a. Select the Maintenance mode option from the displayed menu.
b. After the node boots to Maintenance mode, halt the node:
halt
After you issue the command, you should wait until the system stops at the LOADER prompt.
During the boot process, you can safely respond
y
to prompts:
▪
A prompt warning that when entering Maintenance mode in an HA configuration, you must ensure
that the healthy node remains down.
2. At the LOADER prompt, access the special drivers specifically designed for system-level diagnostics to
function properly:
boot_diags
During the boot process, you can safely respond
y
to the prompts until the Maintenance mode prompt (*>)
appears.
3. Run diagnostics on the system memory:
sldiag device run -dev mem
4. Verify that no hardware problems resulted from the replacement of the DIMMs:
sldiag device status
-dev mem -long -state failed
System-level diagnostics returns you to the prompt if there are no test failures, or lists the full status of
failures resulting from testing the component.
5. Proceed based on the result of the preceding step:
If the system-level diagnostics
tests…
Then…
Were completed without any
failures
a. Clear the status logs:
sldiag device clearstatus
b. Verify that the log was cleared:
sldiag device status
The following default response is displayed:
SLDIAG: No log messages are present.
c. Exit Maintenance mode:
halt
The node displays the LOADER prompt.
d. Boot the node from the LOADER prompt:
bye
e. Return the node to normal operation:
If your node is in…
Then…
An HA pair
Perform a give back:
storage failover giveback -ofnode
replacement_node_name
If you disabled automatic giveback, re-enable it with
the storage failover modify command.
