Bulk Data Copy causes server hang

DL380 G3 (W2K3 SP1) which operates fine under normal conditions. However if a bulk copy of data is transferred to it, the server grinds to a halt and prevents all connectivity.

Have performed HP diagnostics on array, all successful. Need to upgrade all firmware and support packs.

Just wondered if anyone had encountered a similar issue and isolated a cause?

Hi Bob,

That sounds like its going to be something related to the network as opposed to the drive array.

What switch are you connected to ?
Can you see any errors on the switch port ?

Re: Bulk Data Copy causes server hang


I've recently had this problem on one of my servers. In my case, it turns out that the NIC windows driver was auto-negotiating a wrong connection type for some reason that didn't sit well with the switch. So, a manualy selected a connection speed of 100 full dupl. And that did the trick.

But in past experiences, it could be a defective NIC driver or the NIC itself, the patch cable not well connected or damaged or the port on the switch.

Try eliminating these out.

Re: Bulk Data Copy causes server hang

Thanks guys.

Just recommended updating the support pack, which will cover the drivers.

It's a Cisco Switch with both port and card set to Auto so I'll reconfigure these to fixed settings.

I've also recommended configuring perfmon so I should start getting some results back soon.

I'll let you know the results.
