Upgrade the appliance software

1. Download the upgrade package file from Dell Support and use the md5sum validation process to verify its integrity. The name of the file is in the format IDPA_Upgrade_< version >.tar.gz.

1. Copy the file to /data01/upgrade on the ACM.

Note: Ensure that only the upgrade file exists in this folder and no other post or prepatch packages exist.

1. Ensure that you have the executable permission for the upgrade package that you copied to the /data01/upgrade directory.

If you do not have the executable permission, enter chmod 644 Idpa_Upgrade_< version >.tar.gz command to obtain the permission.

1. Log in to the ACM and click the Upgrade tab. The latest upgrade package file is automatically detected and is displayed in Upgrade Binary Location.
2. Click Extract . After the tar.gz file is extracted, a new window opens and the validations are performed.

Note: The validation process takes approximately 15 minutes, and the ACM can time out while waiting. To resume the session, you must log in again.

The system validates the following:

• VLAN status
• Connection to all components
• License status.
• Avamar services are running
• No backup jobs are running on Avamar
• DD Series capacity used is less than 85%
• Avamar Checkpoint validates if the vCSA root account password is expired
• vCSA administrator and root user account passwords are synchronized

Note the following ESXi upgrade prerequisites:

• Valid connection points to the required ESXi servers
• ESXi Server can enter and exit maintenance mode successfully before the upgrade
• VCSA version is higher than the ESXi version
• If there is a major upgrade to VCSA, the private IP address of the VCSA, 192.168.100.108 , should not be in use in the customer environment because it is temporarily used by IDPA.

Note: The private IP address of the VCSA, 192.168.100.108 , is only required temporarily during the upgrade process.

A table displays the current version, new version, and type (for example, major, patch) of each component for which an upgrade is available.

If the validation is not successful, check the errors that are displayed when you hover on the exclamation mark. Resolve all the errors and click Revalidate . If you want to cancel the upgrade and return to the ACM dashboard, click Cancel .

1. Click Upgrade , type the ACM password, and click Authenticate.
2. To start the upgrade, click Yes . To cancel the upgrade, click No .

The upgrade process starts. The ACM also undergoes an upgrade which results in users getting logged out of ACM.

Note: The upgrade process can take five to six hours, during which all jobs on the IDPA must be quiesced. The system is not accessible during parts of the upgrade.

Note: If the upgrade process is still running, do not shut down or reboot the ACM or restart the dataprotection_webapp service .

If you have shut down or rebooted the ACM, or if you have restarted the dataprotection_webapp service while the upgrade process is still running, and if you are unable to see the progress of the upgrade after the ACM is rebooted, contact Dell Support.

1. Log in again to the ACM. The Upgrade Progress displays the following:

• The ACM upgrade progress bar with the progress percentage and the description of the upgrade step that is in progress.
• The individual component upgrade progress bar with the progress percentage and the description of the upgrade step that is in progress.

1. After all components are upgraded successfully and the overall IDPA upgrade progress bar shows 100%, click Finish .
2. Click OK on the Upgrade Finish window to reboot the IDPA system.

Note: After the upgrade is complete, there can be a scenario where Avamar is in maintenance mode and the jobs cannot be started then. After Avamar comes out of the maintenance mode, the jobs are started as per the next schedule.

Note: After the upgrade is complete, acknowledge the notification Event ConnectEMC notification failed on the Avamar Administrator user interface. This notification is generated during upgrade when the Avamar service is disconnected.

Note: After the upgrade is complete, there is a warning on vCenter about a potential vulnerability issue that is described in CVE-2018-3646. See https://kb.vmware.com/s/article/57374 and https://kb.vmware.com/s/article/55806 for more information. IDPA uses the ESXi version which has the fix for this vulnerability, however this fix is not enabled by default as it has severe performance impact. See the “Security updates and patching” section on the IDPA Security Configuration Guide for more information.

The following components are updated:

• Backup Server (Avamar)
• IDPA System Manager (Data Protection Central)
• Reporting and Analytics (Data Protection Advisor)
• Search
• Protection Storage (Data Domain)
• ACM
• VCSA (vCenter Server Appliance)
• Compute nodes (ESXi)

The dashboard with all the products and their upgraded versions is displayed along with the newly configured ACM.

If the upgrade for any component fails, then the upgrade process is stopped until you troubleshoot and resolve the failure. However, if there are any noncritical warnings, the upgrade process continues. These warnings must be resolved once the upgrade process is completed to ensure a trouble-free operation of IDPA.
