On HPE ProLiant Gen10 Plus servers running Windows Server and using RAID 5 volumes managed by Intel Virtual RAID on CPU (VROC) Gen10 Plus software RAID, Intel has published the following technical advisory to make customers aware of an extremely rare potential for data loss exists: Intel Virtual RAID on CPU (Intel VROC): Data Loss Exposure Due to RAID 5 TRIM Support This potential issue occurs on Intel VROC-managed RAID 5 volumes, consisting of at least one Solid State Drive (SSD) that supports TRIM/UNMAP commands by methods other than the use of zeros. IMPORTANT: This issue was identified by Intel during lab testing for corner case issues. Neither Intel nor HPE have received any reports of an occurrence in a production environment. NOTE : This issue is not specific to HPE as it affects other manufacturers using Intel VROC. This issue can only be encountered when all the following conditions have been met on the drive types listed in the Scope section: The volume is a RAID 5. All the RAID member drives are SSDs that support the TRIM command. At least one of the member drives does not TRIM using zeros. A TRIM command to a full stripe has been issued. Following the completion of the TRIM command, a WRITE command is issued with data smaller than a full stripe to this exact stripe. One of the drive members fails prior to the stripe parity being updated, causing the RAID 5 volume to become degraded. The failed drive is replaced, and the RAID 5 rebuild begins. The data loss condition occurs during the rebuild of the affected stripe. For detailed information regarding the root cause of this issue, reference Intel's Technical Advisory linked above.
Any of the following HPE Gen10 Plus servers running Windows Server and using RAID 5 boot or data volumes managed by Intel Virtual RAID on CPU package VROC GUI for Microsoft Windows Server 2016, Windows Server 2019 and Microsoft Windows Server 2022 version 7.7.0.1281 (or earlier): HPE ProLiant DL20 Gen10 Plus server HPE ProLiant DL110 Gen10 Plus Telco server HPE ProLiant MicroServer Gen10 Plus v2 HPE ProLiant DL360 Gen10 Plus server HPE ProLiant DL380 Gen10 Plus server HPE ProLiant ML30 Gen10 Plus server HPE Edgeline e920d Server Blade The following drive models are susceptible to this issue: Drive Type ; SSD Name M.2; SATA Intel Optane Stony Beach M.2; NVMe Samsung PM961 NVMe 2.5"; Intel Optane Cold Stream NVMe 2.5"; Intel Optane AlderStream NVMe 2.5"; Micron* 9200 (3D NAND)
The ability to enable TRIM with RAID5 is disabled for 7.8PV and 8.0PV. As a workaround, immediately disable TRIM support via the following Windows command: -fsutil behavior set DisableDeleteNotify 1 Once disabled, immediately initiate a "Verify and Repair" on all RAID 5 volumes to fix any parity inconsistencies on the volumes. (See the button in the software application, "Intel Virtual RAID on CPU.") This bulletin will be updated if further information becomes available. Revision History Document Version Release Date Details 2 May 8, 2024 In the Resolution section, reference to this issue being resolved in VROC 8.2 was removed, and reference to the bulletin being updated in the future was revised in the Resolution section. 1 September 16, 2022 Original Document Release RECEIVE PROACTIVE UPDATES : Receive support alerts (such as Customer Advisories), as well as updates on drivers, software, firmware, and customer replaceable components, proactively in your e-mail through HPE Support Alerts.
