Concurrent Mode
Use | concurrent | mode | to | run Online Diagnostics on some | of the | system resources | |
while the system is running normal activity. |
|
| |||||
Because the | system | is | running in normal operation, the | following | resources cannot | ||
be | tested | in | concurrent | mode: |
|
| |
Ÿ SCSI adapters connected to paging devices
Ÿ Disk drive used for paging
Ÿ Some display adapters and graphics related devices
Ÿ Memory (tested during POST)
ŸProcessor (tested during POST)
Three levels of testing exist in concurrent mode:
ŸThe
programs running in the normal operation. This testing is mostly limited to normal 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
operation. | This | level of | testing | on a | disk drive | might require the use | of the | |||
varyoff | command. | The | diagnostics display | menus | to | allow you to vary off | the | |||
needed | resource. |
