IT33509: SUPPORTED VERSIONS OF SMB PROTOCOL ARE NOT DOCUMENTED.

APAR status

• Closed as program error.

Error description

• The document section "Backup network file systems" mentions
  behaviors of the Linux client with NFS and CIFS (SMBv1)
  protocols.
  However, as CIFS (SMBv1) is deprecated, the manual should
  document all supported SMB protocols versions as well as any
  restrictions about unsupported SMB protocol versions.
  
  
  IBM Spectrum Protect Versions Affected:
  All supported versions of IBM Tivoli Storage Manager and
  Spectrum Protect Backup-Archive Client on Linux platform
  
  
  Initial Impact:
  Low
  
  
  Additional Keywords:
  TS003821194, TSM
  

Local fix

• The recommendation is to mount filesystem explicitly with the
  SMBv3 protocol version for NFS and CIFS shares.

Problem conclusion

• 1. Query command will report correct file system type in case of
  backup SMB version 2.002, SMB version 2.1, and SMB version 3.0.
  2. The section "Backup network file systems" will include
  information about supported versions of CIFS.
