You can troubleshoot the upgrade failures using the different options available.
When there is an upgrade failure for a component, the progress bar is displayed in red and you can see the RETRY and DOWNLOAD LOGS buttons.
To retry the upgrade again, click the RETRY button. Alternatively, you can click DOWNLOAD LOGS to download the logfiles.
If the Avamar upgrade fails while upgrading the IDPA appliance software, and if you are retrying the Avamar upgrade even after 24 hours of failure, you must manually upgrade the Avamar server. If the Avamar upgrade fails during the RETRY operation, with a message Validated checkpoint not found, you must manually resolve this issue by creating a checkpoint on the Avamar Server. To create a checkpoint on the Avamar Server, see Upgrade prerequisites. After you create a valid checkpoint, go to the Avamar UI and click the Sync button which is displayed for the failed component.
If the vCenter is rebooted when any component upgrade is in progress, the upgrade process stops. You must wait until the services on the vCenter server are running, and then attempt a retry of the upgrade for that component.
To verify that the vCenter server services are running, log in to the vSphere client console. A successful login indicates that the services on the vCenter server are started.
If the rollback is successful:
If the rollback fails:
If the IDPA rollback fails during the upgrade procedure, perform the following manual steps. Many of these steps are completed by the IDPA upgrade workflow because the IDPA upgrade does not stop operations if an error is encountered.
To delete the BeforeUpgrade VMware vCenter snapshots from all the components, perform the following steps on each of the component where BeforeUpgrade snapshot exists:
/opt/emc/dpa/services/bin/dpa.sh datastore import /data01/datastore-*/
v. Log in to the DPA Application Server using Putty and run the following command:
/opt/emc/dpa/services/bin/dpa.sh service start
vi. Verify that the services are correctly starting by going to https://dpaAppServerIp:9002
service dpworker status
service unicorn status
service elasticsearch status
dpnctl start scheduler
If it is present, record its name and uninstall it by using the –e dataprotection-upgrade-rpm-name command.
service dataprotection_webapp stop
service dataprotection_webapp start
If both the upgrade process and the snapshot recovery fail, collect the log files in the following locations and contact Dell Support:
