IBM SY44-5902-05 manual Debug the resource

The Create containing hardware resource function key is available only on the packaging hardware resources displays. To access this function from the logical displays, you must select the Associated packaging resource(s) option (see “Display associated resources” on page 67).

Debug the resource

From packaging displays:

The I/O debug option is available only on the logical hardware resources displays. To access I/O debug from the packaging displays, you must select the Associated logical resource(s) option (see “Display associated resources” on page 67).

From logical displays:

The I/O debug option is available only on the logical hardware resources displays. This option assists in debugging selected resources.

Note: Attention! Misuse of this option might cause a system software failure.

The I/O Debug display shows the following options as appropriate for the resource selected:

vRead/write I/O processor data

vDump I/O processor data (see “Performing an IOP dump using hardware service manager (All Models)” on page 279)

vReset I/O processor - Some debug functions require that the I/O processor be in a disabled state. Select this option to disable the I/O processor. To enable the I/O processor for normal operation, you must select the IPL I/O processor option on the Select I/O Debug Function display or IPL the server again.

vIPL I/O processor - Select this option to IPL the I/O processor. It allows you to recover from an intermittent problem, refresh the I/O processor system information, or enable the I/O processor for normal operation after selecting the reset I/O processor option. Selecting this option performs the same function as the OS/400 vary command with the reset option (see “How to reset an I/O processor card while the system is up and running” on page 295).

vEnable I/O processor trace — Select this option to enable IOP trace.

vDisable I/O processor trace — Select this option to disable IOP trace.

vEnable I/O processor reset — Select this function key to enable IOP reset (one IOP or all IOPs on a bus). Attention! This function is for iSeries development use only and is not for use in customer installations. Using this option can disrupt system operations and lead to catastrophic system failures.

vDisable I/O processor reset — Select this function key to disable IOP reset. Attention! This function is for iSeries development use only and is not for use in customer installations. Using this option can disrupt system operations and lead to catastrophic system failures.

vEnable I/O processor IPL — Select this function key to enable IOP IPL (one IOP or all IOPs on a bus). Attention! This function is for iSeries development use only and is not for use in customer installations. Using this option can disrupt system operations and lead to catastrophic system failures.

vDisable I/O processor IPL — Select this function key to disable IOP IPL. Attention! This function is for iSeries development use only and is not for use in customer installations. Using this option can disrupt system operations and lead to catastrophic system failures.

vEnable bus trace — Select this option to enable a bus trace.
