Trying to boot Alpha,

Specs: VMS
Alpha has 4 hard drives, the fourth, dka300 will not mount.
The old drive does know it is USERDISK3, but will not mount.
I have a replacement drive if needed, but do not really need any info on dka300. The system is caught in a loop and will not continue booting up until the system recognizes the volume name USERDISK3 and mounts, which the new disk is not label as so.

Check the information at this URL:

http://labs.hoffmanlabs.com/node/204

Look for the sections on "Conversational Bootstrap on OpenVMS Alpha" and "SYSTARTUP_VMS.COM or such is failing".

Following these instructions should allow you to boot up just far enough to change the code that gets stuck in the loop. For instance, you might submit the mount command to a batch queue instead of doing it in the startup command procedure.

After making the change, reboot normally.

Good luck.

If the system is part of a cluster, and another cluster member has access to the booting members system disk, then just edit the offending command-file from there.

The command-files most probably containing the mount-loop are:
in sys$manager:
systartup_vms.com (or called from there like mount_disks.com).

sylogicals.com

If the disk in question is a local paging disk, then the mount is in either
SYPAGSWPFILES.COM
or SATELLITE_PAGE.COM in the systems sys$specific:[sysexe].
