Supported host operating systems for high availability

Policy-based high availability supports a reduced set of the operating systems that are supported by IBM Storage Virtualize.

The following operating systems are supported with policy-based high availability when connected by using Fibre Channel SCSI:
  • Red Hat Enterprise Linux, including with KVM (all supported versions).
  • SUSE Linux Enterprise (all supported versions).
  • IBM AIX (version 7.2 and later).
  • Linux on IBM Z (all supported versions and distributions).
  • VMware ESXi (all supported versions).
  • Microsoft Windows Server, including Hyper-V (all supported versions). For more information, see Storage tests on a failover cluster might not discover all shared LUNs.
  • Oracle Solaris (version 11.4 and later).
  • IBM i 7.4 TR11 or later, IBM i 7.5 TR5 or later, IBM i 7.6 or later. Fabric-attached Fibre Channel only.
The following operating systems are supported with policy-based high availability when connected by using iSCSI: Support for the operating systems listed requires using the native multipath driver. Third party multipath solutions are not qualified.

The VMware ESXi 8.0 operating system is supported with policy-based high availability when connected by using NVMe-TCP and NVMe-FC. For details about NVMe-TCP, see VMware ESXi and for details about NVMe-FC, see VMware ESXi installation and configuration for NVMe over Fibre Channel hosts.

For more information about host compatibility, see IBM System Storage Interoperation Center (SSIC).

Hosts that are configured for high availability must have the generic host type. Change the existing hosts with deprecated host types to the generic host type.

Volumes that are configured for high availability cannot be mapped to other IBM Storage Virtualize systems.
