You can enable these functions by selecting manual mode and selecting Functions 25 and 26.
The following 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 Address for Function 62 Display.
Function 61 - Setting Fourth Character of Address for 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 power-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) appears 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 - Power 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 - Power on Disk Unit IOP/IOA Power Domain. Function 69 is enabled when the power domain is powered 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.
