With older NetApp controller firmware it is required to update in order to fix random reboots.
This KB article is relevant for NetApp storage systems running 2020 versions 11.50.2
FW 11.50.2 had to be used for Single Controllers and 11.60.2 for Dual Controllers and then updated to latest version.
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
Newer NetApp controller firmware might be approved and qualified by BOSCH.
In general it is strongly advised to use the the newest NetApp controller versions qualified by BOSCH as well to use newest offered hard drive firmware.
All customers owning a NetApp storage system with valid warranty agreement and registered unit, do have access to the public announcement of NetApp.

The BOSCH sub model ID 356 ensures that the NetApp system is optimized for 24/7 video recording.
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 v11.60.2 was released to solve this issue.
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.
Please take in consideration the following:
NOTE: See also the Release Note of SANtricity OS Controller Software for latest information
There are other models with various HDD capacity (e.g. 8TB hard drives and larger) available.

Important note:
• In general it is strongly recommended to upgrade to latest approved software (e.g. BVMS, VRM), whenever it is possible (keeping mentioned restrictions/limitations in mind), with the listed newest NetApp controller software, NVSRAM file, disk firmware and where needed Expansion Shelf Module (ESM) listed by NetApp. Fixes and comprehensive support services can only offered for the latest approved and secure versions.
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.
Upgrade E-Series SANtricity OS controller software to the latest applicable revision release for each platform as soon as possible.
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.
Additional information is available at NetApp and accessible after user registration.
-----------------------------------------------------------------------------------------------------------------
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. |
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.
Installing the Firmware
-----------------------------------------------------------------------------------------------------------------
The E-Series SANtricity® OS package includes data for simplex controller and duplex controller systems and the firmware file itself.
Attention: Risk of data loss or risk of damage to the storage array — Do not make changes to the storage array while the upgrade is occurring. Maintain power to the storage array.
