Opened: Mar 31, 2025 Severity: 3-Major
GTM pool are not in sync, running list gtm pool does not show the same pool members.
GTM devices are out of sync.
This happens after deleting an ltm virtual that is listed in a gtm server configured with virtual-server-discovery enabled and in which a GTM Pool has min-members-up-value configured. If the deletion of the ltm virtual server (example: tmsh delete ltm virtual vs1) brings the number of virtual server below the configured value with min-members-up-value, then a mismatch occurs with the other GTM on other BIG-IP.
Avoid the deletion of ltm virtual if this would bring the number of members below the configured min-members-up-value.
