Reset Drive

Aborts the operation and causes the drive code to restart. If dump data is in the drive, it is not lost.

Note: Current operation (for example Locate) will be completed before Reset Drive runs. This may cause a delay before Reset Drive is run.

Force Error Dump

Aborts the operation, causes a recovery of the functional code, and forces a microcode dump. After getting the dump, select Reset Drive. This selection is normally used because of specific requests from support personnel.

Choosing Reset Drive or Force Error Dump causes the menu that is shown in Figure 11 on page 35 to appear.
