Performing an IOP dump using hardware service manager (All Models)

You can perform I/O processor storage dumps by using the I/O debug option on the Logical Hardware Resources display (under Hardware Service Manager). Use this utility under the direction of your next level of support. For more information on the Hardware Service Manager function, see Chapter 2, “Hardware Service Manager” on page 45.

The Logical Hardware Resources display (under Hardware Service Manager) lists the logical resources that are attached to the system bus. Select the I/O debug option to access the IOP dump function. The IOP dump function allows you to collect, display, print, and save data from the I/O processor. The dump is written to a temporary disk storage area. When you exit the Hardware Service Manager function, the dump is lost.
