Finalize

Introduction

Finalize allows to complete the migration by transferring the final piece of data and backlogs.

Performing Finalize

Finalize in Tranzman refers to the stage where all catalog components are migrated, and the environments can be finalised.
During this process objects are deactivated on the origin and activated on the destination. Objects here refer to the Media Servers, Storage Servers, Robotic Devices , Storage units , Policies, Clients etc.

Preparing to Finalize

Below steps helps prepare for Finalize with minimal downtime.

• Ensure a latest QueryImages job completed (last run < 60 mins) and rerun it manually (a few hours before the planned switch-over time).
  

If the frequency of the jobs is the same as the interval defined in Actions, then it is a good indication that things are ready to proceed.

• Tranzman provides visual representation of percentage of completed configuration.
• The progress bar available against all the configurations must be 100% to perform Finalize Destination
• Please refer Host Management if the Host Reachable or Hosts Promoted are not 100%.
• Image Queue should show 100% (this may drop as soon as the Init finalize is run as it will release images that are Pending Update which are typically the pending SLP operations for those images.
  

A large number of pending SLP images increases the overall switch-over period.

• If Query Config queue is not 100%, run a QueryConfig to discover for any new policies created since the last run which in turn perform a Create Workloads or Create Config(incase cyclic workload is chosen in Tunables) Actions.

Finalizing Origin

Clicking on the Finalize Origin Run button allows -

• Tranzman to deactivate Origin policies and SLPs.
• Tranzman then waits for any active jobs to be completed or cancelled. Ensure any active jobs are completed or cancelled through NetBackup GUI
• Once all the active jobs are cancelled/completed, Tranzman will deactivate any media servers being migrated.
• New QueryImages is started to pick-up any new images that have been written since the last scan. Wait for it to complete.

Working on Backlogs/Queues

Images as Pending Update will extend the switchover period. To reduce the window, the following can be performed before the planned switch-over date:

• Suspend secondary SLP operations on the Origin for all the SLPs that are selected for migration.
• Initiate Finalize and wait for the backlog to be transferred (Image Queue should show 100%)

QueryImages jobs will be set to manual when Init Finalize run, it is required to re-enable it in System->Actions until the day of switch-over

The backlog may now be larger on the Destination and ensure it can complete!!!

• Make sure that the ImageQueue is at 100%, this may be reduced because of SLP images being released into the Queue, or because the last QueryImages identified any new content.
• Initiate the CreateWorkloads to tell Tranzman to create / update any policies that are selected but are not already migrated.

Config Queue should then report 100%. If it is below 100%, then verify the Workloads (policies) or other Configuration Objects that are not imported and ensure to complete the configurations manually, if required.

• Rerun CreateMedia if Media Queue is not 100%. Ignore it, if no tape medias are used in Origin.

Media Queue will show 0% until Init Finalize is initiated.

Host Promoted

• The Hosts Promoted will show the percentage of hosts that has the Destination master added as the first entry in SERVER section.
• Use HostManagement to update all Client and Media Servers to have the Destination server as the master.
• Skip the update by using the toggle if needed. Perform this only if the Queue contains CLIENTS and not media servers.
  

Any media servers MUST be updated as this will also update the EMMSERVER entry to new master name which is required.

Finalize Destination

• By Default Finalizing the Destination will activate all SLPs and Policies. This can be deferred until the post checks are completed, by switching the Activation of Policies and SLPs from Auto to Delayed.
• Click on the Run button to finalize the destination, this will re-enable any migrated Media Server. It will also demote the Origin (if demote is selected) and will re-activate the SLPS and Policies (if not set to delayed).

If delayed activation is enabled, an additional row provides option to manually run it. This step can be completed whenever required.
