NONEXPR mounting CD-ROM in ISO 9660?

» close window

The Question is:

 
We loaded openvms 7.1 1H2 on a alpha server. I can not mount a cdrom with
ISO 9660 format. It gives me the following error. %mount-f-nonexpr,
nonexistent process.
 
Thank you
 
 


The Answer is :

 
  When mounting the ISO 9660 CD-ROM, an ancillary control process (ACP)
  must be created.  It would appear this process is failing, or is not
  starting.
 
  Please check the format of the CD-ROM media as a start, typically either
  ISO 9660 or High Sierra format is used for the CD-ROM.
 
  Check the system accounting log, to determine if the process is starting
  and then failing for some reason.  Limitations based on the maximum
  number of processes permitted on the OpenVMS system (MAXPROCESSCNT) and
  similar problems have been known to prevent the ACP from starting up.
 
  Though you do not mention the specific type of CD-ROM drive nor the
  host system involved, the use of OpenVMS Alpha V7.1-1H2 would tend to
  imply the system may be a DIGITAL Personal Workstation, and potentially
  one with the IDE CD-ROM drive.  There is a known problem in the IDE
  CD-ROM support in V7.1-1H2, and the explicit specification of the ACP is
  required: use /PROCESSOR=F11CACP for ISO 9660 media, and for media in the
  High Sierra format use /PROCESSOR=F11DACP.  This restriction is removed
  in OpenVMS Alpha V7.1-2.
 
  If explicit specification of the ACP does not resolve this problem,
  please contact the customer support center.  The specific type of Alpha
  system as well as the specific CD-ROM drive will be of interest here.
