=head1 NAME fms.log - Records output from the fms command =head1 DESCRIPTION The F file records the output generated by the B command. The output includes two numbers that can appear in a tape device's entry in the F file on the Tape Coordinator machine to which the tape device is attached: =over 4 =item * The capacity in bytes of the tape in the device. =item * The size in bytes of the end-of-file (EOF) marks (often referred to simply as I) that the tape device writes. =back When transferring the numbers recorded in this file to the F file, adjust them as specified in L, to improve Tape Coordinator performance during dump operations. If the F file does not already exist in the current working directory, the B command interpreter creates it. In this case, the directory's mode bits must grant the C (read, write, and execute) permissions to the issuer of the command. If there is an existing file, the command interpreter overwrites it, so the file's mode bits need to grant only the B permission to the issuer of the B command. The B command interpreter also writes similar information to the standard output stream as it runs. The file is in ASCII format. To display its contents, log onto the client machine and use a text editor or a file display command such as the UNIX B command. By default, the mode bits on the F file grant the required C permission only to the owner (which is the local superuser C by default). =head1 OUTPUT The first few lines of the file provide a simple trace of the B command interpreter's actions, specifying (for example) how many blocks it wrote on the tape. The final two lines in the file specify tape capacity and filemark size in bytes, using the following format: Tape capacity is bytes File marks are bytes =head1 EXAMPLES The following example of the fms.log file specifies that the tape used during the execution of the B command had a capacity of 2,136,604,672 bytes, and that the tape device writes filemarks of size 1,910,220 bytes. fms test started wrote 130408 blocks Tape capacity is 2136604672 bytes File marks are 1910220 bytes =head1 SEE ALSO L, L =head1 COPYRIGHT IBM Corporation 2000.
