1 Hardware providers and the CAPI Proxy The hardware providers described in this document are used with HP MSA 1040 and HP MSA 2040 storage systems in MIcrosoft Windows Server environments. They are available for download as separate installation files: • A VDS hardware provider for FC and SAS storage systems. • A VDS hardware provider for iSCSI storage systems. • A VSS hardware provider for FC, iSCSI, and SAS storage systems. • A CAPI Proxy that enables in-band management from host-based applications.
interface that enables you to configure your mixed storage environment without having to use individual storage management tools. The MSA 1040/2040 VDS Hardware Provider implements the VDS 1.1 API. After the MSA 1040/2040 VDS Hardware Provider is installed, the Microsoft DiskRaid CLI and Storage Manager for SANs, or VDS client utilities from other third-party vendors, can be used to configure and manage your storage system.
Downloading the providers and the CAPI Proxy 1. Navigate to http://www.hp.com/support/msa2040 or http://www.hp.com/support/msa1040. 2. Click the link to download Drivers, Software & Firmware. 3. Select your storage system. If you have more than one model of MSA 1040 or MSA 2040 storage, you only need to select one to download the hardware providers and CAPI Proxy that apply to all MSA 1040 and MSA 2040 models. 4. Choose a Driver language from the dropdown menu and click Go. 5.
2 Installing and using the MSA 1040/2040 VDS Hardware Provider or HP MSA 1040/2040 iSCSI VDS Provider This section describes how to install the MSA 1040/2040 VDS Hardware Provider. Note that there are two different versions of the provider. One supports iSCSI devices only, and the other supports Fibre Channel and SAS devices. Both can be installed at the same time if you have a mix of iSCSI and non-iSCSI devices.
Supported Microsoft DiskRaid Commands This section contains a list of supported Microsoft DiskRaid commands. • CREATE LUN [SIZE=] [DRIVES=,[,..]][STRIPESIZE=][NOERR] – Creates a new vdisk or creates a volume on an existing vdisk. An existing vdisk is used if it has enough free space to satisfy the request. can be simple, stripe, mirror, raid (NRAID, RAID0, RAID1/10, RAID5, RAID6 and, for Windows Server 2008 only, RAID50). STRIPESIZE is ignored.
Modifying the Microsoft Windows Server 2008 and Windows Server 2012 Default SAN Policy for Newly Discovered Disks When a disk is newly discovered on a Windows Server 2008 or Windows Server 2012 server, it may show up as either online or offline, and may be read-write or read-only. This is influenced by the mapping of the volume. You can modify the SAN policy to change the access level using the DISKPART san policy command in Windows Server 2008 and later.
Troubleshooting This section contains troubleshooting information for the MSA 1040/2040 VDS Hardware Provider. Table 1 Troubleshooting the VDS Hardware Provider Issue Description DiskRaid exits abnormally. Halt and automatically restart the VDS service using this command: net stop vds If the problem persists, use Task Manager to terminate the dllhost.exe process that hosts the VDS provider. If more than one dllhost.
Table 1 Troubleshooting the VDS Hardware Provider (Continued) Issue Description A LUN appears with a capacity of 0KB If a vdisk exists on the array and no volumes are allocated from it, the VDS Hardware Provider will present the vdisk to the VDS subsystem as a LUN with 0 KB of capacity.
3 Installing and using the MSA 1040/2040 VSS Hardware Provider This section describes how to install the MSA 1040/2040 VSS Hardware Provider. NOTE: In a cluster environment the MSA 1040/2040 VSS Hardware Provider cannot be installed unless a Microsoft Distributed Transaction Coordinator (MS DTC) cluster resource is configured. If the host part of a cluster and MSDTC is not running, installation will fail. Refer to http://support.microsoft.com/kb/301600 for instructions on configuring MS DTC. 1.
volume using the CLI (enabling the volume for shadow copies) or create a new master volume using the SMU or CLI. If you try to take a snapshot of an ordinary volume that has not been converted into a master volume first, the VSS Hardware Provider will attempt to convert it to a master volume automatically, after allocating a backing store of approximately 20% of the size of the volume (but not less than 6GB).
The read-only or read-write attribute may also be influenced by the SAN policy of Windows Server 2008 and Windows Server 2012 systems.The SAN policy in place on the server affects the access level for newly discovered disks, but volumes on the disks for VSS shadow copy snapshots are always initially discovered as read-only, regardless of the SAN policy or version of Windows operating system. See LUN 0 Mapping on page 10 for more information.
Troubleshooting This section contains troubleshooting information for the MSA 1040/2040 VSS Hardware Provider. Table 2 Troubleshooting the VSS Hardware Provider Issue Description The VSS Provider cannot create a snapshot. • The maximum number of snapshots allowed by the snapshot license has already been created.
Table 2 Troubleshooting the VSS Hardware Provider (Continued) Issue Description • There are insufficient resources available to create the shadow copy, which can happen if you create and delete shadow copies too quickly. Wait for the controller to make resources available, and then try again. It is taking a long time to create the shadow copy.
