Do you get to the GRUB menu while booting from the larger drive (then you can try verbose and/or mdb boots to Solaris and catch its panic errors), or does the machine reboot before even getting to GRUB?
Couple of "silly questions": 1) Did you "installgrub" onto the second drive? 2) Are you certain your BIOS supports booting from a 2Tb device and MBR partition? Or with that size it should be a GPT partition, probably, which should emulate an empty(?) MBR table... So try to see if that text involves something about a missing boot device or an empty hard-disk, etc. Enabling your BIOS to pause on boot errors (known by the funny message "Keyboard not found, press F1 to continue booting") can help to read the error. Otherwise you can try to quickly press the PAUSE key to pause the BIOS output and SPACE to go on booting. Alternate both to try and catch teh error string... _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
