Unable to copy using cp command in AIX

Question

I am trying to copy directories recursively using cp -R command in AIX, however certain directories(related to ITDS and DB2 Instance) like SQLT0000.0/SQL00123.DAT, SQLT0000.0/SQL00123.DAT, and SQLT0000.0/SQL00123.INX are not getting copied and give error:

Invalid argument

Below is the output of truss command:

Answer 1

Try to copy one of this files individually, to find out if the problem is file-specific. If so, check if the file-path containts something problematic, like a symlink to a not-readable directory.

Also you can try 'truss' to find out the system-call that fails (open/read/write etc) -- not for beginners though.

Answer 2

Yes i have tried to copy that particular files. some file SQL00xyz.INX or SQL00xyz.DAT files are copied and some giving invalid argument error
