Re: Steps for adding new volumes - I seem to be missing a step (or two)
|
I realy don't recall how DMGR is started or where it gets a list of disks. I haven't thought about this in around 30 years. I do know that the list of MTS volumes is stored in a table called (I think) DSKTAB in the TABLES assembly and that there is at least one dummy entry at the end of this table where a new volume can be patched in. I'm also pretty sure that's all that is needed to get the new volumes to work with MTS. It shouldn't be hard to patch this table using RAMROD to see if I'm right.
As a minor bit of trivia, this table dates from some time in 1966 back when 6 character names were still the norm (because 6 characters fit in one word on a 704 or derivative).

Got it working - Thanks

There has to be some way in the startup jobs to tell DMGR what volumes to add (actually disks – like D400, D401, etc) . I hope that’s not hardcoded in the system deck (like timezone).
?
Been looking around on INIT and STRT and can’t find where DMGR is started. The only thing I see in the startup messages on the console makes me think DMGR is started when PDP mentions it for paging.

I suppose I can run SYS:DSK from one of the INIT scripts.

I think so. After the ADD, do a DMGR:
ADD MTS601
DMGR MTS601
...
If I remember well, the additions are "temporary", you will need to run SYS:DSK again to (re-) add your disks after each IPL.
