[OpenIndiana-discuss] OI server failed overnight - some help restoring it!

[Carl Brewer]

G'day,
I have an OI server from ~2 years or so ago that went down overnight - 
it has 5 HDDs, 2 as a ZFS mirror (root) and 3 as a ZFS raidz array.  I 
can see all 5 drives when I boot off an OI USB boot image, but I can't 
see anything more than the output from format, which sees that all 5 exist.

zfs list etc don't show me anything

Is there a way to try and mount these drives onto the USB boot image and 
inspect them? Maybe I have a corrupted boot block or something?

Thank you

Carl
