    Fix random reboot of NETAPP DSA E2800 (dual controller) by updating its Firmware

    Summary:

     

    FW 11.50.2 must be used for Single Controllers and 11.60.2 for Dual Controllers

     

    Overview:

     

    In Q1 of the year 2020 the BU BT-VS announced that NetApp forces to update all systems E2800 to newer firmware than 11.40.x.

    At that time, it was strongly recommended to go to version 11.50.2 and in February 2020 recommendation was given for 11.50.R2 

    The version 11.50.R2 was forced by NetApp to

    • get proper NetApp support services while valid warranty contract is active
    • and to fix vulnerability aspects.

     

    General Note:

     

    Newer NetApp controller firmware might be approved and qualified by BOSCH

    All customers owning a NetApp storage system with valid warranty agreement and registered unit do have access to the public announcement of NetApp.

    This was announced by NetApp on their support websites (see https://mysupport.netapp.com/).

    Please follow our BOSCH Knowledge Base and monitor for updates at this article for important news. 
    The BOSCH sub model ID 356 ensures that the NetApp system is optimized for 24/7 video recording.

     

    Potential for Data Inconsistency Issues on E-Series Storage Systems

     

    Unfortunately, BOSCH customers contacted the BOSCH technical support where in rare cases customers detected random reboots of DSA E2800 systems running on 11.50.2 or 11.50.R2.

    With the controller firmware 11.50.1 and newer version, issues were fixed by NetApp, which enforce an immediate update of all E2800 iSCSI Storage Systems (their controllers). 

    After this, the new 11.60.2 was released to solve this issue.

    Products that were affected:

     

    Random reboots are possible on NETAPP DSA E2800 controllers running 8.30, 8.40, 11.30, 11.40, and 11.50 versions of E-Series SANtricity OS controller software. 

    • Dual controller E2800 iSCSI storage systems using above mentioned older NetApp Firmware versions
      • We request customers facing a reboot / unexpected iSCSI connection reset to upgrade unit to the firmware v11.60.2 or to get in contact with BOSCH Technical Support. 

    Please take in consideration the following:

    • Simplex/ Single controller E2800 iSCSI storage system According to the BOSCH Product Management and alignment with NetApp: Simplex controller systems E2800 can be operated on NetApp Firmware 11.50.2 only

     

    NOTE: See also the Release Note of SANtricity OS Controller Software 11.60.2 for latest information (status updated on 2021-02-01)

     

    Example product variant:

     

    • DSA-N2C8X4-12AT Dual controller unit 12x4TB High-performance and high-capacity storage system base unit with iSCSI disk arrays, dual controller. DSA E2800, 12 x 4 TB HDD, Order number DSA-N2C8X4-12AT

    There are other models with various HDD capacity (e.g. 8TB hard drives and larger) available.

    Summary of the issue

     

    NetApp® has become aware of issues that could occur when an E-Series controller reboots at certain points during the evacuation of data from a drive that is performed as part of the sequence when a drive is being failed by the controller.

    As a result, there is a small possibility of data inconsistency on controllers running certain versions of E-Series SANtricity® OS controller software.

     

    Issue Description

    The overall probability of these issues occurring is very low, but RAID 1 volumes have a higher probability of encountering the issues than other RAID levels or NetApp Dynamic Disk Pools.

    These issues do not affect traditional RAID volume groups that have no global hot spare drives because drive evacuation does not occur in this configuration.

    For information about fixes in these releases, view the readme notes for each revision release.

     

    Workaround

    No workaround available. Controller Firmware update is needed.
    HDD Firmware update is not in relation to the described issue here, but it is in general recommended to install the latest offered HDD firmware that is recommended by BOSCH and NetApp.
    The same applies for HDD firmware.

     

    Solution: Update the NetApp Controller Firmware

     

    Upgrade E-Series SANtricity OS controller software to the latest applicable revision release for each platform as soon as possible.

    • Dual controller E2800 - firmware v11.60.2
    • Single/ Simplex controller systems E2800 can be operated on NetApp firmware 11.50.2 only

    Or reach out to your local BOSCH technical team and BOSCH BT-SC/ETP-MKP team to ensure that the relevant NetApp Firmware has been approved to be usable for 24/7 video recording and replay use case.

     

    Where to get the Controller Firmware

     

    • All customers with a full NetApp NOW support account and valid warranty on their system can download the controller firmware by using the own NetApp user account. The version offered at the NetApp NOW platform should be certified and allowed by BOSCH for video use cases. 

    • In case the download option is not offered to one of our customers, we kindly ask to make sure that the unit is registered on the company and that the NetApp NOW account belongs to the company that has registered the unit. In all other cases, please ask for help to the BOSCH Support organization or local Bosch Technical Support. Tech Support able to provide the firmware in some emergency situations is the Technical Support Solution Group.
    • A NetApp SANtricity firmware / controller firmware package for E2800 model can be downloaded from the NetApp NOW website.

    General Instructions for Downloading E-Series Disk Firmware:

     

    NetApp uses multiple suppliers for physical disk drives, and each has its own disk drive firmware. Disk firmware updates are published on an as-needed basis; therefore, it is possible that although newer disk firmware files are available, they are not applicable to any of the physical drives in your system.

    Step

    Action

    1

    Verify the Product ID and Firmware level of the disk drives using the Storage Array Profile from within SANtricity ES Storage Manager.

    2

    Determine if the Firmware level on the download site is higher than the current firmware on your drive. Proceed to step 3 if there is a later version. If your firmware is the current version there is no need to download the file.

    3

    Extract the .zip or .gz file for the Drive Identifier matching the Product ID to a temporary location on the system where SANtricity ES Storage Manager is installed.

     

    Instructions for Installing E-Series Disk Firmware

     

    Before you begin
    Downloading firmware incorrectly could result in damage to the drives or loss of data. If you have any questions contact Technical Support before proceeding.

    • Verify that you have downloaded the correct dlp package for the Product ID of the drive.
    • Verify that the storage array is in an Optimal State
    • Verify that no configuration changes are running on the storage array
    • Stop all I/O to the storage array before the download.
    • Do not make any configuration changes to the storage array while downloading the firmware.

     

    Installing the Firmware

    • From the Array Management Window of SANtricity ES Storage Manager, select Upgrade > Drive/ATA Translator Firmware
    • Follow the instructions for selecting and downloading the firmware
