Hi.
I am trying to move the root volume from an existing svm mirror to a zfs
root. The machine is a Sun V880 (SPARC) running nv_96, with OBP version
4.22.34 which is AFAICT the latest.
The svm mirror was constructed as follows
/
d4 m 18GB d14
d14 s 35GB c1t0d0s0
d24 s 35GB c1t1d0s0
swap
d3 m 16GB d13
d13 s 16GB c1t0d0s3
d13 s 16GB c1t1d0s3
/var
d5 m 8.0GB d15
d15 s 16GB c1t0d0s1
d25 s 16GB c1t1d0s1
I removed c1t1d0 from the mirror:
# metadetach d4 d24
# metaclear d24
# metadetach d3 d23
# metaclear d23
# metadetach d5 d25
# metaclear s25
then removed the metadb from c1d1d0s7
# metadb -d c1t1d0s7
Resized s0 on c1t1d0 to include the whole disc and relabelled with an
SMI label.
Created the zfs root pool:
# zpool create rpool c1t1d0s0
Created new BE:
# lucreate -c Sol11_b96 -n Sol11_b96_zfs -p rpool
This ran fine, so I activated the new BE and rebooted
# luactivate Sol11_b96_zfs
# init 6
The system then panicked during the reboot with:
Rebooting with command: boot
Boot device: /pci at 8,600000/SUNW,qlc at 2/fp at 0,0/disk at

syncing file systems... done
skipping system dump - no dump device configured
rebooting...
It then cycles the reboot and panic until I pull the disc and reboot
continues from the original boot disc.
Any ideas why mounting root on zfs is apparently not supported?

You can try doing this by hand, with the command: installboot -F zfs /usr/platform/`uname -m`/lib/fs/zfs/bootblk /dev/rdsk/c1t1d0s0 But if live upgrade was unable to do that already, there may be other issues to uncover once you actually do boot.
