PS6501e - Need to change Management IP Address

We have recently moved to a new HQ location and implemented a completely new IP scheme.

The Dell Equallogic SAN Management IP address is still set to the old IP settings. I am trying to change the Management IP address and gateway settings but when I do in the CLI I get the error: "Error - There must be at least one member network interface on the same subnet as the management address."

The NICs are set as follows:

ETH0 100.100.100.4

ETH1 100.100.100.5

ETH2 10.4.0.7

I need to change the management IP settings to the following:

IP - 10.96.5.50
Gateway - 10.96.5.1

Screenshot of all ETH interfaces below.

Two solutions

  1. You need your serial cable and disable the optional management and reconfigure it
  2. You disable the optional management within the GUI and have a system (a VM is great for that) around which than starts the GroupManager and connect to the WKA within the iSCSI subnet. The management will switch back into iSCSI if you disable it.

IIRC to configure it from cmd its something like

eth select 2 up
eth select 2 
ipaddress 192.168.1.101 netmask 255.255.255.0
grpparams
def-mgmt-gateway ipaddress 192.168.1.254
management-network ipaddress 192.168.1.100

@Origin3k​ 
I have tried those steps in the CLI with a serial cable. When I try to change the IP address (ipaddress 10.96.5.50 netmask 255.255.255.0) I get the error message "Error - There must be at least one member network interface on the same subnet as the management address."

I get the same message if I try to change the def-mgmt-gateway or the management-network ipaddress.

I cannot access the web interface because the original management IP isn't available. I have to go through CLI.

These are the commands I use:

eth select 2 up
eth select 2 
ipaddress 192.168.1.101 netmask 255.255.255.0
grpparams
def-mgmt-gateway ipaddress 192.168.1.254
management-network ipaddress 192.168.1.101


You mention disabling the optional management, how is that done? eth select 2 down?

Try "eth sel 2 mgmt-only disable " and "management-network ipaddress none".   You can verify is with the "eth sel 2 show "

Another way would be to "wide" the MASK of your MGMT depending on from which IP to where you need to go.

Please take notice a typo in my management-network ipaddress command. The MWKN needs for sure to be different compared to eth2.

Hello, 

 The easiest way to resolve this is to ADD and IPv6 IP address to the Dedicated mgmt port.   Then you will be able to change the IPv4 IP and subnet and gateway.  

 CLI>member select <MEMBER NAME>

CLI>eth selet 2 

CLI>ipv6address   XXXXXXX 

 Then you should be able to change the IPv4 address 

 The issue is the same as when you change the iSCSI ports.  At least one port has to be on the new IP subnet before you can move the well known Group IP address (WKA) or the Management Well Know Address  (MWKA) 

  Otherwise you have to disable Mgmt port entirely.   Then re-do it on the new subnet.  Since you are seria ported in you can use any valid IPv6 address, your never going to actually connect to it. 

 Regards, 

Don

The "trick" with using  ipv6address we need to use when dealing with the PS61x0 because this model only have one "iSCSI" port per CM.

Yes, it's the same issue.  There is only one physical port for Management also.   And if you have multiple ports for iSCSI but they are not yet enabled, then you will get the same error message for iSCSI too.

I've tried the steps to disable the management only but I keep getting the same error that one interface must be on the same subnet as the management interface.

I tried to set an ipv6 address, and it is set in there when I do eth sel 2 show but I get error about the subnet again when I try to change the eth 2 ipaddress.

I also now have access to the web interface of the SAN through the existing IP. I still cannot change the IP or subnet in the GUI. I get the same error.

I need assistance to get this done. I cannot believe Dell doesn't know how to change an IP address on their own equipment. Why is this so difficult to accomplish?
