| + | |
| − | The next release of XenServer & Citrix Essentials for Hyper-V will include built-in support for QuantaStor but until then you can add support to your XenServer 5.5/5.6 instances by following a few steps. | + | |
| − | ==== Step 1: Installing the QuantaStor StorageLink Adapter ====
| + | |
| − | After you have StorageLink installed and licensed you can add the QuantaStor adapter by downloading and running the StorageLink adapter installer available from our [http://www.osnexus.com/downloads/ downloads] page. Before installing the QuantaStor StorageLink adapter you'll need to first stop the StorageLink service by typing this command at an Administrator command prompt or by stopping the StorageLink service using the Windows Services panel.
| + | |
| − | <pre>
| + | |
| − | c:\> net stop storagelink
| + | |
| − | </pre>
| + | |
| | | | |
| − | After the service is stopped you can now install the QuantStor StorageLink Adapter using the installer executable:
| + | == User Guide Topics == |
| − | [http://www.osnexus.com/downloads/osn_quantastor_client.exe osn_quantastor_client.exe]
| + | |
| | | | |
| − | Additionally, you'll need to add this block of XML to the end of the StorageLink configuration file located here:
| + | [[iSCSI Initiator Setup]] |
| − | C:\Program Files\Citrix\StorageLink\Server\scsi_device_id_config.xml
| + | |
| − | <pre>
| + | |
| − | <ScsiDeviceIDProcessor>
| + | |
| − | <InquiryMatch>
| + | |
| − | <Vendor>OSNEXUS</Vendor>
| + | |
| − | <Product>QUANTASTOR</Product>
| + | |
| − | </InquiryMatch>
| + | |
| − | <VendorID value="OSNEXUS" />
| + | |
| − | <ProductID value="QUANTASTOR" />
| + | |
| − | <EnclosureID page="128" offset="4" length="8" />
| + | |
| − | <DeviceID page="128" offset="12" length="8" />
| + | |
| − | </ScsiDeviceIDProcessor>
| + | |
| − | </pre>
| + | |
| | | | |
| − | Also, at the top of this file you'll find a version number that looks like this:
| + | [[Multipath IO Configuration]] |
| − | <pre>
| + | |
| − | <version>2.0.0.4</version>
| + | |
| − | </pre>
| + | |
| − | You'll want to increase that version number so that it is something like this:
| + | |
| − | <pre>
| + | |
| − | <version>2.0.0.5</version>
| + | |
| − | </pre>
| + | |
| − | That tells StorageLink that it needs to upgrade your XenServer systems with these new device identification rules.
| + | |
| | | | |
| − | Now you're ready to restart the Citrix StorageLink service:
| + | [[NFS Configuration]] |
| − | <pre>
| + | |
| − | c:\> net start storagelink
| + | |
| − | </pre>
| + | |
| − | ==== Step 2: Installing the XenServer multipath configuration settings ====
| + | |
| − | XenServer utilizes the Linux device-mapper multipath driver (dmmp) to enable support for hardware multi-pathing. The dmmp driver has a configuration file called multipath.conf that contains the multipath mode and failover rules for each vendor. There are some special rules that need to be added to that file for QuantaStor as well. To that end, you'll need to edit the /etc/multipath-enabled.conf file located on each of your XenServer dom0 nodes. In that file, just find the last '''device { }''' section and add this additional one for QuantaStor:
| + | |
| − | <pre>
| + | |
| − | device {
| + | |
| − | vendor "OSNEXUS"
| + | |
| − | product "QUANTASTOR"
| + | |
| − | getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
| + | |
| − | path_checker readsector0
| + | |
| − | path_grouping_policy multibus
| + | |
| − | failback immediate
| + | |
| − | }
| + | |
| − | </pre>
| + | |
| | | | |
| − | Again, apologies for the inconvenience here. We're working closely with Citrix to get this integrated so that everything is pre-installed with their next product release.
