This is the release note for the 8.5.4 release and details the issues resolved in 8.5.4.0. This document will be updated with additional information whenever a PTF is released.
Note: This release is a Non-Long Term Support (Non-LTS) release. Non-LTS code levels will not receive regular fix packs. Fixes for issues introduced in a Non-LTS release will be delivered in a subsequent Non-LTS or LTS release. If issues are encountered the only resolution is likely to be upgrade to a later LTS or Non-LTS release.

| Details | Introduced |
|---|---|
|
Upgrade to 8.5.1 and higher is not currently supported on systems with compressed volume copies in Data Reduction Pools, to avoid SVAPAR-105430. On a small proportion of systems, this can cause a node warmstart when specific data patterns are written to compressed volumes. This restriction will be lifted in a future release. |
8.5.1.0 |
|
IBM Spectrum Virtualize for Public Cloud on Amazon Web Services (AWS) supports policy-based replication on c5.18xlarge platform only |
8.5.4.0 |
|
IBM Spectrum Virtualize for Public Cloud on Amazon Web Services (AWS) does not support patch installation using 'applysoftware' or 'installsoftware' command line interface |
8.5.4.0 |
|
IBM Spectrum Virtualize for Public Cloud on Amazon Web Services (AWS) does not support integration with IBM Storage Insights by using Call Home with cloud services |
8.5.4.0 |
| The following restrictions were valid but have now been lifted | |
A release may contain fixes for security issues, fixes for APARs or both. Consult tables below to understand the complete set of fixes included in the release.

| HU02572 | All | HIPER | When controllers running specified code levels with SAS storage are power cycled or rebooted, there is a chance that 56 bytes of data will be incorrectly restored into the cache, leading to undetected data corruption. The system will attempt to flush the cache before an upgrade, so this defect is less likely during an upgrade. (show details) | 8.5.4.0 | Drives |
| SVAPAR-90459 | All | HIPER | Possible undetected data corruption or multiple node warmstarts if a Traditional FlashCopy Clone of a volume is created before adding Volume Group Snapshots to the volume (show details) | 8.5.4.0 | FlashCopy |
| HU02586 | All | Critical | When deleting a safeguarded copy volume which is related to a restore operation and another related volume is offline, the system may warmstart repeatedly (show details) | 8.5.4.0 | Safeguarded Copy & Safeguarded Snapshots |
| SVAPAR-87729 | All | Critical | After a system has logged '3201 : Unable to send to the cloud callhome servers', the system may end up with an inconsistency in the Event Log. This inconsistency can cause a number of symptoms, including node warmstarts (show details) | 8.5.4.0 | Call Home |
| SVAPAR-87846 | All | Critical | Node warmstarts with unusual workload pattern on volumes with Policy-based replication (show details) | 8.5.4.0 | Policy-based Replication |
| SVAPAR-91111 | All | Critical | USB devices connected to an FS5035 node may be formatted on upgrade to 8.5.3 software (show details) | 8.5.4.0 | Encryption |
| HU01782 | All | High Importance | A node warmstart may occur due to a potentially bad SAS hardware component on the system such as a SAS cable, SAS expander or SAS HIC (show details) | 8.5.4.0 | Drives |
| HU02539 | All | High Importance | If an IP address is moved to a different port on a node, the old routing table entries do not get refreshed. Therefore, the IP address maybe inaccessible through the new port (show details) | 8.5.4.0 | |
| HU02558 | FS5000, FS5100, FS5200, FS7200, FS7300, FS9100, FS9200, FS9500, SVC | High Importance | A timing window exists if a node encounters repeated timeouts on I/O compression requests. This can cause two threads to conflict with each other, thereby causing a deadlock condition to occur. (show details) | 8.5.4.0 | Compression |
| HU02589 | FS5200, FS7200, FS9100, FS9200, FS9500 | High Importance | Reducing the expiration date of snapshots can cause volume creation and deletion to stall (show details) | 8.5.4.0 | FlashCopy, Policy-based Replication, Safeguarded Copy & Safeguarded Snapshots |
| SVAPAR-83290 | FS5000 | High Importance | An issue with the Trusted Platform Module (TPM) in FlashSystem 50xx nodes may cause the TPM to become unresponsive. This can happen after a number of weeks of continuous runtime. (show details) | 8.5.4.0 | |
| SVAPAR-84305 | All | High Importance | A node may warmstart when attempting to run 'chsnmpserver -community' command without any additional parameter (show details) | 8.5.4.0 | System Monitoring |
| SVAPAR-85093 | All | High Importance | Systems that are using Policy-Based Replication may experience node warmstarts, if host I/O consists of large write I/Os with a high queue depth (show details) | 8.5.4.0 | Policy-based Replication |
| SVAPAR-85396 | FS5000, FS5100, FS5200, FS7200, FS7300, FS9100, FS9200, FS9500 | High Importance | Replacement Samsung NVME drives may show as unsupported, or they may fail during a firmware upgrade as unsupported, due to a VPD read problem (show details) | 8.5.4.0 | Drives |
| SVAPAR-89780 | All | High Importance | A node may warmstart after running the flashcopy command 'stopfcconsistgrp' due to the flashcopy maps in the consistency group being in an invalid state (show details) | 8.5.4.0 | FlashCopy |
| SVAPAR-89951 | All | High Importance | A single node warmstart might occur when a volume group with a replication policy switches the replication to cycling mode. (show details) | 8.5.4.0 | Policy-based Replication |
| SVAPAR-90395 | FS9500, SVC | High Importance | FS9500 and SV3 might suffer from poor Remote Copy performance due to a lack of internal messaging resources (show details) | 8.5.4.0 | Global Mirror, Global Mirror With Change Volumes, HyperSwap, Metro Mirror |
