User manual QUANTUM STORNEXT 4.1 HA QUICK REFERENCE GUIDE REV A

[. . . ] 4 User's Guide. HA Overview The StorNext HA feature is a special StorNext configuration with improved availability and reliability. The configuration consists of two similar servers, shared disks and possibly tape libraries. One of the servers is dedicated as the initial primary server and the other the initial secondary (standby) server. [. . . ] Ideally, each node in the HA pair should have the same number of NICs and be on the same networks. Converting to HA Converting to HA consists of selecting your dedicated unmanaged StorNext file system for use as the controlling shared file system, and then instructing StorNext to convert the node to HA. Note: The Convert menu option will be unavailable (grayed out) on the Tools menu if you do not have a secondary system. If you have not already done so, specify a secondary system by using the Name Servers function. For more information, see the Configuration Wizard chapter in the StorNext User's Guide. 2 Pre-Conversion Steps StorNext 4. 1 Follow these steps to configure HA: 1 Choose High Availability > Convert from the Tools menu.

Figure 1 Tools > HA Screen 2 At the MDC Address field, select one IP address to be placed in the ha_peer file for use in administrative operations between the MDCs in the HA Cluster. 3 At the Shared File System field, select the shared file system you want to convert to HA. 4 If your HA cluster also runs the blockpool, select Enable and then enter the virtual IP address and virtual netmask. (Ask your network administrator for the vIP address and netmask. ) 5 Click Convert to convert the primary node to HA. 6 Enter the IP address of the secondary system on the same LAN, and then click Scan. If you do not already have licenses for the secondary system in the license file, you will be required to switch to the license page to import them before continuing. Note: Until you have performed the scan, you cannot import the license file for the secondary system using StorNext's import function. After you have performed the scan you can import licenses for the secondary. Following the conversion to HA, the license file will contain both primary and secondary licenses and will be present on both servers. 7 Click Convert to convert the secondary system. Converting to HA 3 StorNext 4. 1 HA Quick Reference Managing HA The StorNext Manage HA screen is used to monitor the current statuses of your primary and secondary servers. The screen includes Enter Config Mode and Exit Config Mode buttons to place the HA Cluster in a state that allows the Primary MDC to restart CVFS and individual FSMs without incurring an HA Reset, failover of any file systems, or transfer of Primary status to the peer MDC. This is required for making configuration changes to the HaShared file system through the GUI.
