AUTOMOUNT does not manage concatenation of root directory with files concatenation #286

Closed marXtevens closed 3 years ago

marXtevens commented 3 years ago

It appears that by making use of AUTOMOUNT to have a root directory, breaks the ability to actually attach an existing file to an OS, presenting an empty file instead.

This is from a current build of SDL-Hyperion. The information is in the attached log file.

I set up hard and symbolic links for a tape (AWS) file. The following are the hard and symbolic links on the host Linux for Hercules.

[xmas@vm370dev VM370]$ find /home -iname 'CUNY.aws' /home/xmas/Hercules/VM370/Tapes/_CUNYMODS.aws /home/xmas/Hercules/VM370/VM_370_Utilities/CUNY/_CUNYMODS.aws [xmas@vm370dev VM370]$ ls -l /home/xmas/Hercules/VM370/Tapes/_CUNYMODS.aws /home/xmas/Hercules/VM370/VM_370_Utilities/CUNY/_CUNYMODS.aws lrwxrwxrwx. 1 xmas xmas 61 Feb 8 14:37 /home/xmas/Hercules/VM370/Tapes/_CUNYMODS.aws -> /home/xmas/Hercules/VM370/VM_370_Utilities/CUNY/_CUNYMODS.aws -rw-r--r--. 1 xmas xmas 302718 May 22 2017 /home/xmas/Hercules/VM370/VM_370_Utilities/CUNY/_CUNYMODS.aws [xmas@vm370dev VM370]$

Log on as MAINT. Absolute path to the file via DEVINIT.

Screen scraping of MAINT console showing tape attached, and output from TAPE SCAN and TAPEMAP commands.

Tape detached and new file attached. This one uses symlink.

Again, screen scraping from MAINT console shows tape can be read by TAPMAP, and not by TAPE SCAN.

I set up AUTOMOUNT to the original file, DEVINIT shows an extra message this time: "HHC00235I 0:0580 Tape file _CUNYMODS.aws, type aws: tape created"

This time we see the tape is empty.
