September 2018 – Odin 5940 Frodo Upgrade

Odin 5940 FroDo Comware Upgrade

We would like to announce a staged upgrade of the version of Comware running on our HPE 5940 FroDos. This blog entry aims to answer the majority of questions that this work will raise. Please, feel free to contact the Networks team with any further questions at


As part of ongoing maintenance it is essential that we keep our FroDo software up to date. The new version of software being deployed addresses a number of vulnerabilities and bugs. For those interested this upgrade takes us from F2604H04 to R2612H01 and involves more than a dozen devices.

Relevant Bug Fixes

Symptom: After the master of an IRF fabric is rebooted, SNMP obtains an incorrect value for the snmpEngineBoots node.

Condition: This symptom might occur if SNMP is used to obtain the value of the snmpEngineBoots node after the master of an IRF fabric is rebooted.

Effect: This stops management systems from connecting to the SNMP engine on the device. Noticeable and inconvenient because graphs of port throughput are no longer maintained.

Addressed Vulnerabilities

This release addresses the following CVEs





















Information about the detail of these vulnerabilities can be found at


The expected impact is ~5-10 minutes for Option 1 customers during which time the FroDo will reload and external services will not be available. For Option 2 customers the impact is expected to be minimal thanks to the In Service Software Upgrade (ISSU) capability.

We will be carrying out the upgrades between 06:00 and 07:30 to minimise impact.


We plan to upgradeĀ up to 2 FroDos, one option 1, and one option 2, on the each of the following days:

Tuesday 4th September
 frodo-030809 dcdist-br (option 2) - completed
 Notes: Resilience of link to BSP-STORAGE in BRDC not functioning correctly causing interruption and some Left Hand storage entered read-only mode.
        AD DC behind ADFS for Nexus 365 coincidentally failed the night before ~23:00 causing failure of *some* user logins to Outlook. 
        Not caused by Frodo upgrade but we were blamed for it by some before all the details were known.
Wednesday 5th September
 frodo-030811 dcdist-osney (option 2) - completed
 frodo-100907 wellcome-trust - completed
 frodo-100909 orcrb-2 - completed - upgraded 1 day early

Due to an issue encountered on the morning of 5th with two of the upgrades 
we will postpone the remaining ones until further notice pending the result 
of a support call with the vendor.
