IBM Tape Library SMI-S Agent 1.2.1 Release Notes ------------------------------------------------ Introduction ------------ Release 1.2.1 of the IBM Tape Library SMI-S Agent has been certified under the Storage Network Industry Association's (SNIA) Storage Management Initiative Specification (SMI-S) and provides a SMI-S 1.1.0 CIM interface for managing IBM TotalStorage 3584 Tape Libraries. Please see http://www.snia.org/ctp/conformingproviders/ibm for details of the SMI-S conformance. The enhancements and SMI-S conformance provided by this release include defect fixes for the IBM TotalStorage 3584 Tape Library device. Existing support for the other IBM TotalStorage tape libraries including 3581, 3582, 3583, and 3494 remains unchanged. The IBM Tape Library SMI-S Agent 1.2.1 uses a Pegasus 2.4 CIMOM and DMTF CIM Schema version 2.10.1. Please check the following IBM Tape Library SMI-S Agent support website to download the latest electronic version. http://www.ibm.com/servers/storage/support/software/smisagent/downloading.html Install/Upgrade --------------- For complete installation and upgrade instructions, refer to the "SMI-S Agent for Tape on Linux Systems Installation guide" located in SMI-S/doc directory. Refer to the notes section below for additional installation and configuration instructions. Upgrade is possible from either release 1.1.0, 1.1.1, or 1.2.0 to release 1.2.1. The installation utility will automatically detect the earlier installed version and upgrade to Release 1.2.1 after confirmation. Minimum Requirements -------------------- In addition to the prerequisites contained in the Installation Guide, the following tape library firmware level is required for the fixes contained in the SMI-S agent release to work correctly. IBM 3584 Tape Library firmware level: 5550 or later It is recommended that you use the latest IBM Tape Drive firmware level supported by the library. The IBM Tape Library and Tape Drive firmware can be found online at: http://www.ibm.com/servers/storage/support/lto/3584/downloading.html Defect Fixes in release 1.2.1 ----------------------------- defect Description ------ --------------------------------------------- 19574.ta2 3584 MIB changes for severity field impacts SMIS agent The 3584 Tape Libraty firmware Tape Alert values did not match the MIB. The agent mapping between Trap severity and indication PerceivedSeverity has been updated to match the corrected MIB. 19481 All drives/changers not shown for library Due to an error in FCPort table scanning, one FCPort could be left out of an enumeration of FCPort instances. The scan error has been fixed. Open Issues in Release 1.2.1 ---------------------------- Defect Description ------ ------------ 16830 Property list parameter is case sensitive The case semantics in general for CIM objects is case-insensitive with case-preserved as defined in the mof. But the provider does a case-sensitive compare to determine the filter properties to populate the values. As a result, a value of null is returned for such unmatched properties. Use the correct case for the property names as defined in the mof in any supplied property filter list to avoid this problem. 17973 SystemName property does not match the library's name property The SystemName property value for CIM objects that have the IBMTSSML3584_TapeLibrary as the top-level object does not match the IBMTSSML3584_TapeLibrary Name property value. One example of such object class is IBMTSSML3584_TapeDrive. Regardless of this difference, CIM associator and reference operations work correctly, given an instance of the objects as returned by the agent. Do not directly use the SystemName property value embedded in a reference to such dependent objects. 18477 Alert indications from non-registered devices may be delivered Alert indications are generated based on receiving SNMP traps from a tape library device. Currently, the agent does not check if a received SNMP trap is from a tape library device managed by the agent. As a result, if the IP of the host running the SMI-S agent is configured as a trap destination in a tape library device and that library is NOT configured in the agent, the agent will not filter these traps out and will deliver corresponding alert indications to all registered subscribers. Make sure that the agent host IP address is not in the SNMP destination list of any of tape libraries not managed by the agent. Consult the library operator manual for instructions on modifying SNMP trap destinations. 18684 Additional profile indications not delivered Only alert indications are delivered to registered CIM indication subscribers. Instance life cycle indications including instance modifications are not currently generated. 18836 Configuration with alternate HTTP and HTTPS ports not supported The default ports 5988 for HTTP and 5989 for HTTPS are the only supported ports. In addition, the HTTP service on port 5988 must be enabled for device configuration and indication delivery. 18851 Enabling Pegasus user authentication not supported Although Pegasus 2.4 user authentication can be enabled, local CIM applications including adding a tape library device, stopping the agent, and delivering indications will not work. 19058 SMI-S agent may not respond to CIM requests after fresh install The SMI-S agent service as started by installer does not have the proper environment settings. Restart the agent after a fresh install using the following commands as root user. /etc/init.d/tapecimom stop /etc/init.d/tapecimom start Notes for Release 1.2.1 ----------------------- The IBM 3584 Tape Library must be configured to allow SNMP requests by enabling the "SNMP Requests Setting" in the Tape Library Specialist. In addition, the IBM 3584 Tape Library needs to be configured to deliver SNMP V2C traps to the IP address of the SMI-S Agent host.
