My jumpstart install uncompresses the flar but leaves the server without bootblock or zfs bootpool, to fix this i install the bootblock and set the zpool’s bootfs property
# zpool status
pool: rpool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c0t0d0s0 ONLINE 0 0 0
c0t1d0s0 ONLINE 0 0 0
# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t0d0s0
# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0
# zpool set bootfs=rpool/ROOT/sol10u11sparc rpool
Then just… reboot
