Is it possible to modify the FCS database information on an MDS switch? We have a 5 switch fabric which we are monitoring with ECC 5.2 SP5. We recently changed the IP address of the mgmt0 port on some of the switches in the fabric but ECC still shows the old address in Properties and in StorageScope reports. If you rediscover the switch using the new IP address it updates, but then seems to change the properties of the other switches in the fabric - it seems to pick up the IP address of the other switches from somewhere in the MDS. I'm guessing it queries the FCS database - when I query it from the MDS CLI, it shows two Switch MGMT-Addresses - the new one and the old one. You end up going round in circles. You rediscover switch A which corrects the IP address but changes switch B to the old address. You then rediscover switch B which corrects that one but changes switch A back to its old address. It took me a day of thinking I was going mad to find out what was happening!
