symcli command for VMAX operations.
VMAX3 lun decom, we need to free all devs to delete

symdev -sid 123-devs 028F free -all

*************************************

lun id reset command 

If we wish to remove this identity, this is a disruptive process. You can do the following to reset the identity:

1. Take devices offline to the host and then remove them from their current storage group
2. Issue the command: ‘symdev set -no_identity <dev>’ against each device
3. Add the devices back to the storage group and rescan on the host
4. Confirm that the correct identity is now seen in syminq
