Potential for Data Inconsistency Issues on E-Series Storage Systems
With the controller firmware 11.50.1 and newer version like NetApp controller firmware 11.50.2 an issues are fixed by NetApp, which enforce an immediate update of all E2800 iSCSI Storage Systems (their controllers). In July 2019 BOSCH announced the need to update from all former NetApp controller firmware 08.30.40.00 to newer versions. At that time the Firmware for NetApp E2800 controller recommended was version NetApp Firmware 11.50R1. This is also 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. Eventhough NetApp inbuild functions for BOSCH video optimized recording 24/7 and generic firmware is used at E2800 iSCSI storage systems, BOSCH is evaluating new firmware versions provided by NetApp on a regular bases. The BOSCH submodel ID 356 ensures that the NetApp system is optimized for 24/7 video recording.

Summary of 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.
First announced in 06/2019: The issues are possible on E-Series controllers running 8.30, 8.40, 11.30, 11.40, and 11.50 versions of E-Series SANtricity OS controller software. 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.
No workaround available. Controller Firmware update is needed. HDD Firmware update is not in relation to the descdribed 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.
status 06/2019: controller firmware version minimum 11.50R1
status 10/2019: controller firmware version to be used 11.50.2
