I would like to run a test recovery of a client index save set. Is it possible 
to do this without using nsrck? I don't want to recover it to the actual 
location on the backup server (Linux RH). In fact, I want to recover it to a 
different machine, and then recover the same save set from a clone volume and 
compare the two results. The only reason for doing this is to corroborate that 
the data is the same on both volumes. Yes, I could pick a non-index save set to 
test instead, and I've done that many times, but I'd like to try an index save 
set.

I've never done this before. The only time I've ever recovered an index was 
when I really needed to recover it, in which case I used nsrck. So what happens 
if you do a save set recover (CLI recover) of an index on another machine, not 
the server? If this won't work then can you use scanner with uasm to do a raw 
recovery on the storage node?

Indices can't be recovered in the way that you're describing. Well, not since 
v6, anyway.

The only way to test an index recovery outside of your current backup server is 
to setup a test server with an identical hostname (indices are tied to the name 
of the backup server), and do a test recovery in a bubble.


Hmm ... Well, I guess that's not surprising. So even running this on the snode wouldn't work:

cd /disk2/test
scanner -S ssid_value_of_index /dev/nst# | uasm -rv

or some such thing? It's smart enough to know that you're trying to recover an index and won't allow it?

George

Cheers,
