831.0. "PCM 1.5 MUP 1 fails on strtup with an ACCVIO" by COMICS::BARLOWD () Tue Jun 20 1995 20:14

Hello all

Sorry the detail is sketchy the customer has little to go on.

the customer has shadowed (2 member) system disk. During the evening something
happened to change the state of the shadow set and a shadow merge occured.
On returning the next day the customer was unable to start PCM in any mode, it kept 
failing with an ACCVIO. This has worked previously but has only been installed for 
3 days. the installation was done a senior DEC Consultant. 

It was found that if you split the shadow set and boot from the 'secondary' disk
of the set the problem was recreatable. Booting from the 'primary' member of the 
set all was OK. The shadow set was then re-created with no further problems. 

Using SEt WATCH it was found that the ACCVIO occured when reading teh configuration 
file. Editing the config file on both disks uncovers nothing wrong.

Any ideas/hints/suggestions please. Again, te customer did not write down the 
full aCCVIO message and has lost what they had.

    Thats really wierd. PCM doesn't do anything out of the ordinary in
    terms of file operations at all. It's almost like the config file on
    the secondary member got munged. The verification process done by the
    editor can't catch everything. It's really there to make sure that
    things make logical sense. The only thing we could have done further
    was to pick the file apart on the primary and secondary members and
    look for corruption.

Thanks Dan. The customer has already verified that the file on the primary and secondary
members are not corrupted. They appear to be working now and just wanted an 
explanation for the initial problem. I will contact you if further info is requested.

TIA

    Indeed. You'll want to get 1.6 on ASAP as there won't be any more work
    done on the 1.5 code stream.
