HP Matrix Operating Environment 7.1 Release Notes
Managed node installation
Limitations
Multipath I/O and Emulex FC HBA or Emulex FlexFabric Converged Network Adapter is not
supported on Windows Server 2008 and Windows Server 2008 R2
Using multipath I/O during OS installation is not supported with an Emulex FC HBA or an Emulex
FlexFabric Converged Network Adapter on any Matrix-supported server on Windows Server 2008
and Windows Server 2008 R2.
The following suggested actions enable you to install the OS single-path and then modify the
storage definitions to create multiple-path access to the boot volume. After a successful OS
installation, these instructions will define an additional physical path to the boot volume by:
• Modifying the storage definition to add an additional server HBA definition (port)
• Modifying the boot volume definition to add a second physical ‘path’ to its definition.
Suggested action 1
If you are creating a template using Matrix OE infrastructure orchestration designer:
1. Do not select Redundant SAN paths to disk when configuring storage.
With this box unchecked, infrastructure orchestration will select a storage pool entry with a
single path, or will create a single-path storage pool entry during storage auto-generation.
If you are using SPM with pre-existing volumes or with on-demand provisioning, SPM will fulfill
the storage request with a volume presented over a single path and will only zone one path.
2. After OS provisioning, modify the storage pool entry to add on additional path. SPM will
make the appropriate adjustments.
Suggested action 2
If you are defining a storage pool entry in Matrix OE logical server management:
1. Define the storage pool entry, adding multiple ports, and marking all non-boot disks as
redundant. Keep the boot volume as a single path.
2. Assign the storage pool entry to a logical server.
3. Activate the logical server.
4. Provision the OS, and install the multipath IO drivers as appropriate.
5. Deactivate the logical server.
6. Modify the storage pool entry to make the boot volume redundant.
7. Reactivate the logical server.
