Are you stuck in same situation where your guest ldom root file system is full and VM went into the transition mode? Then this is the right technical article that will help you to overcome this issue. We encountered this issue in one of our customer environments and were able to fix it successfully.

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.
