Opened: Sep 04, 2020 Severity: 2-Critical
During boot of a i15xxx system you see the message: Dataplane INOPERABLE - Only 7 HSBs found. Expected 8
When this failure occurs in a system, the system is inoperable.
This issue can occur on any i15xxx device, although some devices exhibit the failure consistently and others never exhibit the issue.
In order to workaround this issue, the system must be updated to install a script that is capable of resetting the hardware device during the HSB load process. If it's not possible to install an EHF with the updated script or a version of BIG-IP with the fix, then it can be installed manually by providing the fw_update_post.init file and replacing it in /etc/init.d/fw_update_post. It is recommended that the existing fw_update_post is backed-up and this is only done in cases where the EHF or a fixed version of BIG-IP cannot be installed.
A 'Dataplane INOPERABLE - Only 7 HSBs found. Expected 8' condition caused by a PCIE linking failure is resolved by an updated HSB load script which correctly resets BIG-IP i15xxx system hardware during boot. Persistent 'Dataplane INOPERABLE' messages, after this fix is installed, indicate an unrelated failure.
