Resetting a disk unit IOP with logical partitions

Use this function to initiate an I/O processor (IOP) dump and an IOP reset or an IOP reload.

Only use this procedure when directed by your service representative

This function becomes enabled when certain disk unit SRCs appear and the associated IOP supports a reset or reload function.

Attention: Incorrect use of this function can cause loss of data. It can also cause failures that may be incorrectly diagnosed as expensive hardware failures.

To reset a disk unit IOP, you should be working with the remote control panel. Function 67 resets/reloads the disk unit IOP.
