20 Parameter Update Rollback

Allows an update on the parameters to be set back to its previous state.

1. Copy the upgrade file (zdlra_release.zip) to the Recovery Appliance compute server into the /radump/ directory.

   scp zdlra_release.zip oracle@zdlraadm01:/radump/

2. As a user in the raadmin group, run various checks to verify that the Recovery Appliance is in a healthy and stable state before. Refer to Running Recovery Appliance Checks. As an example:

   [adminra1@zdlra05 ~]# racli list check --status=enabled
   check_active_incidents
   check_appliance_status
   check_cell_alerts
   check_compute_alerts
   check_image_versions
   check_init_parameter
   check_invalid_objects
   check_ra_export
   check_ra_version
   [adminra1@zdlra05 ~]#

   [adminra1@zdlra05 ~]# racli run check --check_name=check_active_incidents,check_invalid_objects
   Wed Oct 10 13:53:07 2018: Start: racli run check --check_name=check_active_incidents,check_invalid_objects
   HOST: [nnnnnn01.oracle.com]
   
   Created log file scas10adm01.us.oracle.com:/opt/oracle.RecoveryAppliance/log/racli_run_check_20181010.1353.log
   Wed Oct 10 13:53:07 2018: CHECK: Active Incidents - PASS
   Wed Oct 10 13:53:09 2018: CHECK: Invalid Objects - PASS
   Wed Oct 10 13:53:09 2018: End: racli run check --check_name=check_active_incidents,check_invalid_objects
   HOST: [nnnnnn01.oracle.com]
   [adminra1@zdlra05 ~]#

   You can selectively run other checks, or all enabled checks with racli run check --all.

   Pay particular attention to any checks that FAIL, because they may indicate that the Recovery Appliance is not in an appropriate state to continue with the upgrade operation.

3. On the compute sever, navigate into the /radump/directory and unzip the upgrade file.

   [adminra1@zdlra05 ~]# cd /radump/
   [adminra1@zdlra05 radump]# unzip zdlra_release.zip
   

4. As a user in the raadmin group, run the following command from the /radump directory.

   [adminra1@zdlra05 radump]# /usr/bin/perl ra_preinstall.pl
   

   Pay attention to any validations that failed , because they may indicate that the Recovery Appliance is not in an appropriate state to continue.

5. As a user in the raadmin group, run the following command from the /radump directory.

   [adminra1@zdlra05 radump]# /usr/bin/perl ra_preinstall.pl --rollback
   

   Pay attention to any validations that failed , because they may indicate that the Recovery Appliance is not in an appropriate state to continue.

6. Validate the ZDLRA version that was installed on the Recovery Appliance.

   [adminra1@zdlra05 radump]# /opt/oracle.RecoveryAppliance/bin/racli version
   

7. Validate the ZDLRA services are online.

   [adminra1@zdlra05 radump]# /opt/oracle.RecoveryAppliance/bin/racli status appliance
   

8. Validate the health of the Recovery Appliance.

   [adminra1@zdlra05 radump]# /opt/oracle.RecoveryAppliance/bin/racli run check --all
