Display/Alter Sector
This selection allows the user to display and alter information on a disk sector.
Note: Use caution when you use this service aid because inappropriate modification
to some disk sectors can result in total loss of all data on the disk.
Sectors are addressed by their decimal sector number. Data is displayed both in
hex and in ASCII. To prevent corrupted data from being accessed, the service aid
does not display information that cannot be read correctly.
Display Configuration and Resource List
If a device is not included in the Test List or if you think a Diagnostic Package for a
device is not loaded, check by using the Display Configuration and Resource List
task. If the device you want to test has a plus (+) sign or a minus (-) sign preceding
its name, the Diagnostic Package is loaded. If the device has an asterisk (*)
preceding its name, the Diagnostic Package for the device is not loaded or is not
available.
This service aid displays the item header only for all installed resources, no vital
product data (VPD) is displayed. Use this service aid when there is no need to see
the VPD.
