NetBackup 10.1 AIX Client Direct backups fail STATUS 83

Problem

NetBackup supports IBM AIX (RS6000) as a client.  One of the client features called ' Client Direct ' (client side deduplication), which has the ability to send data directly from a client to the MSDP/PureDisk storage, sending only the modified data which reduces the data across the network.

NetBackup 10.0.0.1 and previous versions perform Client Direct backups successfully, however, installing/upgrading to NetBackup 10.1 and above, the backups may start to fail with STATUS 83 when using Client Direct.   Note, all other backups are working as expected.

Cause

There were compiler upgrades for Client Direct deduplication software for NetBackup 10.1 on AIX/RS6000 build hosts.   These updates were related to new TCPIP refreshing features introduced which have the dependency for C++ runtime libraries xlC16.1.0.7 (and above). 
 

Solution

The AIX/RS6000 host will need updated C++ runtime drivers, if Client Direct backups are required.  An example of supported versions are;

# lslpp -L | grep -i c++
  libc++.rte               16.1.0.10    C     F    IBM XL C++ Runtime for AIX 7.1
  xlC.aix61.rte            16.1.0.10    C     F    IBM XL C++ Runtime for AIX 6.1
  xlC.rte                  16.1.0.10    C     F    IBM XL C++ Runtime for AIX
