The readme files contain information that may not be included in the IBM T4500 documentation. The readme files take precedence over the documentation. Therefore, any information in this file that conflicts with information in the documentation will supercede the TS4500 Tape Library Operator Guide. The IBM TS4500 Tape Library is responsible for providing basic and advanced tape functionality for backup/restore and archive environments. For more details on functionality and other operation procedures, consult your copy of the TS4500 Tape Library Info Center. A softcopy is available for viewing at the following link: http://www-01.ibm.com/support/knowledgecenter/STQRQ9/com.ibm.storage.ts4500.doc/ts4500_ichome.html In order to provide maximum performance and reliability, it is recommended that the latest version of microcode is installed on your IBM tape libraries and tape devices. These firmware updates are intended to, among other things, increase overall reliability, improve tape handling, further reduce any possibility of data errors, and provide continued enhancements to diagnostic capabilities. CODE LEVEL RECOMMENDATIONS: ================================================================================================= | | Firmware Level | Prereqs | ------------------------------------------------------------------------------------------------- | Recommended Firmware Level | 1.1.0.2 | NA | ------------------------------------------------------------------------------------------------- Notes: 1. 1.1.0.2 level of code is uspported on IMC system level 7.3.15 2. The MIB files are not installed on the library. They are installed on the customer SNMP client. 3. 1.1.0.2 level of code supports up to 4 frames installed, single media, no Shuttle span attachment. SUPPORTED OPERATING SYSTEMS: This tape library works with the following operating systems: AIX, pSeries, xSeries, zSeries, Oracle Solaris and Windows. For details on supported tape attachment please refer to the System Storage Interoperation Center website. http://www.ibm.com/systems/support/storage/config/ssic/ TROUBLESHOOTING: IBM Tape Diagnostic Tool (ITDT) provides the customer with functionality to perform maintenance tasks and run diagnostic tasks to determine tape device issues. This is available to download with the device driver. Support: Support for the following ITDT version: * ITDT-SE v7.1.0 build 065 * ITDT-GE v7.1.0 build 065 * CLI v1.0 Support for the Following MIB Files: *Go to Fix Central under the TS4500 product and get the latest MIB file Known Issues and Limitations: - Windows/Emulex: No support for direct attachment to tape storage devices with the Emulex-based 8Gb host bus adapters. Link failures when direct connected will cause the host to lose communication with the tape storage device, and a host reboot will be needed to regain communication between the host bus adapter and the device. - Windows/Emulex: When HBA topology setting is set to auto-topology in an N-port/F-port environment, the HBA may run out of B2B credits (due to link failures), and then will abend job due to a known issue during the link reset recovery procedure. To avoid this situation, it is recommended that the HBA topology setting is set to N-port/Fport. - Brocade: Brocade HBAs, and their IBM version, do NOT support L-port topology. Direct attach configurations to our Tape Storage products is therefore NOT supported with these cards. - Brocade: Brocade HBA driver on Linux has to be installed manually by user, as it is not native on the operating system - AIX: NPIV attachment support via the FC 5729, 5735 and 5273 Fibre Channel HBA (requires VIOS 2.2 or later). - CPF/DPF: Control Path and Data Path Failover is not supported when running devices connected to a single host server with HBAs that use different HBA drivers. - Solaris 11: ITDT, scripting command 'append', which opens the device in the append mode, can fail with the IBM device driver. Either use any other opening mode and/or use the generic device in case it fails. - Windows: When performing power on reset (power cable pulls) to the 3592-E06, 3592-E07, Ultrium TD6 LTO and Ultrium TD5 LTO tape drives, after a successful Control Path Failover, old changer path could not be reconfigured automatically by Windows Device manager, the medium changer library will need to be reconfigured manually. - Windows: ITDT Report 30, running read/write test with ITDT intermittent failures are appearing due to the toggling of Logical Block Protection, this is occurring with Jag4, LTO6 and LTO5. - Solaris: The server reboots when running the ITDT command "VERLBP" on TS1140 EH7 tape drives with IBM device driver on Sparc/x64 severs with Solaris 10 and 11.1. - CPF/Linux: The double failure scenario in a Control Path Failover test scenario fails when running IO on Linux OSs, operates as expected with no IO running. - Changers/SMCs are lost on the server/host when a reset/reboot is performed to the drive. - Failed to configure speed setting on tape drives LTO6, LTO5 & Jag4 with CLI (Command Line Interface) tool.
