P4500 G2 CMC Port?

I have my entire iSCSI storage network segmented off to a particular VLAN (primarily supporting a vSphere environment). I do not have, nor do I intend, to have any systems residing on the iSCSI VLAN with the exception of each storage node and ESXi servers.

So my question is, quite simply, I am going to install CMC on my management network, what port do I need to open on my iSCSI network in order to manage the storage nodes?

I found this thread:

It touches on the same gist of what I am asking, but it's not talking at all about managing across VLANs through a firewall rule.

The documentation guide does note port 8959 is required but then states it's for the CLI.

Any thoughts or guidance?

We installed CMC on our vcenter server. Our vcenter server is a virtual machine, so we added a second NIC and assigned it access to the iSCSI network through the VIC/vsphere client.

Works great.

Thanks for the reply. I understand what you did, but unfortunately we're at the mercy of very strict network segmentation requirements and could not bridge that vCenter across a management AND SAN networks.

I can't imagine we're the first ones to do this. We did get a PDF from HP and working with network administrators, decided to open the following ports (fyi for anyone else running into this problem):


The problem I am having now, is whenever I "IP" the 2nd Management NIC, it drops my entire CMC-to-Node connection. I'll have to do some research on that now...

Sounds like a routing problem if you add an IP address to a second interface and the connection then drops on the first one.
I would check the usual suspects like subnet mask or gateway address.
