IBM SAN DS 3512 Controllers Networking issues
On the SAN there are 2 controllers
3 Hosts present
Controller A Ip addressing
10.50.60.101 Working with Ping to Host and on Switch
10.50.61.101 Not Working to Host but shows on DS manager on SAN as connected and configured
controller B
10.50.60.102 Not Working to Host but shows on DS manager on SAN as connected and configured
10.50.61.102 Working to ping from all Hosts
Have had a person in the server room unplug port which is NOT working configure laptop to same range of IP addressing and it does not ping or get an Active link on the laptop NIC.
Whats is weird if you configure one port that is NOT Working with a diffrent IP addressing
Like controller port 192.168.133.60 and laptop NIC 192.168.133.63 The link on the laptop card lights up and ping requests works
We are baffled
Possibly a restart of both controllers ?? or any other help appreciated

Can you ping that IP on other physical interface?

Hi
No, cannot
No, cannot
Can you afford unplugging "working" port while other is plugged?

Unfortunately Not at this stage if i do that the laod on the the one controller will be too much and then we will loose the presented volumes on the hosts .
Do you run vmware certified firmwares?

Or ones for your client OS-es ?

The environment has HyperV 2012
Would there be a way to have a look at the controllers networking via a command line to see if there are some sort of a configuration that can be seen not working as it should be?

We have also on IBM advice updated the firmware on the controllers but still no joy

Ok post firmware and IBM onsite to check the San Controllers which checked all good
Everything is pointing back to the cisco switches. Would there be anything special from a storage (IBM) perspective that needs to be configured on the switch port ?
