Standalone vs. | Online | Diagnostics |

|
| |
When | the system | unit attempts to boot in | service mode (from | either | the default or | |
custom | boot | list) | and locates a diagnostics | other | bootable | |
image, | then | the | system unitstandalonestartsdiagnostics | . |
|
|
Standalone diagnostics can be used on system units installed with any supported operating system.
When | the system | unit | attempts to boot in service mode (from | either | the default or | |
custom | boot | list) | and | first locates a bootable image on disk | drive | or network |
connection, | then | the | system unitonline startsdiagnostics . |
|
| |
Online diagnostics can only be used on system units installed with the AIX operating system.
Because | the | type | of diagnostics | started (standalone or online) depends on the |
source | from | which | they are loaded, changing the boot list used during system startup | |
can affect | which | diagnostics are | run. | |
