EqualLogic not using default gateway - can't access from remote subnet
I have spent all day trying to configure my new 6510's and just can't access the group or management IP remotely. I have gone through the setup procedures multiple times and still can't get it to work. I can only access the group or management IP address if I am connected locally to the switch on the same vlan. I cannot ping the default gateway. I can ping each member and locally connected devices on the same VLAN. I have used the guides on here to enable the management interface from the cli and I still have the same behavior, its like there is no default gateway or the array does not use it.
If i connect my management laptop directly to the switch on the same VLAN, I can access the group and it would seem like nothing is wrong, everything is working correctly and all the network information including the default gateway appears to be correct. Other devices on the same switch and vlan like my management laptop work fine and can ping to the default gateway.
Has anyone run into this problem before?

Don,
I used the grpparams def-mgmt-gateway ipaddress xx.xx.xx.xx cli commands in the guide here en.community.dell.com/.../20169735.aspx
When i log into the GUI, it shows everything is configured correctly.
My management ports are connected to a 3750 and the iSCSI ports are going to Nexus 5548.

I looked at the link you provided, and I noticed that this was only how to check if the management network was configure. However a few items are omitted in that post to fully enable the management network. Here is a quick guide to getting the management network working.
First, you need to ensure the managment network is configured on the highest eth interface for each member in the group (or use the dedicated management interface for arrays that have one, like the 10g models).
grpparams management-network show
(This verifies if the management network is active or not).
If configured the display will show you a management group IP address, this is different than the iSCSI group ip address.
Next on each eth interface that will be used for the management (again this is the highest interface for each member), and assign a IP address that is in the same subnet as the management group IP address.
member select member_name
eth select 3
(or the highest eth interface or the dedicated management eth port)
show
(just to see what it looks like now, if configured)
Configure the ip
Eth select 3 ipaddres ip_address netmase net_mask
Up the interface
Eth select eht 3 up
Set the interface for management only
Eth select 3 mgmt-only enable
Show
(you should new see the IP entry is on the management subnet, and that the management network is set to yes.
Do this on all the members
Now once all eths are setup, configure the grpparams for the management network (only done once):
grpparams management-network ipaddress ip_address
grpparams def-mgmt-gateway ip_address
Note, to verify the management network gateway, is configured, you need to go into the GUI, select highlight the eth interface on each member and the summary will show the mgt def-gateway.
You many need to down then up the eth interface(s) if in your review you need to make any changes.
