Perform rolling upgrade on a single host or multiple hosts

04/26/2022 Contributors

You can perform rolling upgrade on a single or multiple SnapManager server hosts by using the command-line interface (CLI). The upgraded SnapManager server host is then managed only with the later version of SnapManager.

What you'll need

You must ensure that all the prerequisites for performing rolling upgrade are completed.

Steps

To perform a rolling upgrade on a single host, enter the following command:

smsap repository rollingupgrade-repository-dbname repo_service_name -host repo_host -login-username repo_username -port repo_port -upgradehost host_with_target_database -force [-quiet | -verbose]

The following command performs the rolling upgrade of all target databases mounted on hostA and a repository database named repoA located on repo_host:
```
smsap repository rollingupgrade
    -repository
      -dbname repoA
      -host repo_host
      -login
       -username repouser
       -port 1521
     -upgradehost hostA
```

To perform a rolling upgrade on multiple hosts, enter the following command: smsaprepository rollingupgrade-repository-dbnamerepo_service_name-hostrepo_host-login-usernamerepo_username-portrepo_port-upgradehosthost_with_target_database1,host_with_target_database2-force [-quiet | -verbose]

For multiple hosts, enter the host names separated by a comma and ensure that you do not include any space between the comma and the next host name.If you are using a Real Application Clusters (RAC) configuration, you must manually upgrade all RAC-associated hosts. You can use -allhosts to perform the rolling upgrade of all the hosts.

The following command performs the rolling upgrade of all the target databases mounted on the hosts, hostA and hostB and a repository database named repoA located on repo_host:

smsap repository rollingupgrade
    -repository
      -dbname repoA
      -host repo_host
      -login
       -username repouser
       -port 1521
     -upgradehost hostA,hostB

To perform a rolling upgrade on all the hosts on a repository database, enter the following command: smsaprepository rollingupgrade-repository-dbnamerepo_service_name-hostrepo_host-login-usernamerepo_username-portrepo_port-allhosts-force [-quiet | -verbose]

After successfully upgrading the repository database, you can perform all the SnapManager operations on the target database.

The following command performs the rolling upgrade of all the target databases available on a repository database named repoA located on repo_host:

smsap repository rollingupgrade
    -repository
      -dbname repoA
      -host repo_host
      -login
       -username repouser
       -port 1521
      -allhosts

If the SnapManager server starts automatically, you must restart the server to ensure that you can view the schedules.

If you upgrade one of the two related hosts, you must upgrade the second host after upgrading the first.

For example, if you have created a clone from host A to host B or mounted a backup from host A to host B, the hosts A and B are related to each other. When you upgrade host A, a warning message is displayed asking you to upgrade the host B soon after upgrading host A.

The warning messages are displayed even though the clone is deleted or the backup is unmounted from host B during the rolling upgrade of host A. This is because metadata exists in the repository for the operations performed on the remote host.
