B.2.6 How to Resolve Conflicts With the DID Major Number

1. Choose a number that does not conflict with any other entry in the /etc/name_to_major file.

2. Edit the /etc/name_to_major file on each node and change the DID entry to the number you chose.

3. On each node where the /etc/name_to_major file was updated, execute the following commands.

   phys-hahost1# rm -rf /devices/pseudo/did* /dev/did phys-hahost1# reboot -- -r ...

4. On the node used to run the scdidadm(1M) command, execute the following commands.

   phys-hahost3# rm -f /etc/did.conf phys-hahost3# scdidadm -r

   This procedure resolves mapping conflicts and reconfigures the cluster with the new mappings.
