NimbostratusHi Ben,
Before making any changes to a remote devices configuration (on the BIG-IQ system), I always resolve configuration differences in these two areas:
1) Between the imported configuration and the LTM (deployment evaluation).
2) Between the members of a DSC device group.
Deployments have always failed for me when the DSC group is out of sync, but I always select both devices to update. It would be good to test a single device in the DSC group.
Hope this is somewhat helpful,
Kevin
Quick update to my post after a quick check:
1) BIG-IQ forces you to select both devices when deploying to a DSC group. 2) My deployments were failing because I didn't override the out of sync condition:
Under Devices tab
Select the device under Device Name
Look under Cluster properties.
Hit Edit and look for:
X Initiate BIG-IP DSC sync when deploying configuration changes. (Recommended)
o Allow deployment when DSC configured devices have changes pending. (Not Recommended)
Hit the second check-box and you can deploy to an out of sync device group.
Sounds like a bad idea which is probably why this isn't checked or recommended.
Hope this is helpful!
Kevin
