A CWD command was issued to change the current working directory to dsname data set was an existing MVS™ data set that was migrated. The FTP server needed to recall the data set in order to determine whether or not the data set was a partitioned data set. The recall of migrated data set dsname failed.
The server attempts to recall the data set, but the recall is unsuccessful. The current working directory is not changed.
Contact the system programmer.
Determine why the recall of the migrated data set failed and correct the problem.
