IBM pSeries690 Step 3 , Step 4 , Step 5

Step 3 Determine if the partition is accepting commands.
Is the operating system accepting commands?
NO If a partition is not accepting commands (or if the partition has an
operating system other than AIX installed), run standalone
diagnostics.
YES Go to “Step 4”.
Step 4 Diagnostic tests can be run on many resources while the operating system is running.
However, you can obtain more extensive problem isolation by running online
diagnostics in service mode.
Do you want to run the online diagnostics in service mode?
NO Go to “Step 5”.
YES Go to “Step 6” on page 147.
Step 5 This step starts the online diagnostics in concurrent mode.
Note: The AIX operating system must be installed on the partition on which you want
to run online diagnostics.
1. Log in as root user or use CE Login.
2. Enter the diag command.
3. Wait until the diagnostic operating instructions display, or wait for three minutes.
Are the diagnostic operating instructions displayed without any obvious console
display problems?
NO If the diagnostics operating instructions are not displayed on the
partition, reboot that partition.
Note: Do not turn off the system unit if the system is running one or
more logical partitions.
Go to “Step 6” on page 147.
