About installing a hotfix
We provide an F5® iWorkflow™ hotfix to meet a need or resolve an issue unique to your environment. F5 recommends that you run iWorkflow in a cluster. When applying a hotfix to an iWorkflow cluster, you must first evict the peers from the cluster (breaking the cluster) and then apply the hotfix to each instance before recreating the cluster.
To install a hotfix, make sure that you have:
- Adequate disk space available to complete the installation.
- Administrator rights on the iWorkflow system.
- A recent user configuration set (UCS) backup of the iWorkflow system copied to a remote secure server for storage.
- An iWorkflow release ISO file copied to the /shared/images directory.
- A target iWorkflow base ISO available under the /shared/images directory.
Breaking a cluster
Before you start, make sure that you are running an iWorkflow™
cluster.
You break the cluster in order for removed peers to return to a default state.
Important: If you are running a standalone system (your environment
contains a single iWorkflow server), skip all the steps for Breaking a cluster.
Proceed to Installing a hotfix on a standalone
system.
Note: When you break a cluster, the data stored on the peer that is evicted
from the cluster will be lost.
Installing a hotfix on a standalone system
Before you start, make sure you are running a standalone system. That is, your
environment is running a single iWorkflow™ server.
Important: If you are installing a hotfix on an iWorkflow cluster, you must
first break the cluster before installing the hotfix on each iWorkflow instance. If
you have an iWorkflow cluster, first perform the Breaking the a cluster
procedure before you start this procedure.
You can install a hotfix to meet a need or resolve an issue unique to your environment.
Note: While you are updating the iWorkflow server, it is not available for
administrative access. You cannot make changes, updates, or additions to any of the
managed BIG-IP® systems. However, traffic on BIG-IP systems is
not impacted.
Recreating a cluster
Before you start, make sure that the peers joining the cluster are clean
builds.
You can recreate a cluster from any iWorkflow™ instance.
Important: The cluster creation process does not support importing existing
configurations from an existing iWorkflow system.
- Log in to the iWorkflow administrative user interface with your administrator user name and password.
- At the top of the screen, click System settings.
- From the iWorkflow Cluster panel, in the iWorkflow Cluster header, click the plus (+) icon.
- In the New iWorkflow Cluster Member panel, type the IP address, Admin Username, and Password.
- Click OK to acknowledge the data on the peer will be overwritten warning.
- Repeat this procedure for the third iWorkflow member in the cluster.
