Upgrade considerations regarding MSDP fingerprint algorithm changes
Because of the changes in the fingerprint algorithm for MSDP in NetBackup 8.1, consider your MSDP environment as you plan your upgrade path. Any NetBackup 8.0 and older host cannot access the NetBackup 8.1 MSDP because of the new fingerprint algorithm. Failed NetBackup jobs can result from a failure to plan for this condition.
For more information, refer to the NetBackup Upgrade Guide for NetBackup 8.1.
