IBM Storage Virtualize announced a new version of the product (9.1.1) with support for FlashSystem grid partition migration with iSCSI hosts.
This blog illustrates the process of FlashSystem grid Partition Migration in environments that use both Fibre Channel (FC) and iSCSI hosts. It highlights the similarities and differences in how host paths are managed during migration, ensuring non-disruptive data access.
Aspect

Fibre Channel (FC) and iSCSI
FlashSystem grid Requirement
Source and target systems must be in the same FlashSystem grid with active partnerships or in active zoning/in candidate for partnership creation (as it will get created as part of migration)
Connectivity
FC zoning for SAN; IP connectivity for iSCSI
Host Configuration
Multipath software installed and configured on all hosts
Snapshot Handling
Snapshot policies can be preserved or recreated on target system
Host Path Updates
Automatic for ESXi and multipath-enabled hosts; manual rescan may be needed
Downtime
Non-disruptive (I/O continues during migration)
Limitations
Requires compatible firmware versions; some OS may need manual intervention
