    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>

    Let me explain the complete detail:
    0. Complete backup wastaken
    1. The rootdg is mirrored with Veritas
    2. Before pathcing the mirror was deleted
    3.But while matching the mirror was reattached by mistake and both the disks are patched and now is down.
    Please let me know how to bring back the system from backup.

    Accepted Solution

    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.
