Thanks for all the feedback on this.
I was sort of hoping that the server might do some sort of integrity check
on startup and tell me that there are 'n' corrupt files giving me the
option of starting up without them - sort of like spool does.
Unfortunately, from the feedback, it appears there

Part of a DR procedure is running an exec that regenerates all SFS
servers
How long does yours take?
Takes an annoyingly long time - nearly an hour - to regenerate an 90G
filepool.
If we didn't do disaster tests monthly, it wouldn't be so bad, but what
the heck could it be doing for an hour?!

included the SFS servers. At the DR site, things came up fine for about
5

Is there not an installation option to change the filepool name? If not,
there should be.
If you are referring to the filepool and directory the RMS control and
configuration files must reside on, yes you can move them by
creating a UCOMDIR NAMES file on the RMSMASTR 191 minidisk, for example:
Can you do the same for the filepool that RMSMASTR wants his work and log
directories in? Like this:
