If one removes physical access to a majority of the voting disks then Oracle corp predicts that
CSS will mark the disk as stale * . Since there is no quorum, the clusterware will stop.
CSS will evict the nodes because there is no quorum. - On reboot, the system should restart and wait without CSS – also because there is no quorum.
After quorum is restored, crsctl start crs should restore the clusterware stacks. Reboot should not be required.
* this will be mentioned in a trace files ..see example of Solaris 8 following a RAC node reboot under a (very) heavy CPU and memory load. There is in the trace file below:

This is a timeout after a 282,535s polling on the voting disk. IO errors were neither reported in /var/adm/messages nor by the storage array.
