Boot system from CD.  modify /etc/system and /etc/vfstab to boot without veritas. Also comment startup scripts for veritas in /etc/rcS.d
Boot system in single user mode and then remove patches one by one.
Depends on the nature of the "crash".  If the server is bootable, bring up in single user mode and remove the patch with

patchrm <patch id>
