|
# and to install kdump with its further configuring on this instance.
|
|
# Here, the "light" version of functional test is proposed.
|
|
# It's based on knowledge that trigger-crash-dump uses a NMI injection,
|
|
# and when the 'trigger-crash-dump' operation is executed,
|
|
# instance's kernel receives the NMI signal, and an appropriate
|
|
# message will appear in the instance's log.
|

# The server status must be ACTIVE, PAUSED, RESCUED, RESIZED or ERROR.
|
|
# If not, the conflictingRequest(409) code is returned
