Product description

Cloud administrators can use iWorkflow to supply tenants with on-demand access to resources such as networks, servers, storage, applications, and services. These cloud resources can be located on BIG-IP devices in a private local network, a public third-party cloud service, or a combination of both.

Tenants have restricted and dedicated access to resources based on their unique tenant role and user account. Cloud space can be expanded, retracted, and reallocated to tenants as needed, providing flexible resource balancing.

Screen resolution requirement

To properly display, the iWorkflow system requires that your screen resolution is set to 1280x1024 or higher.

Browser support

This release supports the following browsers and versions:

  • Microsoft Internet Explorer version 11 and later.
  • Mozilla Firefox version 29.x and later.

606886 iWorkflow Users cannot add or delete static pool members to deployed graphs.  
624154 iWorkflow Sometimes after performing a device reset for both BIG-IP devices in an HA pair, the associated DSC group is removed.

628507 iWorkflow When removing an event handler from the primary iWorkflow in a clustered environment using a PATCH, the peer iWorkflow modules do not remove the same event handler. Issue the same PATCH request to remove the event handler from the peer iWorkflows.
628920 iWorkflow The iWorkflow ssh console will periodically display a message:

011d0004:3: Disk partition var_log has only 5% free Nov 18 11:11:04 iwscale01 emerg alertd[6890]: 01100048:0: Log disk usage still higher than 80% after logrotate and 24 times log deletion

The Online Help and iWorkflow Ops Guide state to verify the hash with an incorrect OpenSSL command.
