SyncIQ networking problem
Two clusters on the same subnet and domain, both members of the domain, both accessible in all normal manners, But SyncIQ is failing:
SyncIQ is unable to connect to a resource on the target cluster.
Used ping to determine if target is reachable.
Verified that SyncIQ is licensed and enabled on the target cluster, and that the SyncIQ daemons are running.
Error from remote sworker 10.7.153.50: Local cluster has no external IP addresses
The policy is targeting the SmartConnect Name, which is pingable from that cluster.
Thoughts???

We got this semi-sorted by restricting target ifaces to those in a SC zone. There are a couple of possibilities as far as why this was needed, but since this is a demo and not production we didn't pursue.

Any chance this is a dynamic pool?
From the User Guide:
Type the Name or address value carefully; the system does not validate the data that you enter.
Note: SyncIQ does not support dynamic pools.
It’s a nasty little gotcha.
Oh, the other thing I hadn’t remembered to ask. Any address translation (NAT) going on here in their network? I ask because of the address you quote which is in one of the private address ranges (10.0.0.0/8).

Just a thought : Check if you used a 10.x.x.x adresses for the internal InfinniBand interfaces when the cluster was initially setup.
