debug panel functions 57 through 70

 

You can enable these functions by selecting Manual mode and selecting functions 25 and 26.

Here is a list of all the low-level debug panel functions and a description of each:

Function 57 - Display Service Processor Diagnostic Data Area Addresses

These addresses can be used to display debug data in function 62.

Function 58 - Setting First Character of the Base Address for the Function 62 Display

Function 59 - Setting Second Character of the Base Address for the Function 62 Display

Function 60 - Setting Third Character of Base Address for the Function 62 Display

Function 61 - Setting Fourth Character of Base Address for the Function 62 Display

Function 62 - Display Service Processor Storage

This function displays service processor storage starting at the address that has been set with functions 58 through 61.

Function 63 - System Status SRC Trace

The system status SRC trace is a copy of the last 25 status SRCs (those that are typically associated with the IPL sequence or the turn-off sequence). Enter a subfunction between hexadecimal 00 and 18 to look at the status SRCs in sequential order. The most recent SRC (the last status SRC) is displayed at subfunction hexadecimal 18.

Function 64 - Diagnostic Status SRC Trace

The diagnostic status SRC trace is a copy of the last 25 status SRCs (those that are typically associated with the service processor function of problem analysis and main storage dump). Enter a subfunction between hexadecimal 00 and 18 to look at the status SRCs in sequence. You can see the most recent SRC (the last status SRC) at subfunction hexadecimal 18 and the extended SRC words for this SRC at subfunctions 19 through 1A.

Function 65 - Deactivate Remote Service

Use this function to deactivate a remote service session or Operations Console. This function releases the communications port that was in use for a remote service session or Operations Console.

Function 66 - Activate Remote Service

Use this function to activate a remote service session or Operations Console. This function activates the communications port that is used by a remote service session or Operations Console.

Function 67 - Disk Unit IOP Reset/Reload

Function 67 is not available for all system types. Use this function to initiate an IOP dump and a disk unit IOP reset/reload. The function is enabled only when specific SRCs are displayed on the control panel and the associated IOP supports a reset/reload function.

Function 68 - Turn off Disk Unit IOP/IOA Power Domain

Function 68 is enabled only by specific disk-unit system reference codes (SRCs) such as disk-unit attention SRCs.

Function 69 - Turn on Disk Unit IOP/IOA Power Domain

Function 69 is enabled when the power domain is turned off.

Function 70 - Dump Service Processor Control Storage

This function saves the contents of the service processor control storage into nonvolatile storage for potential use from an error log.
