NetBackup 7.7.3 / 2.7.3 Hotfix - MSDP MD5-SHA256 Fingerprint Pre-conversion (Etrack 3964714)
Abstract
Description
Veritas Bug ID: ET 3964714
Version: NetBackup: 7.7.3
Problem Description:
A HotFix is available for 7.7.3 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 NetBackup 8.0 EEB, with this EEB, MSDP will generate FP mapping files in background before upgrading to NetBackup 8.1+.
After upgraded the system to NetBackup 8.1+, by 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.
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 Location: Server
Fixes Included: 7.7.3 MSDP Pre-Fingerprint conversion EEB to remediate 8.1+ upgrade conversion performance degradation and excessive space consumption
Version 3 also includes the following fixes:
ET 3948596: MSDP storage discrepency between the production and DR site.
ET 3936375: SO missing in DC
ET 3891282: data corruption has been detected
ET 3934793: Spoold is crashing and core dumping
ET 3893364: Images have been incorrectly marked as corrupt by data integrity checking
ET 3904271: Optimized Duplications failing with error 150, suspecting corruption on source storage server
ET 3990312: Enhancement for accurate MSDP conversion rate

Installation Instructions:
The upgrade process has been divided into these steps:
Step 1: Install the HotFix on the 7.7.3 server(s).
Step 2: Run normal jobs with 7.7.3 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:
1. Stop NBU service
2. Apply this EEB.
3. Start NBU service.
4. Using "crcontrol --fpconvertstate" to check FP conversion progress.
5. When the progress is 100%, upgrade to NetBackup 8.1+.
6. Stop NBU service.
7. Apply 8.1+ EEB bundle(3935219 for 8.1, 3942191 for 8.1.1, 3956103 for 8.1.2).
8. Start NBU service.
9. 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%.
