This section includes the prerequisites that you must complete before you begin the upgrade procedure.
- Ensure that the IDPA firmware is updated.
Note: All the existing Avamar packages and the snapshots are deleted before the upgrade.
- Ensure that the IP address 192.168.100.113 is not in use during the upgrade.
- Review the Integrated Data Protection Appliance Release Notes for information specific to the current release.
- If you have NDMP Accelerator nodes added to IDPA, you must manually upgrade the NDMP accelerator nodes. To upgrade NDMP accelerator nodes, see the section “Upgrading the accelerator software” in the Dell EMC Avamar NDMP Accelerator for Dell EMC NAS Systems User Guide.
- Begin an upgrade only during a software-upgrade maintenance window. Ensure that no other maintenance or backup activity is occurring on Avamar or Avamar Virtual Edition during the upgrade process. Avamar jobs should not be running, and Avamar Server status should be idle. You can check the server status by running the following command on the Avamar server:
admin@vdppunvm140:~/>: status.dpn
- Record the search settings before starting the upgrade procedure, because as part of the upgrade, search is also upgraded. The search upgrade consists of deleting the old search VM and adding the new search VM. This action deletes all the search settings such as the custom user permissions and email notifications after the upgrade. Similarly, the LDAP settings are stored on ACM, and ACM restores the previous LDAP settings on the new search VM after the upgrade.
- Ensure that all the ESXi passwords are synchronized with ACM. If you have changed the ESXi passwords, see ESXi settings under the section “Change passwords and synchronize components” the IDPA Product Guide to synchronize them.
- Ensure that the ACM dashboard is not displaying any Password out of sync messages for any of the components.
- Ensure that the vCenter passwords are synchronized with ACM. If you have changed the vCenter password, see the section “Change passwords and synchronize components” in the IDPA Product Guide.
- Ensure that the ESXi server is up and running by verifying it status on the vCenter UI.
- Ensure that Avamar and DD Series storage consumption is less than 85 percent. See the sections “Monitoring the system with the Avamar Administrator Dashboard” and “Monitoring Data Domain system capacity” in the Dell EMC Avamar Data Domain System Integration Guide for more information.
- Disable all the backup policies through the Avamar UI. See the section “Enabling and disabling a backup policy” in the Dell EMC Avamar Administration Guide.
- Restart MCS on Avamar before starting the upgrade process to ensure Avamar is quiesced, so that the upgrade does not fail due to Avamar being busy.
To restart MCS on Avamar, log in to the Avamar Utility Node with SSH (ssh login credential is admin and the password is the common appliance password that you would have provided) by using the Avamar IP address, and run the command to stop it:
dpnctl stop mcs
- Next, run the command to restart the Avamar Server:
dpnctl start mcs
- Ensure that you check the health of the vCenter before the upgrade procedure. To check the health of the vCenter, log in to the vCenter Web interface. If there are any critical alerts requiring user action, you must first fix those critical alerts before starting the IDPA upgrade procedure.
