Upgrade from PSW 2.2 to ISHP-W 2.2.2 Causes Temporary Network Disruption

Technote (FAQ)


Question

Will your network connection be affected when you update Proventia Server for Windows 2.2 to IBM Security Host Protection for Windows 2.2.2?

Cause

During the upgrade, our issnfh driver is replaced. This requires that we stop the Network Interface Card drivers, insert our new driver and then restart the NIC drivers.

Answer

This driver replacement can have unintended consequences. At the least, there will be a temporary loss of the server's network connection lasting a few seconds as the NIC is restarted. At worst, it can cause disruption of cluster services and possibly cause a change in the binding order the NICs on the server.

Because of this, we strongly suggest that you install this upgrade during a change control window and closely monitor it for any possible side effects. Treat this as if it were a new application installation.
