Chapter | 5. Using | the Online and | Standalone Diagnostics |
| |||
The | diagnostics | consist | of Online Diagnostics and Standalone | diagnostics. | |||
Online | Diagnostics, | when | they | are installed, reside with | AIX in the file system. | ||
can | be booted: |
|
|
|
|
| |
Ÿ in |
| single user | mode | (referseredvice tomode) as |
|
Ÿ run in maintenance mode (referredmaintenanceto asmode)
Ÿrun concurrently (referredconcurrentto asmode) with other applications.
If | the system | is not booted, | the Online Diagnostics | have | access | to | the | AIX e | |
and the AIX configuration data. |
|
|
|
|
|
| |||
Standalone Diagnostics are packaged on removable media | and | must | be | booted |
| ||||
before they can be run. If | booted, they have no | access | to | the | AIX | error | |||
AIX | configuration | data. |

Online | and | Standalone | Diagnostics | Operating Considerations |
|
|
|
|
|
|
|
|
|
|
|
| |||
Note: | When possible, | run Online Diagnostics in service | mode. | Online | Diagnostics |
| |||||||||||||
perform additional functions, compared to Standalone Diagnostics. Running Online |
|
| |||||||||||||||||
Diagnostics in service mode ensures | that | the | error | state | of | the | system | is | capt | ||||||||||
NVRAM | for | your | use | in fixing the problem. The | AIX error | log | and | certain | SMIT |
| |||||||||
functions | are | only | available when | diagnostics are run |
| from | the | disk | drive. |
|
| ||||||||
Consider | the following items before using the diagnostics: |
|
|
|
|
|
|
|
| ||||||||||
Ÿ When | diagnostics | are | installed, | the device | support | for | some | devices | might | not | |||||||||
get installed. If this is the |
| case, | that | device | does | not | appear | in | the | di | |||||||||
test | list when running | diagnostics. |
|
|
|
|
|
|
|
|
|
|
ŸSupport for some TTY terminals is optionally installed. If you attach a TTY
terminal to | a system | to run | diagnostics, | it | might not work correctly because t |
AIX support | for the | terminal | might not | be | installed. |
Selecting a Console Display
When you run Standalone Diagnostics (and under some conditions, Online Diagnostics), you must select the console display. The diagnostics can display instructions on any graphical display and the terminal attached to the S1 serial
