Note:
If you rerun the rolling upgrade procedure to remove patches, the prompts you receive during
the setup stage will be different from those issued during the initial rolling upgrade. Those
prompts will look as follows:
Do you want to continue to upgrade the cluster? [yes]: Return
What type of upgrade will be performed?
1) Rolling upgrade using the installupdate command
2) Rolling patch using the dupatch command
3) Both a rolling upgrade and a rolling patch
4) Exit cluster software upgrade
Enter your choice: 2
Displaying the Status of a Rolling Upgrade
The clu_upgrade command provides the following options for displaying the status of a rolling
upgrade. You can run status commands at any time.
• To display the overall status of a rolling upgrade: clu_upgrade -v or clu_upgrade -v
status.
• To determine whether you can run a stage: clu_upgrade check [stage]. If you do not
specify a stage, clu_upgrade tests whether the next stage can be run.
• To determine whether a stage has started or completed: clu_upgrade started stage
or clu_upgrade completed stage.
• To determine whether a member has rolled: clu_upgrade check roll memberid.
• To verify whether tagged files have been created for a layered product: clu_upgrade
tagged check [prod_code [prod_code ...]]. If you do not specify a product code,
clu_upgrade inspects all tagged files in the cluster.
Notes:
During a roll, there might be two versions of the clu_upgrade command in the cluster — an
older version used by members that have not yet rolled, and a newer version (if included in the
update distribution or patch kit). The information that is displayed by the status command
might differ depending on whether the command is run on a member that has rolled. Therefore,
if you run the status command on two members, do not be surprised if the format of the
displayed output is not the same.
If you run clu_upgrade status after running installupdate, clu_upgrade will display
a message indicating that the install stage is complete. However, the install stage is not really
complete until you run the clu_upgrade postinstall command.
Undoing a Stage
The clu_upgrade undo command provides the ability to undo a rolling upgrade that has not
completed the switch stage. You can undo any stage except the switch stage and the clean stage.
You must undo stages in order; for example, if you decide to undo a rolling upgrade after
completing the preinstall stage, you undo the preinstall stage and then undo the setup stage.
