Speedup VAX-cluster startup-procedure
-------------------------------------
Booting our VAX-cluster takes too long. It takes approximately
20 minutes before we have all systems up and running from a
coldstart.
The first bottleneck is the meeting that the 3 VAXes seem to
have. Perhaps adding a quorum-disk can speedup that mumbling
about entering and leaving the cluster?
The second bottleneck is SYSTARTUP.COM itself. There are a lot
of software products that have to be handled. Some of them I
start up by submitting a job from batch. I edited one
command-procedure to startup jnet from batch and if there is a
problem I get a notification by MAIL from that
command-procedure.
The third bottleneck sometimes is the mount-verification of 10
RA81's if one of the systems was not shut down properly. I can
handle that by switching off mount-verification.
I am going to rewrite the startup-procedure. I want to
implement a multi-trap-rocket taking care of dependencies. For
example I should first startup DECnet and after that PSI. I
think of writing one command-procedure which can be called
with an argument indicating the command-procedure (eg.
CMSSTARTUP.COM) There should be some error-checking and
problems should be reported by MAIL using a distribution list
pointing to our system-managers.
SYSTARTUP.COM then could look like:
$...
$ @SUB_TO_BATCH CMSSTARTUP
$ @SUB_TO_BATCH ACMSTART
$ ...
Now for my question:
Anybody having some time-saving hints how to handle this all?
I know how to do it but every hint might save me some time. To
save you time reading boring remarks:
PLEASE respond directly (immediately?) to me and I'll
summarize back to INFO-VAX.
