I'd faced NDMP backup problem with one CIFS file system where security descriptor size has exceeded 32KB which is limited for NDMP backups by default. There is a Primus solution: emc134597 which suggests to change the pax parameter “maxCifsBufferLengthInKB” from default 32 kb to 64 kb whereas the maximum value could be 128 kb. But I'm not able to find the parameter. Infact following command output reveals the parameter "maxCifsBufferLengthInKB" as unsupported argument. Our current DART version is 5.6.51-3.  [admin[NAME] ~]$ server_param server_2 -facility PAX -info maxCifsBufferLengthInKB server_2 : Error 2111: server_2 : Unsupported argument: maxCifsBufferLengthInKB  Can anyone guide me how to set this to 64KB ?
