NetBackup 8.0 / 3.0 Hotfix - MSDP MD5-SHA256 FP pre-conversion (Etrack 3956406)
Abstract
Description
Veritas Bug ID: ET 3956406
Version: NetBackup 8.0
Installation Location: Server
Problem Description:
A hotfix is available for NetBackup 8.0 MSDP which is an MSDP Pre-Fingerprint conversion EEB to remediate 8.1+ upgrade conversion performance degradation and excessive space consumption.
NetBackup 8.1+ changes the MSDP fingerprint algorithm from MD5 to SHA2 which brings some performance issues in a upgraded system.
The idea behind this new solution is to make a NetBackup 8.0 EEB, with this EEB, MSDP will generate FP mapping files in the background before upgrading to NetBackup 8.1+.
After upgrading the media server to NetBackup 8.1+ and applying the 8.1+ EEB bundle(3935219 for 8.1, 3942191 for 8.1.1, 3956103 for 8.1.2), MSDP can use these FP Mapping files to reduce the performance downgrade of FP changes.
Fixes Included:
8.0 MSDP Pre-Fingerprint conversion EEB to remediate 8.1+ upgrade conversion performance degradation and excessive space consumption
Also included in Version 6:
ET 3935874: Storage discrepency between 2 sites
ET 3920243: After upgrade disk pool keeps going down with multi threaded agents timed out errors - similar to ET 3916879
ET 3924548: AIR Replication rate is slower than bandwithlimit setting
ET 3990312: Enhancement for accurate MSDP conversion rate
More details can be reviewed in this knowledge base article.

Note: Depending on the size of the MSDP storage, this pre-fingerprint conversion should be installed/started 1 to 2 months prior to an attempt to upgrade to NetBackup 8.1.+
Installation Instructions:
The upgrade process has been divided into these steps:
Step 1: Install the HotFix on the 8.0 server(s).
Step 2: Run normal jobs with 8.0 pre-conversion hotfix in place. Check the conversion progress every several days and be certain the percent complete value is increasing. Use the command "crcontrol --fpconvertstate" to check the progress. The output will show the percent complete.
Step 3: When the total progress of the conversion shows it is %100, upgrade to 8.1+ and immediately apply the associated 8.1+ MSDP EEB Bundle
Detailed Instructions:
- Stop NBU service
- Apply this EEB.
- Start NBU service.
- Using "crcontrol --fpconvertstate" to check FP conversion progress.
- When the progress is 100%, upgrade to NetBackup 8.1+.
- Stop NBU service.
- Apply 8.1+ EEB bundle(3935219 for 8.1, 3942191 for 8.1.1, 3956103 for 8.1.2).
- Start NBU service.
- Wait spoold cache loading by checking the following message in spoold.log.
=== spoold.log ===
ThreadMain: Data Store nodes have completed cache loading(Complete Cache).
10. Run backups. For data that has not changed, the dedup ratio should be close to 100%.
