As you have release 6, read the following below.
Problem
Unable to join CPU.
Cannot Join, the redundant partition is not synced, try CUTOVER first.
SRPT046 LCS: Cannot Join, the redundant partition is not synced, try CUTOVER first.

Solution
Remove 'inactive.dr', under '/e' drive, on both hard disks.
The file may only be shown on the active CPU
to remove (On Rel 6 anyway)
cd /e
del inactive.dr
The system will then allow you JOIN the system
All the best
