Booting OpenVMS from CD-R Media?

» close window

The Question is:

 
Dear Wizard,
 
after searching in de FQA's I stll have a question. We try to create a bootable
 CD of VMS and some tools.
We create a file with .iso structure but ... no able to boot from the disk.
We get the following error during boot.
 
? T_ERR_SCSI - CHECK_BOOTBLOCK
 
What indicate there is NO valid boot block.
Do you have / know who to fix this ?.
 
(Note: make the .iso file "bootable" ? )
 
Thanks,

The Answer is :

 
  Neither OpenVMS VAX nor OpenVMS Alpha systems bootstrap from
  ISO-9660 disks.  (It is possible for ISO-9660 disk structures
  to overlay with bootable ODS-2 or ODS-5 disk structures, which
  may be the source of your confusion.  But OpenVMS boots from
  ODS-2 or ODS-5 structures.)
 
  If you want to see how an OpenVMS CD is built, look at the OpenVMS
  distribution kit and at the provided DCL command procedure
  (SYS$SYSTEM:AXPVMS$PCSI_INSTALL_MIN.COM) that generates a bootable
  disk.  Your target disk is clearly lacking a bootblock, meaning
  that WRITEBOOT was not run against the source of the partition.
 
  Create such a PCSI installation disk in an LD-based (or your own
  prefered disk partition tool) partition.  Burn it using CDRECORD
  (or your prefered CD recording tool).  Boot it.
 
  The OpenVMS Wizard would tend to avoid Windows CD recording tools,
  as these can increase the confusion should they not perform a raw
  block burn -- the OpenVMS Wizard prefers to use OpenVMS Freeware
  and a direct-attached SCSI or ATA/ATAPI CD-R device.
