OnCommand Performance Manager migration to OnCommand Unified Manager fails


Background: 

Recently, the OnCommand Unified Manager (OCUM) was upgraded to 7.2. After upgrade, OnCommand Performance Manager (OCPM) data from 7.1 instance was migrated to OCUM 7.2.
The following document was used to perform the migration.
https://www.netapp.com/us/media/tr-4589.pdf


Issue: 

The migration process was reported as FAILED . One easy way to find out what caused the failure is to re-run the migration. As you re-run the migration, the workflow will show what caused the previous job to fail. Please note the cause of the failure

Alternatively, you can generate a support bundle (KB is here) and review the migration.log under JBOSS directory of the support bundle.

Resolution: 

Based on the cause of the failure, you can use one of the following KBs:


Migrating performance data to OnCommand Unified Manager 7.2RC1 shows status 'FAILED':

Performance data migration fails between OnCommand Performance Manager and Unified Manager 7.2x due to error java.io.EOFException: unexpected end of stream:

CommVault V11 SP update : error Required package [56] are not present

Recently, a CommVault customer requested an update of their CommVault environment from v11 SP10 to SP12. While the upgrade of the CommServe was successful, the upgrade of the media agent failed with the following error: 
"Required package(s) [56] are not present in current DVD. Record a new custom package with all required packages." 

A lot of time was spent on verifying if the procedure used to download the software package was correct. Later CommVault support identified that the antivirus software was blocking an MSI file at the following location:
<Software Cache>\DownloadPackageLocation2\DownloadPackageLocation_WinX64\BinaryPayload\NetworkStorageServer.msi 

Fix:

The antivirus software on the server(media agent) was configured to exclude CommVault directories and that helped resolve the issue. Here is the document that I followed:

CommVault VM restore : VM Blue Screens (BSOD)

Recently, a CommVault customer requested a VM restore. The routine browse and restore procedure was used to restore the VM successfully. However, the restored VM would blue screen when powered on. 

hmmm... was the VM not backed up properly ? Is the restore procedure right ? Are we missing/ ignoring a flag ?  These were some questions that needed answer.  

but ... CommVault support looked at the issue and identified it to be a bug in V11 SP10 and suggested an upgrade to SP12. (note: there is a workaround available in SP10).
