Hoping someone can recommend some direction for a peculiar issue we're seeing.
In our View 6.2 environment, we have the following structure:
Overall site GTM via F5, we'll call it connectvdi.site.com
DC1:
5 Internal View Brokers - All 5 Behind a Site LTM, we'll call dc1-connectvdi.site.com
2 External View Brokers
DC2:
5 Internal View Brokers - All 5 Behind a Site LTM, we'll call it dc2-connectvdi.site.com
2 External View Brokers
The F5 setup is completely load balanced. We have onsite Wyse 5010 ThinOS w/ PCoIP terminals all configured to go to the GTM, which then load balances to the LTMs. Quite randomly, we will see the Wyse terminals boot up and land at their login with all boxes grayed out with a message of "Contacting Authentication Server...". After no specific time, they will eventually come back and present you with normal login credential boxes. If the terminal is connected already to View, they run fine, they do not get interrupted.
While the issue is happening, we've troubleshot several scenarios and have it narrowed down as such:
- Pointing the terminals to the DC1 LTM, they all continue to work without issue. No problem whatsoever.
- Pointing the terminals to the DC2 LTM, the issue persists. It does NOT work as a resolution bypassing the GTM.
- Pointing the terminals to the DC2 View brokers 1 at a time via FQDN does NOT work either. Issue persists.
- Pointing the terminals to the DC2 view brokers 1 at a time via IP DOES resolve the issue. Suddenly they start to work.
While all this is going on, pings look fine, nslookups resolve no problem, tracerts seem to behave as expected, etc. We can't spot something specific. It looks obvious that it's a DC2 issue, but, we have 3 other Wyse terminal platforms: V10L (ThinOS), and R50 and D50D terminals (SUSE Linux). None of these terminals exhibit the same problems as the 5010. The network guys blame Dell, and the Dell guys blame the network.
My reason for posting here is to see if the DC2 view brokers could be the issue for whatever reason. I've compared them side by side with DC1, and I can't spot an issue. Not sure anyone has a setup even close to what we're doing, but, if anyone has a similar experience, I'd appreciate some feedback.
Thanks in advance.
