Comment 2 for bug 1842945

Here is an additional scenario where there is a bad error message returned:
hw (ironpass 20-27)
1. 2 controllers installed (unlocked, enabled and available)
Note: The following command was used to set the replication factory (after install of controller-0)
$system storage-backend-modify <name> replication=3 min_replication=1
2. Attempt system storage-backend-modify operation to update the min_replication value to 2
(before or after controller-1 has been installed)

Result:
inadequate error message returned as follows:
$ system storage-backend-modify ceph-store replication=3 min_replication=2
'replication'
