Creation of mirrored Zpool in Solaris 11.4

-
In this blogpost we will see how we can create a mirrored zpool for the newly added hard disks. One of our customer upgraded the capacity of Oracle S7-2L Servers and we need to provision the new zpool for the newly added devices. Check the newly connected drives:
