The OLT is the Object Location Table in fileset1 of the VxFS header. There is a primary OLT and a copy of it. The OLT contains structural information about the filesystem that is used at mount time. If both copies are corrupt, your filesystem can probably not be repaired. You might want to try if a "fsck -F vxfs -o full /dev/vgora1/rlvol1" can possibly fix it. See the manual page fsck_vxfs. If it cannot be fixed by a full fsck, you need to newfs the filesystem and restore your backup.
In any case you should check the underlying hardware for problems.
