Automation does the writelog command at midnight and starts an STC. That STC is an external writer that picks up the syslog from class L (which is unique to syslog output in the spool) and writes the syslog to a disk GDG. After the "idle" message from the external writer, automation stops the external writer. The next step in STC copies the disk gdg to a tape GDG. In sysplex environments, one of the LPARs is chosen per sysplex to have additional steps to dump the operlog to disk and copy to tape. The GDG limit controls the retention of disk files, tape may be controlled by GDG limit an / or tape mgmt system retention period control (may not be the same everywhere). In a few of the LPARs, the disk GDG retention is set more than 3 or 4 GDGs but HSM migrates those to ML1 (the GDG limit is not high enough to where they ever end up on ML2). This is quicker than recall from virtual tape that is not in the buffer. Oh... in shared spool environments the writelog / STC only executes on one LPAR and I have a REXX exec I wrote that splits off the syslog into separate LPARs. This was so we didn't have to dedicate a different class per LPAR for the syslog. Back in "the day" output classes were hard to come by.
