This is the release note for the 8.6.1 release and details the issues resolved in 8.6.1.0. 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.
This document was last updated on 4th April 2024.
Note. Detailed build version numbers are included in the Update Matrices in the Useful Links section.
| Details | Introduced |
|---|---|
|
Systems with ROCE Adapters cannot have MTU greater than 1500 on 8.6.0.0 or later. The workaround is to reduce MTU to 1500.
This restriction has now been lifted in 8.6.1.0. Systems with ROCE Adapters using iSCSI protocol can set MTU to 9000. Systems using NVMe-TCP/RDMA protocol still remain restricted to 1500 MTU value. |
8.6.0.0 |
|
Remote Support Assistance (RSA) cannot be enabled on FS9500 systems with MTM 4983-AH8. Attempting to enable RSA will fail with: CMMVC8292E The command failed because the feature is not supported on this platform. Customers should contact Support for an ifix |
8.6.0.0 |
|
Upgrade to 8.5.1 and higher is not currently supported on systems with 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 later PTF |
8.5.1.0 |
|
VMware Virtual Volumes (vVols) are not supported using IBM Spectrum Connect on 8.6.1 or later. Systems using Spectrum Connect must migrate to use the embedded VASA provider on version 8.6.0 before upgrading to 8.6.1 or later. |
8.6.1.0 |
|
Systems using VMware Virtual Volumes (vVols) may require reconfiguration before updating to 8.6.1 or later. Refer to Updating to Storage Virtualize 8.6.1 or later using VMware Virtual Volumes (vVols) |
8.6.1.0 |
|
All IO groups must be configured with FC target port mode set to 'enabled' before upgrading to 8.6.1.0 or later. Enabling the FC target port mode configures multiple WWPNs per port (using the Fibre Channel NPIV technology), and separates the host traffic from all other traffic on different WWPNs Important: Changing this setting is likely to require changes to zoning, and rescanning LUNs in all applications. The product documentation contains topics called 'Enabling NPIV on an existing system' and 'Enabling NPIV on a new system' which contains details about how to make the changes. |
8.6.1.0 |
|
IBM i is not supported as a host operating system when connected using directly attached Fibre Channel to FlashSystem or SAN Volume Controller systems running 8.6.1.0 or later versions. IBM i is supported as a host operating system when connected to FlashSystem or SAN Volume Controller systems via a Fibre Channel switch |
8.6.1.0 |
|
8.6.1 removes support for the CIM protocol. Applications that connect using the CIM protocol should be upgraded to use a supported interface, such as the REST interface. IBM recommends that any product teams currently using CIM protocol comment on this Idea and IBM will contact you with more details about how to use a supported interface. |
8.6.1.0 |
|
Mapping more than 512 volumes to a single host might fail with CMMVC5876E after upgrading to 8.6.1.0, even if the configuration is supported. Warmstarting any node in the system will resolve the issue, allowing the supported number of volume mappings per host object to be created. |
8.6.1.0 |
|
8.6.1 introduces support for Policy-based High Availability, using two storage systems. Asynchronous Policy-based Replication is not supported in this release and systems requiring this feature should use 8.6.0. |
8.6.1.0 |
|
Systems using 3-site orchestrator cannot upgrade to 8.7.0.0 |
8.6.1.0 |
| The following restrictions were valid but have now been lifted | |
A release may contain fixes for security issues, fixes for APARs or both. Consult both tables below to understand the complete set of fixes included in the release.

8.6.1.0 | GUI, Graphical User Interface | ||||||||
| SVAPAR-100564 | All | Critical | On code level 8.6.0.0, multiple node warmstarts will occur if a user attempts to remove the site ID from a host that has Hyperswap volumes mapped to it.
(show details)
|
8.6.1.0 | HyperSwap | ||||||||
| SVAPAR-98184 | All | Critical | When a Volume Group Snapshot clone is added to a replication policy before the clone is complete, the system may repeatedly warmstart when the Policy-based Replication volume group is changed to independent access
(show details)

8.6.1.0 | FlashCopy, Policy-based Replication | ||||||||
| SVAPAR-98612 | All | Critical | Creating a volume group snapshot with an invalid I/O group value may trigger multiple node warmstarts
(show details)
|
8.6.1.0 | FlashCopy | ||||||||
| SVAPAR-100162 | All | High Importance | Some host vendors such as Windows have recently started to use 'mode select page 7'. IBM Storage does not support this mode. If the storage received this mode level it would cause a warmstart to occur
(show details)
|
8.6.1.0 | Hosts | ||||||||
| SVAPAR-100977 | All | High Importance | When a zone containing NVMe devices is enabled, a node warmstart might occur.
(show details)
|
8.6.1.0 | NVMe | ||||||||
| SVAPAR-102573 | All | High Importance | On systems using Policy-Based Replication and Volume Group Snapshots, some CPU cores may have high utilization due to an issue with the snapshot cleaning algorithm. This can impact performance for replication and host I/O

| SVAPAR-98893 | All | High Importance | If an external storage controller has over-provisioned storage (for example a FlashSystem with an FCM array), the system may incorrectly display usable capacity data for mdisks from that controller. If connectivity to the storage controller is lost, node warmstarts may occur
(show details)
|
8.6.1.0 | Storage Virtualisation | ||||||||
| SVAPAR-99537 | All | High Importance | If a hyperswap volume copy is created in a DRP child pool, and the parent pool has FCM storage, the change volumes will be created as thin-provisioned instead of compressed

(show details)
|
8.6.1.0 | Policy-based Replication | ||||||||
| SVAPAR-96777 | All | Suggested | Policy-based Replication uses journal resources to handle replication. If these resources become exhausted, the volume groups with the highest RPO and most amount of resources should be purged to free up resources for other volume groups. The decision which volume groups to purge is made incorrectly, potentially causing too many volume groups to exceed their target RPO
