User manual QUANTUM STORNEXT 4.0.1 REPLICATION QUICK REFERENCE GUIDE

[. . . ] The target directories may be on other host machines, or may be on the same host as the source directory. Replication behavior is defined by a Replication/Deduplication Policy. (The other type of StorNext policy is a Storage Manager Policy, which governs how StorNext Storage Manager works). Here are some important facts about StorNext Replication/Deduplication policies. [. . . ] (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. 2 The Configuration > File Systems screen appears. 3 On the Configuration > File System screen, click New. 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. 5 Choose the Replication/Deduplication option. 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.

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. 10 Click Apply to save the new file system. (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. The Configuration > Storage Destinations screen appears. 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. This tab has only one field called Blockpool Host File System. [. . . ] 4 (Optional) To create a new replication schedule, in the Replication Schedules box, click New. Additional fields appear where you can create a replication schedule. Figure 9 Outbound Replication Tab > Replication Schedule 5 Under the heading Select Available Targets, select the target file system on the target server. 6 Create a schedule by making a selection in every column. If you select none of the schedule columns, this creates an unscheduled policy that must be run manually. [. . . ]
