IBM United States IBM is a registered trademark of International Business Machines Corporation. 299-203 Emulate Error Log Driven Events: The AIX Error Description Notification facility allows customers to define procedures to handle errors that may not be handled by HACMP 4.3.1. HACMP 4.3.1 builds on IBM′s position as a leader in The ability to emulate these error log driven events is high-availability clustering technology with new and added to aid script developers in testing their scripts improved functionality for usability, installability, system without actually having to make the error occur. Errors administration, and additional hardware support. can be inserted into the AIX error device file (/dev/error) through the use of SMIT panels. Support Added for AIX Fast Connect: HACMP 4.3.1 now supports the AIX Fast Connect application as a highly Automated AIX Error Notification Facility: The Automated available resource. AIX Fast Connect enables non-AIX AIX Error Notification facility is enhanced to detect clients, such as Windows 95, Windows 98, Windows NT , automatically what configured resources can be Windows for Work Groups, DOS, and OS/2 , to request associated with an AIX error log event. The default action file and print services from an AIX server. Support for is to log these events in the hacmp.out file. Customers AIX Connections was previously announced in HACMP can develop their own scripts and associate them with Version 4.3. The clverify utility is also enhanced to detect these events. errors in the configuration of AIX Fast Connect with HACMP. Node-by-Node Migration to HACMP/ES: To assist customers who are planning on migrating from the HAS Dynamic Reconfiguration Resource Migration: The or CRM features to the ES or ESCRM features Dynamic Reconfiguration Resource Migration utility is respectively, the node-by-node migration function now accessible through SMIT panels as well as the provides the capability of migrating from HACMP 4.3.1 original command line interface. This utility allows for HAS/CRM to HACMP 4.3.1 ES/ESCRM without having to rotating and cascading resources to be brought online, bring the cluster down. To migrate from a previous offline, or moved. The SMIT panels will make this function release of HACMP HAS or CRM feature to HACMP 4.3.1 easier to use. ES or ESCRM feature, the customer must first migrate to HACMP 4.3.1 HAS or CRM. Swap Adapter: HACMP 4.3.1 is enhanced to allow the swapping of an IP address of an active service or boot C-SPOC Enhancements: C-SPOC is enhanced with the adapter to the address of an available, active standby capability to: adapter that is on the same node and network. The original adapter then becomes an available standby • Make a disk known to all nodes adapter. This removes the restriction that a node must • Create new shared or concurrent volume groups be powered down in order to remove and replace an • Create new file systems on a shared volume group adapter that is hot plugged. This functionality is available • Remove a disk definition through SMIT panels. • Replace a disk in an existing volume group

ATM Hardware Address Takeover: HACMP 4.3.1 now These capabilities are accessible through SMIT panels. supports hardware address takeover on ATM adapters attached to the same switch. This support is already Online Planning Sheets Sample Program: The online available for token ring, Ethernet, and FDDI adapters, and planning sheet sample program provides a convenient alleviates the communications problems that could occur method for the customer to execute the planning process with Adapter swap and IP Address Takeover for ATM for HACMP 4.3.1. At the end of the process, the program adapters. Hardware address takeover is supported for provides the capability of generating a shell script classical IP and ATM LAN emulation. Hardware Address containing the configuration commands that match the Takeover is limited to adapters connected to the same online planning sheets configuration. switch unit. Publications: A new section is added to the HACMP HAView Resource Support: The HAView function is Planning Guide and the HACMP/ES Installation and enhanced to show resource group submaps. The submap Administration Guide that provides guidance to displays a symbol for each node in the cluster that application developers who want their application to work participates in the resource group as well as a symbol for well with HACMP 4.3.1. Also, the HACMP/ES Installation each resource defined in the resource group. The Node and Administration Guide has been split into two volumes. submap is updated to display a symbol for each resource group that the node participates in. Additional Hardware Support: HACMP 4.3.1 now supports the following hardware: Redirect HACMP Log Files: HACMP log file paths no • 7026-H70 longer need to be hard-coded. The pathname of the • 9076-50H HACMP log files is now specified through SMIT panels. • 9076-55H The location of the following files can be specified: • RS/6000 SP Attachment Adapter (#8396) • • clresmgrd.log Advanced SerialRAID Adapter (#6225) • clstrmgr.debug • cluster.mmdd Easy Upgrade and Migration: Node-by-node upgrades • cl_sm.log (version compatibility) are available from HACMP for AIX • cm.log Version 4.
