questions on DDB recync and convertddbTov5

Good day,

CS: V11.16.x

Before doing a hardware refresh for the CS, we created a VM in a lab with wins2019 and imported the CS DB during SP28 installation. 

all works fine. However, once login to the CommCell Console, we received a message indicating that the DDB was currently undergoing maintenance and required the completion of maintenance operations such as DDB resynchronization and conversion to a transactional DDB, among others.

we have 2 DDBs, and the "convertddbTov5" plan indicates that there are 2 Memdb that need to be converted to version 5. 

Questions: 

 

  1. if the DDB resynchronization will function as expected after the CS hardware refresh, as two of the DDBs are MemDBs that will need to be converted to V5 after the successful hardware refresh and DDB resynchronization.
  2. Which logs will display the DDB resynchronization status and process, does "sidbengine.log"?
  3. if the DDB resynchronization or the "convertddbTov5" operation will impose any restrictions on the ability to browse or restore data.

    thanks

HI @DanC ,


Good day!

 

Please find my below response. 

 

  1. if the DDB resynchronization will function as expected after the CS hardware refresh, as two of the DDBs are MemDBs that will need to be converted to V5 after the successful hardware refresh and DDB resynchronization.

    Yes, first you need to bring the DDB out of maintenance in order to convert them to non-mem db. If possible, covert them to non-mem db prior performing the CS refresh. 
     
  2. Which logs will display the DDB resynchronization status and process, does "sidbengine.log"?

    You can check the progress via MediaManager.log in CS. 
     
  3. if the DDB resynchronization or the "convertddbTov5" operation will impose any restrictions on the ability to browse or restore data.

    ​​​​​​​No. Restore operation doesn’t require the DDB to be in online.
