We have recently installed Solaris 7 on a virgin disk on SCSI 0 (c0t0d0s0 is the root partition). The disk that was previously on SCSI 0 was moved to SCSI 1 (which is now c0t1d0s0). We wanted to preserve this disk because it contains Solaris 2.6 and software that is only supported under 2.6 . If we want to boot from disk1 now, Solaris 2.6, as opposed to the Solaris 7 disk, disk0, how do I reformat this disk so it will recognize the proper partitions and boot? I thought all I would have to do is modify the /etc/vfstab file (change c0t0d0s0 to c0t1d0s0, etc...). On boot I get the message "Can't open /dev/rdsk/c0t1d0s0". The system tells me to run fsck -F ufs /dev/rdsk/c0t1d0s0 - I do but the system can't open that device. Please help and thanks in advance.
