cannot label 'c0t5000CCA0251EF65Cd0': EFI labeled devices are not supported on root pools
I'm running Solaris 10 u9. I just applied the April quarterly patch cluster. I'm trying to mirror the boot disk which is using zfs, something I've done before w/o problems prior to the patch cluster install.
Code:
disk=c0t5000CCA0251D9514d0;mirrordisk=c0t5000CCA0251EF65Cd0;echo $disk $mirrordisk
c0t5000CCA0251D9514d0 c0t5000CCA0251EF65Cd0
prtvtoc /dev/dsk/${disk}s2 > /tmp/disk-partitionTbl
fmthard -s /tmp/disk-partitionTbl /dev/rdsk/${mirrordisk}s2
fmthard: New volume table of contents now in place.
zpool attach -f rpool $disk $mirrordisk
cannot label 'c0t5000CCA0251EF65Cd0': EFI labeled devices are not supported on root pools.

A disk that is intended for a ZFS root pool must be created with an SMI label, not an EFI label.
You can relabel a disk with an SMI label by using the format -e command.
format -e c0t5000CCA0251EF65Cd0
selecting c0t5000CCA0251EF65Cd0: solaris
[disk formatted]

I am having trouble understanding the difference between a passthrough device and a named device and when you would use one or the other to access equipment.
As an example, we have a tape library and giving the command
"camcontrol devlist" gives the following output:

Hello,
I'm brand new to Sun/Solaris.
I have a Sun Blade 150, with SunOS 5.8.
I wanted to make a backup to prevent future data loss, so I put the disk in a normal PC with Windows XP to try to make a backup with Norton Ghost, the disk was detected, but not the file volume, so I place the disk... (6 Replies)
Hi All!
I have been tasked with creating a clustered file system for two systems running Sol 10 u8. These systems have 3 zones each and the global zone has ZFS on the boot disk. We currently have one system sharing an NFS mount to both of these systems.

Hi,
I'm trying to get a Flash Archive Jumpstart Running with ZFS Filesystem. For Testing I set up a VirtualBox VM with 2 Disks attached.
