Re: NT4 Cluster change to new SAN

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

To add more fuel to your fire, consider (with your customer) that support
for NT4 is gone for all intents and purposes and this new SAN equipment
purchase provides the ideal opportunity to address these legacy systems.
Additionally, NT4 clusters are notoriously difficult to work with...you
don't even want to sneeze around those boxes for fear of disaster....

Strongly encourage the customer to purchase new servers running W2K3 for
their new nodes and if they continue to insist on trying to move the NT4
systems, run away very fast. :)
