Install IOS-XE and eWLC simultaneously

[anthony.wild]

Hello All,

We currently operate SDA with a number of deployments that utilize FIAB or switches that have the wireless role enabled. We are currently hitting a bug to where DNA SWIM is incorrectly calculating the available space on the target switch and thus failing the workflow.

In the interim while we work to resolve, can someone please help identify the sequence of commands needed to install both the target IOS-XE release and also the wireless subpackage? DNA would usually do this automatically, ensuring that the switch would not reboot between steps. What are the commands to achieve this manually, so that we don't inadvertently reboot a switch that has the wireless role, without the dependent subpackage. I've scoured reddit, forums, and install guides and not seen this specifically covered.. so I apologize if this is published somewhere and I missed it. 

Thank you in advance!

upload all needed images on the target switch
install add file flash:<baseimage> act com //switch will reboot then
install add file flash:<package|apsp> act com //switch may reboot as well. depends on package

Hi there. I think this will work if we can accept the reboot after the base image. However, if the wireless role is on the switch, then we want the subpackage to be installed at the same time. DNA SWIM is able to do this somehow to where both install at the same time so that when the reboot occurs, lines of code that reference wireless configuration will work due to the presence of the subpackage. If you look at the screenshot, you can see the "addons" referencing that dependent subpackage. I'm just not sure what the secret sauce or commands are that makes that work.

there are no mystery behind SWIM background interactions with switch. it do the same what u would do. eWLC subpackage gets installed after base image is installed. doing stuff manually u can play with activate & commit phases for base image & eWLC subpackages making both base & eWLC coexist in certain phase. but if transitions between phases for either of them requires reboot u wont avoid it. thus simultaneous "installation" of base image & eWLC subpackage doesnt make much sense.
