Re: Rackswitch G8124-E and DS2200 connection

IP data cleared up

Ports 1-4 are copper SFP's and are attached to my hosts (2 to each)

Ports 5-8 are fiber and are attached to the SAN (iSCSI)

From my switch (using data, IP of 192.168.69.51), I can ping to the SAN on ports A0/1 and B0/1 (192.168.69.46 for A0 and 192.168.69.48 for B0).

From my SAN (CLI), I am unable to ping anything 192.168.69.x. Is there a command like "data" for the switch that specifys which port to use?

From my hosts (ESXi SSH) I can ping my switch (192.168.69.51), but not my SAN

Re: Rackswitch G8124-E and DS2200 connection

Hello,

 

In your current configuration (layer 2 single VLAN) the switch just uses normal L2 switching to decide where to send packets. It makes decisions based on learned MAC addresses, and if it does not know a given MAC, it will flood the packet out all ports. Can I get you to do the following from the switch:

1) Log into the switch and set you emulator to log all session output from the switch (how to do this depends on your emulator, but if your emulator does not support logging, just copy and paste the output to a file as you go)

2) From the switch, ping (with keyword “data”) the IP address of each and every device connected to ports 1-8

3) Run the commands “show mac” and “show ip arp” to see learned MACs and resolved IP addresses to MAC addresses

4) Post the entire log of the pings and the output of the commands to this forum thread.

 

Thanks, Matt

Re: Rackswitch G8124-E and DS2200 connection

See attached

 

IPs 100-101 are on ports 1/2

Ports 3/4 I'm ignoring for now as it's a duplicate server with ESXi installed

It's intermittent now being able to poing my host on port 1/2 for some reason

 

Ports 5-8 are my SAN iSCSI ports

Re: Rackswitch G8124-E and DS2200 connection

When you say "IPs 100-101 are on ports 1/2" Can you provide specifics? In other words:

Are these two different ESX servers (one on port 1 and one on port 2)?

Or is this a single ESX server with 2 NICs going to ports 1 and 2?

Are IPs 100 and 101 on a VM on the ESX host, or are they the vmk management ports for the ESX host(s)?

Do you have the NICs in the ESX host in two different vSwitches, or 2 NICs on one vSwitch?

Are you setting any VLANs on the portgroups or vmk ports on the vSwitch?

Every thing you can tell me about EXACTLY how the ESX hosts networking is configured will help.

 

Thanks, Matt

Re: Rackswitch G8124-E and DS2200 connection

IPs 100/101 are on 2 different VSwitches on the same ESXi host

I'm attempting to create/configure iSCSI configs in VMWare using those switches

No VLANs anywhere as there are no VLan's tagged on the switch

Re: Rackswitch G8124-E and DS2200 connection

1) I did not see the results of pinging to 192.168.69.47. Can you ping .47 from the switch and post the results and a fresh "show ip arp" and "show mac"?

2) Can you share a screen shot of the ESX vSwitch vmkport for both .100 and .101?

 

3) From the ESX CLI, can you ping 192.168.69.51 (the switch IP, post the output/results. And right after go to the switch and run the commands "show mp packet parse rx port 1" and "show mp packet parse rx port 2"

 

Thanks, Matt

Re: Rackswitch G8124-E and DS2200 connection

It would appear that after disabling and re-enabling my iSCSI adapter(s) on ESXi, I can now see/ping/access storage

 

Running a few more tests, but looks like this one might be solved. I'll report back shortly
