GSLB and INC mode
« on: July 29, 2010, 06:22:48 AM »
GSLB... and INC Mode HA...

Has anybody ever successfully configured a GSLB site at an INCmode HA pair?

I am finding initially that the site information is lost but have solved that by binding the GSLB site to a local SNIP, in INC mode SNIPs are node specific and therefore the GSLB site on the secondary must be set as another IP address i.e. another SNIP.  Therefore the HA pair becomes two GSLB sites....

Thinking that is messy is the start, then add services...  in short you can but as HA occurs so the data is lost as the services are not referenced properly.

Does anyone have a working example...

Hey Bratster,

Any reason for you're using INC mode?  I found it to be unnecessary quite frankly.  I normally break the HA pair and recreate them with INC disabled whenever possible.

But if you HAVE to keep them that way, then yes.  Your individual boxes will have unique SNIP, NSIP, and MIP.  They can share VIPs, which is where you'd bind your LB and CSLBs anyway.  The secondary node will not respond to the VIP requests, so the GSLB config will see it as an offline site until it becomes primary..

I have done a configuration where the client had two ISP and we used GSLB to load balance the ISPs, but the HA pair had the same configuration.

You GSLB'ed the providers for outbound traffic only of course.  So did you create redundant VIPs with different IPs and planned to switch DNS if one failed?
