HA and Distributed LAN Clients On a StorNext HA system using the StorNext Distributed LAN Client/Server (DLC) feature: When configuring DLC Server on the MDCs of an HA cluster, it must be configured byhand on each MDC. Service will be lost when an HA Reset occurs, so DLC clients should be configured to access the DLC file systems through both MDCs. This practice allows for the best and highest availability of the DLC capability. Ideally, each node in the HA pair should have the same number of NICs and be on the same networks. The dpserver configuration should be done before converting an MDC pair into an HA pair. 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. 0 Follow these steps to configure HA: 1 Choose HA > Convert from the Tools menu. The Tools > HA screen appears. Figure 1 Tools > HA Screen 2 At the Shared File System field, select the shared file system you want to convert to HA. 3 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. 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. 7 Click Convert to convert the secondary system. 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 certain types of configuration changes through the GUI. Managing HA 3 StorNext 4. 0 HA Quick Reference Follow these steps to lock the HA cluster and enter Config mode, and subsequently to exit Config mode: 1 Choose HA > Manage from the Tools menu.
