IBM SY44-5902-05 manual Control Panel Functions

Function 63–System Status SRC Trace: The system status SRC trace is a copy of the last 25 status SRCs (those that are usually 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.

See “Low-level debug and data collecting procedures” on page 131 for more information.

Function 64–Diagnostic Status SRC Trace: The diagnostic status SRC trace is a copy of the last 25 status SRCs (those that are usually associated with the service processor function of problem analysis and main store 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.

See “Low-level debug and data collecting procedures” on page 131 for more information.

Function 65–Deactivate Remote Service: Function 65 is available only when you have previously selected Manual mode and extended panel functions 25 and 26.

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

Function 66–Activate Remote Service: Function 66 is available only when you have previously selected Manual mode and extended panel functions 25 and 26.

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

Function 67–Disk Unit IOP Reset/Reload: Function 67 is not available for all system types.

This function is used 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–MFIOP Control Storage Dump: This function dumps the contents of the control storage from the MFIOP to segment identifier (SID) 0000000087 000000 (SID 87) on the load-source disk.
