Concurrent Mode
Concurrent mode provides a way to run Online Diagnostics on some of the system resources while the system is running normal system activity.
Because the system is running in normal operation, some of the resources cannot be tested in concurrent mode. The following resources cannot be tested in concurrent mode:
Ÿ SCSI adapters connected to paging devices
Ÿ The disk drive used for paging
ŸSome display adapters
ŸMemory
ŸProcessor.
There are three levels of testing in concurrent mode:
ŸThe
commands that test for the presence of a device or adapter.
ŸThe
resource is being used in | normal operation. For example, this | test | could test one |
port of a multiport device | while the other ports are being | used | in normal |
operation. |
|
|
|
ŸThe
Error log analysis is done in concurrent mode when you select the Problem
Determination | option | on | the | DIAGNOSTIC MODE SELECTION | menu. | ||
To run the Online Diagnostics in concurrent mode | you must be logged onto the AIX | ||||||
operating | system | and | have | proper authority to | issue the commands (if needed, get | ||
help). |
