This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Install In-Service Software Update Using Horizon
|
|
================================================
|
|
|
|
The procedure for applying an in-service update is similar to that of a
|
|
reboot-required update, except that the host does not need to be locked and
|
|
unlocked as part of applying the update.
|
|

|
|
|
|
#. Log in to the Horizon Web interface as the **admin** user.
|
|
|
|
#. In |prod| Horizon, open the Software Management page.
|
|
|
|
The **Software Management** page is available from **Admin** \> **Platform**
|
|
\> **Software Management** in the left-hand pane.
|
|
|
|
#. Select the **Patches** tab to see the current update status.
|
|
|
|
The **Patches** tab shows the current status of all updates uploaded to the
|
|
system. If there are no updates, an empty **Patch Table** is displayed.
|
|
|
|
#. Upload the update (patch) file to the update storage area.
|
|
|
|
Click the **Upload Patch** button to display an upload window from which
|
|
you can browse your workstation's file system to select the update file.
|
|
Click the **Upload Patch** button once the selection is done.
|
|
|
|
The update file is transferred to the Active Controller and is copied to
|
|
the update storage area, but it has yet to be applied to the cluster. This
|
|
is reflected in the **Patches** tab.
|
|
|
|
#. Apply the update.
|
|
|
|
Click the **Apply Patch** button associated with the update. Alternatively,
|
|
select the update first using the selection boxes on the left, and then
|
|
click the **Apply Patches** button at the top. You can use this selection
|
|
process to apply all updates, or a selected subset, in a single operation.
|
|
|
|
The **Patches** tab is updated to report the update to be in the
|
|
*Partial-Apply* state.
|
|
|
|
#. Install the update on controller-0.
|
|
|
|
#. Select the **Hosts** tab.
|
|
|
|
The **Hosts** tab on the **Host Inventory** page reflects the new status
|
|
of the hosts with respect to the new update state. In this example, the
|
|
update only applies to controller software, as can be seen by the
|
|
worker host's status field being empty, indicating that it is 'patch
|
|
current'.
|
|
|
|
.. image:: figures/ekn1453233538504.png
|
|
|
|
#. Select the Install Patches option from the **Edit Host** button
|
|
associated with controller-0 to install the update.
|
|
|
|
A confirmation window is presented giving you a last opportunity to
|
|
cancel the operation before proceeding.
|
|
|
|
#. Repeat the steps 6 a,b, above with controller-1 to install the update
|
|
on controller-1.
|
|
|
|
#. Repeat the steps 6 a,b above for the worker and/or storage hosts (if
|
|
present).
|
|
|
|
This step does not apply for |prod| Simplex or Duplex systems.
|
|
|
|
#. Verify the state of the update.
|
|
|
|
Visit the **Patches** tab again. The update is now in the *Applied* state.
|
|
|
|
.. rubric:: |result|
|
|
|
|
The update is now applied, and all affected hosts have been updated.
