we need to fdisk the partition of the second drive with:
pfexec fdisk -B c13t1d1s0
Copy label from the original rpool member
pfexec prtvtoc /dev/rdsk/c13t1d0s0 | pfexec fmthard -s - /dev/rdsk/c13t1d1s0
Attach mirror drive to the pool
zpool attach -f rpool c13t1d0s0 c13t1d1s0
Install grub on the second drive.
installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c13t1d1s0

iscsi target isn’t configured out of the box with omnios, you need to install the target:
root@omnios:~# pkg install pkg:/network/iscsi/target
then enable
root@omnios:~# svcadm enable stmf
omnios showmount: RPC: Program not registered

Comments Off on omnios showmount: RPC: Program not registered
On a vanilla install of omnios, shutdown command fails due to the system being unable to execute showmount.
To resolve this issue you must enable NFS which also requires that you share a directory, below are the steps involved:
echo 'share -F nfs -o ro=test -d "test directory" /export/home' >> /etc/dfs/dfstab
svcadm enable network/nfs/server
to ensure this has worked correctly execute
showmount
this should not return any errors.. simply execute shutdown and you should be back on your way!
