Hi Kiran, 

Thanks- just some background - we have a product called SAE - Secure agile exchange which is on top of NSO/NFVO and it has GUI and we are adding a device from that GUI. Looks like that device is not present on NSO device list and when we did a Sync on it we getting a timeout -instead of device not present. Thanks - we will add the device to netsim.

Before sync from please check the device is present on netsim or not, the device should be alive and started in ncs
to check same use this command >> ncs-netsim is-alive

if it is not present there, follow below steps to add same and sync it

1.create netsim device >> i have added device as TEST_ASA1

#ncs-netsim add-device packages/cisco-asa-cli-6.9 TEST_ASA1
DEVICE TEST_ASA1 CREATED

2.start the netsim device
# ncs-netsim start TEST_ASA1
DEVICE TEST_ASA1 OK STARTED

3. To check if it is added or not
# ncs-netsim list

we need to fetch ssh key to avoid sync from error

4. Fetch SSH key for the device
admin@ncs# devices device TEST_ASA1 ssh fetch-host-keys

5. run below command to sync
admin@ncs# devices device TEST_ASA1 sync-from

To check the device is sync or not run below command

#request devices fetch-ssh-host-keys

This is how i have resolved the issue with the help of kiran

Thank you Kiran:)
