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:
v Read/write I/O processor data
v Dump I/O processor data (see “Performing an IOP dump using hardware
service manager (All Models)” on page 279)
v Reset 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.
