User manual QUANTUM STORNEXT 4.0.1 REPLICATION QUICK REFERENCE GUIDE

[. . . ] For example, a policy in a file system called /stornext/sn1 can be used only to replicate directories in that file system. A separate policy would be needed to replicate directories from file system /stornext/ sn2. · If a replication/deduplication policy will be used in any file system on a machine, you must configure a blockpool for that machine. The blockpool for a machine contains data (called blocklets) if the Deduplication feature is used, but the blockpool must be configured for replication use even if you do not use deduplication. [. . . ] (For more information, see the Configuration Wizard chapter in the StorNext User's Guide. These instructions assume you are using the StorNext Configuration Wizard and have already completed its first three steps: Welcome, Licenses, and Name Servers. 2 Replication Process Overview StorNext 4. 0. 1 Step 1: Create Source and Target File Systems After you complete the first three Configuration Wizard steps, the first replication step is to create file systems: the blockpool file system(s), and the source and target file systems you plan to use. Note: Although StorNext supports replicating from multiple source hosts and file systems to multiple target hosts and file systems, for simplicity this procedure describes how to replicate between one source and one target file system on the same host. 1 If you have not already done so, launch the StorNext Configuration Wizard and proceed through Welcome, License and Name Servers steps to the File System step. The Configuration > File Systems > New Screen appears. Figure 1 Configuration > File Systems > New Screen 4 At the File System Name field enter the name of a file system to be used as a replication source. A default mount-point path automatically appears but you can change this mount point if you wish. A warning message alerts you that "A blockpool has not been created. " Disregard this message for now because you will create the blockpool file system in Step 2: Setting up the Blockpool. 6 Make sure the Generate option is selected, and then click Continue to proceed. Configuring Replication 3 StorNext 4. 0. 1 Replication Quick Reference Figure 2 Configuration > File System > New Screen 2 7 Select a set of LUNs for the file system, and then click Assign. 8 Click Continue. Figure 3 Configuration > File System > New Screen 3 9 If desired, click the arrows beside the Advanced Parameters and Stripe Group/Disk Management headings to view information. (For more information about creating file systems, see the Configuration Wizard chapter in the StorNext User's Guide. ) 4 Configuring Replication StorNext 4. 0. 1 Creating a Target File System and Blockpool File System 1 Repeat the process (steps 1 - 8) and create the file system you intend to use as a target for replication on this same server. 2 Configure another file system for the Blockpool that has neither Data Migration nor Replication/Deduplication enabled. Step 2: Setting up the Blockpool In this step you will set up the blockpool on the blockpool file system you just created in the previous step. 1 Choose the StorNext Configuration Wizard's Storage Destinations task. There are four tabs on this screen: Library, Storage Disk, Replication Targets, and Deduplication. When configuring replication we are concerned with the Replication Targets and Deduplication tabs. (The deduplication infrastructure is used to handle the transfer of file data for the replication feature, so it must be configured even when the deduplication feature is not used. ) 2 Click the Deduplication tab. The Configuration > Storage Destinations > Deduplication Screen appears. Figure 4 Configuration > Storage Destinations > Deduplication Screen (Blockpool) 3 Click the Deduplication tab. At this field select from the dropdown list the file system to use for the blockpool. (This is the file system you created in the previous step. ) Note: Once applied, the blockpool location cannot be moved to another file system. Be certain of the blockpool location before you continue. Configuring Replication 5 StorNext 4. 0. 1 Replication Quick Reference 4 After you select the blockpool file system, click Apply. This job typically finishes in a few minutes depending on the size parameter of your deduplication license. Step 3: Creating Replication Targets In this step you will specify the actual targets to which you want replicated data sent. [. . . ] · Click Configure. Choose the Source File System 1 After you click Configure, the screen for configuring a replication/deduplication storage policy appears. 2 Click the Source Directories tab. Configuring Replication 7 StorNext 4. 0. 1 Replication Quick Reference Figure 7 Configuration > Storage Policies > New / Source Directories Screen 3 At the Directory field, enter the name of a directory you want to create for the replication source directory. 4 Click Create Directory, and then click Add to add the new directory to the policy. Enter OutBound Replication Information 1 Click the Outbound Replication tab. Figure 8 Storage Policies > New > Outbound Replication Tab 2 At the Outbound Replication field, enable outbound replication (going out from the source) by clicking the area to the right of the field so that On is displayed. 8 Configuring Replication StorNext 4. 0. 1 3 Click Inherit to the right of the Copies to Keep on Target field, and then select 1 from the dropdown list. 4 (Optional) To create a new replication schedule, in the Replication Schedules box, click New.
