9 Test the inactive Core, then switch Cores and test the other side:
SCPU
TEST CPU
10 Get the status of the CP cards and memory and of the CNIs:
STAT CPU
STAT CNI

11 Load overlay 137 and synchronize the hard disks. To be sure the contents
of the CMDU 1 are copied to the CMDU 0, verify that the CMDU 0 is
disabled:
LD 137
STAT
SYNC
Note: Synchronization may take up to 30 minutes.
12 Get the status of the CMDUs and be sure the CMDU 0 is active. Switch

13 In the Configuration Record (LD 17), add LD 135 and LD 137 to the
midnight routines. Remove LD 35, but leave LD 37 selected.
14 Insert a B1 database disk into each IOP/CMDU for backup. Load overlay

backups on both hard disks when redundancy is in effect (the hard disks
are synchronized) and the floppy on the active IOP/CMDU if a disk is
installed:
