Release Note for systems built with IBM Storage Virtualize


This is the release note for the 8.6.2 release and details the issues resolved in 8.6.2.1. 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

The three site orchestrator is not compatible with the new SSH security level 4.This will be resolved in a future release of the orchestrator.

8.6.2.1

Removing a vVol child pool is currently not supported. Contact IBM Support if you have a requirement to delete a vVol child pool.

8.6.2.0

Due to a known issue, array expansion of DRAID1 arrays is not supported on this code level.

8.6.2.0

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

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

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.

This restriction has been lifted by SVAPAR-106693

8.6.0.0

Upgrading to 8.5.1 or higher was not supported on systems with Data Reduction Pools.

This restriction has been lifted by SVAPAR-105430

8.6.2.0

8.6.1 introduced 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.

8.6.2.0

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

8.6.2.0

Systems with RoCE adapters could not configure an MTU of greater than 1500 with 8.6.0 and 8.6.1 software.

8.6.2.0
