Alike Services Do Not Start--SHA-1
If your A2 services no longer start, please drop to the shell (option 4) and type
if you receive a Java stack trace error which includes a SHA-1 message, then this indicates your A2 disk image has been corrupted.
The best intervention available is to provision a new A2 and reattach your ADS (and ODS) to it. After doing so, please self-service a license reset at portal.quadricsoftware.com and then reapply your licenses.
