MSDP conversion

Hi all, some weeks ago I upgraded Netbackup from 7.7.3 to 8.1 for a customer. During the installation, the system didn't asked me about the MSDP conversion process. The upgrade was completed witho...

    There are quite a number of docs that deal with pre-upgrade steps, pre-upgrade EEB, MSDP pre-conversion steps, post-upgrade EEB, etc. 
    Hopefully you have gone through all of that?

    https://www.veritas.com/content/support/en_US/doc/25074086-127355784-0/v122375353-127355784

    To determine the mode of data conversion and the conversion progress, use the --dataconvertstate option:

    Windows: install_path\Veritas\pdde\Crcontrol.exe --dataconvertstate

    UNIX: /usr/openv/pdde/pdcr/bin/crcontrol --dataconvertstate

Hi Marianne,

thanks for replying.

I already checked with these commands and this is the output:

./crcontrol --dataconvertstate
***** Data Conversion *****
Status : ON
Mode : Fast
Busy : Yes
Current Group ID : 15043
Current DCID : 15404071
Min Group ID : 0
Max Group ID : 15425
Progress : 18%

I also checked it with this command and seems that everything is ok

./stconv --status
Your Media Server Deduplication Pool is up to date

But maybe I found the answer to my question.

I read in this page https://www.veritas.com/content/support/en_US/doc/25074086-127355784-0/v122375349-127355784  that after the upgrade to 8.1, the data is re-encrypted with the AES-256 algorithm, so the data container has an additional .map file that contains the mapping between the SHA-512/256 and the MD5-like fingerprints.

Before posting this question, I checked only the last data container and there weren't .map files, but, in the previous data I can find them. That means that it is converting and everything could be ok.

Anyway, I still have the doubt about the fact that I was not asked about the conversion during the update, both from 7.7.3 to 8.0 and from 8.0 to 8.1. Next week i have to perform another similar upgrade. Are the command I used above (crcontrol --dataconvertstate and ./stconv --status) enough to be sure that is ok?

Thanks again

There is also 
crcontrol --fpconvertstate 
Not sure if the pre- and post upgrade EEB's are necessary for this switch as this option does not appear in Commands Ref Guide.

Output should look similar to this : (From  https://www.veritas.com/support/en_US/article.100045193  )

Monitor conversion until completed: 

# /usr/openv/pdde/pdcr/bin/crcontrol --fpconvertstate 
***** Fingerprint Conversion (MD5 to SHA256) ****** 
Status                    : ON 
Mode                      : Normal 
Busy                      : No 
Converted Prior DC count  : 0 
Total Prior DC Count      : 0 
Converted Normal DC Count : 10080 
Total Normal DC Count     : 10080 
Converted percentage      : 100.0%(total), 100.0%(prior), 100.0%(normal)

    Hi Marianne,

    yes, there is an EEB (https://www.veritas.com/support/en_US/article.100043154) that I already installed after the upgrade.

    The option you mentioned doesn't run but I can check it with the command

    ./crcontrol --dataconvertstate

    The conversion is in progress

    Thank you very much
