For mirror we do error injection using the FP console command: dmiptest.

Can "fscmd crash_set" for mirror help if we use the option of looping
for so many ms or seconds at a particular point in the code? We're in
the process of going through those hooks to see which one have been
implemented, I don't know if anybody finishes the work that Xioabing had
started in this area.

It is important to test DMIP networking failures during each and every
state of the mirroring process.  This can be really difficult given that
some states don't last very long, but we definitely need to see whether
DMIP can survive a communications error on every RPC type that is sent
between sanmd(s) and between sanm-agents(s).  This may involve some
additional whitebox infrastructure to elongate the duration of those
states so that you can enable the network tool at the proper point in
the work flow.

We have setup a WAN emulator tool to simulate delays, packet drop,
packet loss... on DMIP link.

Please review the attached test cases. We'd like to get feedback for the
expected result marked as TBD and find out if more scenarios need to be
covered.

Mandatory reviewers are QA team, Mike, Danqing and Ranga.

Please copy Sangeetha for comments.

Thanks,
