Reclaiming Disk Space
Follow the steps in this section to reclaim the disk space that was reserved for converting virtual machines.
These instructions assume that you have performed the upgrade procedure described in
Steelhead EX Software” on page 16
.
By default, the upgrade process does not automatically alter the existing disk layout. Disk space must be
manually reclaimed.
Note:
Changing the disk layout erases Granite and VSP data from the disk and destroys the ESXi datastore. The
appliance is rebooted as part of the process. Back up your Granite, VSP, and datastore data prior to changing the disk
layout.
For details about the amount of space that can be recovered, and about maximum allocations, see
EX xx60 Technical Specifications” on page 59

to confirm your intention to change the disk layout and reboot the device.
Downgrading the Software
If you want to downgrade to a previous version of the Steelhead appliance software, you must downgrade
to a version of the software that has previously run on your machine.
When you downgrade the software, RiOS reverts the ESXi version to the version supported in the
installation image. If you upgraded the ESXi by using vCenter (separate from the EX installation), the state
cannot be restored and ESXi starts with the initial configuration.
