Opened: Jul 19, 2021

Severity: 4-Minor

Symptoms

It is possible to delete a Pool or Trunk from the configuration while one or more high availability (HA) Groups still reference it. As a result, the configuration of affected high availability (HA) Groups is automatically and silently adjusted (i.e. the deleted object is no longer referenced by any high availability (HA) Group). The lack of warning about this automatic change could lead to confusion.

Impact

The automatic and silent removal of the deleted object from all high availability (HA) Groups may go unnoticed by BIG-IP Administrators, with potential consequences on the failover behavior of the devices.

Conditions

A pool or trunk is deleted from the configuration while still being referenced from a high availability (HA) Group.

Workaround

None

Fix Information

A warning message is logged to /var/log/ltm, and is also presented in tmsh.
