Here is the scenario:
I have three 3Com 4200G series switches. I have 8 servers. All servers
are HP Proliant DL380, 360, or 320 servers. All servers are connected to
the same 3COM switch. I have 2 APC Smart-UPS 5000 RM XL. These are plugged
into the same 3COM switch. I'm having an issue in which some of the servers
can ping both of these APC devices, some can only ping 1 of the APC devices,
and some cannot ping either of them. All servers can ping each other. I
can't figure out why some of the servers can ping the APC devices and some
can't. It doesn't make any sense. The 3COM switches are not specifically
configured for anything special. All ports are the standard default settings,
and set to Auto-negotiate. I can't find anything in the APC Network Card
Mgmt interfaces that would need to be configured to allow pings from a certain
server. One thing to note is that from the APC Interface, I also can't ping
the server that has the communication problem with the APC device. It's
like they are blocking each other or something. Also, it would seem that
one of the servers can't even ping the network switch that it is plugged
into, but can ping the other 2 switches just fine.
The Windows firewall is not running on the servers. I'm not sure if there
is still some specific port(s) being blocked. When I have configured the
servers from scratch, I always use the HP SmartStart CD. After the OS is
installed, there is a window that pops up talking about whether or not you
want to open all the server ports. I thought I had always hit yes, but I'm
wondering if I didn't or something, and I have no idea how to get that window
to pop back up. Is there a registry setting on the server that I can change
to allow all traffic without using the Windows Firewall config? I did actually
start the Windows firewall/ICS service so I could check to allow ping requests
and such, then I disabled it again, but that didn't do anything for me.
I'm really stumped. I am going to try and move one of the problem servers
to a new port on the switch to see if that makes a difference. Unfortunately,
this site is remote, and I have to have one of my people there do that in
the morning. It definitely could be some goofy setting with the 3Com, and
I might have to call 3Com support, but just curious if anyone might have
seen this before with 3COM switches?
Thanks,
Sara
