+==== Disk issue ====
+So on nexenta one of our disk failed and require to be replace.\\
+Dell sent us lager drive than original drive.\\
+PERC required to clear managed cache, once it is cleared i was able to create new VD for new drive.\\
+While creating VD please make sure you choose the size same as working VD.\\
+It is required when you copy the slice from working drive, else it will error.\\
+FIXME 'Partition 0 not aligned on cylinder boundary'.\\
+There are way to add larger size but i took the fastest route after so many problems.\\
+After adding new drive there are certain steps i had to do before i can add it to the syspool.\\
+First clear and scan all the drives on box.
+<code bash>
+devfsadm -C -c disk -v
+devfsadm -c disk -v
+</code>
+Check if your newly added drives added.
+<code bash>
+echo |format | head -10
+</code>
+:!:You can ignore using head, mine was c0t0d0 which was fist in the list.
+Fdisk new drive, but some time it error 'Partition 0 of the disk has an incorrect offset'.\\
+I had to do it multiple times.\\
+<code bash>
+pfexec fdisk /dev/rdsk/c0t0d0s0
+</code>
+Now its time to replicate slices.
+<code bash>
+prtvtoc /dev/dsk/c0t1d0s0 |fmthard -s - /dev/rdsk/c0t0d0s0
+</code>
+Now attache the drive to zpool mirror, it is require to specify existing mirror drive as source.\\
+<code bash>
+zpool attach -f syspool c0t1d0s0 c0t0d0s0
+</code>
+It should tell you to run installgrub.
+<code bash>
+installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t0d0s0
+</code>
+Wait for resilvering before you reboot the server.
