zfs discuss - Jan 2009 - How do you "re-attach" a 3 disk RAIDZ array to a new OS installation?

Hi,

I''m completely new to Solaris, but have managed to bumble through
installing it to a single disk, creating an additional 3 disk RAIDZ array and
then copying over data from a separate NTFS formatted disk onto the array using
NTFS-3G.

However, the single disk that was used for the OS installation has since died
(it was very old) and I have had to reinstall 2008.11 from scratch onto a new
disk.  I would like to retain the data on those 3 disks (the RAIDZ array) and
"reattach" (what''s the correct terminology here?) them to the
new OS installation without losing any data.

As I''m unsure of the terminology I should be using I''ve been
unable to find anything by searching either online or in the forums.  Any
assistance would be greatly received, thanks :)

Luke,

You''re looking for a `zpool list`, followed by a `zpool import  
<poolname>` after Solaris has correctly recognised the attachment of  
the three original disks (ie. they appear in `format` and/or `cfgadm - 
al`).

Complete docs here, now you know what you are looking for ...

zpool import

Without any other arguments will show what pools are available for import.

Then run zpool import again with the name of the pool or the pool guid.
