Dear All, Thank you for comment. I don't believe the thumper does have a fault. We bought the machines direct off Sun as "factory refurbished" and we negotiated a very good price. And yes, indeed we have warantee and indeed we have paid for longer support than the standard time.
As I commented at the end of my post, I do indeed have the one thumper that I have worked on running fine with OpenSolaris 2009.06. The two boot disks had a slightly odd label written to them I believe which caused the initial "Bad PBR sig". I have relabelled both boot disks and I have them running fine as a mirrored ZFS root pool. However, it does seem to me that OpenSolaris 2009.06 autoinstall does have a problem with thumpers as I reported. As I commented, I managed to load OpenSolaris 2009.06 fine from an external DVD drive. So, I go back to my one of my earlier questions: Has anyone sucessfully autoinstalled OpenSolaris 2009.06 onto a x4500/thumper?? Dave Price -- This message posted from opensolaris.org
