Can iquery operate on multiple interfaces?
This conversation suggests it is possible: https://devcentral.f5.com/s/feed/0D51T00006j3OvySAE
However, when we added more IPs to the servers in the server list, we saw intermittent failures to update pool member status when taking VS's up/down.
Is it possible that 'gtm_add <remote gtm additional address>' is needed?
This is the problem we are trying to solve:
- a set of GTM/LTM in two data centers, DC-A and DC-B, hosting apps balanced across data centers
- iquery traffic traverses a WAN between DC-A and DC-B
- WAN failure will cause a "split brain" situation when the GTMs can't "see" each other or the distant LTM
- It is important to know that WAN failure will cause the apps in DC-B to fail. That failure should cause the GTM in DC-B to assign traffic to DC-A. But with the WAN down, the DC-B GTM can't "see" the GTM/LTM in DC-A. It "thinks" apps in both DCs are down, so any queries on DC-B GTM for WIPs fail.
Does anyone know if iquery can operate on multiple interfaces, and if an additional gtm_add is required?
TIA
