The "IBM DS4000 Storage Manager version 9.12 Linux support for pSeries" CD-ROM contains the documentation and files necessary for installing the IBM DS4000 Storage Manager Version 9.12 Client host software in non-LoP servers that is required to setup and manage the DS4000 storage subsystem that are connected to Linux on pSeries(LoP) servers. In addition, for the Linux on pSeries(LoP) servers with Redhat RHEL3-u4 installed, there are IBM DS4000 Storage Manager Version 9 host software packages in the LoP directory of the "Linux support for pSeries" CD-ROM that can be installed in these RHEL3-u4 LoP servers for managing the DS4000 storage subsystems. (see Note below for Linux on Power installations). These host software packages are also available in the IBM TotalStorage™ Disk Storage Systems Technical Support web site. Supported pSeries configurations and setup information can be found in the following DS4000 storage server document - IBM DS4000 Storage Manager Version 9 Installation and Support Guide for AIX, HP-UX, Solaris and Linux on POWER - which is located in the \Docs directory on this CD. Also, refer to the http://www.ibm.com/eserver/pSeries/linux IBM web site for the latest Linux for pSeries information and document updates. Please read the FAStT EXP100 Storage Expansion Unit Release Notes before using Storage Manager version 9.1 on FAStT storage server connecting to EXP100 enclosures. IMPORTANT: This release of IBM FAStT Storage Manager host software for LoP servers supports all FAStT storage subsystems with general released firmware versions from 5.3x.xx.xx up to 06.12.xx.xx. For the latest DS4000 readme files, publications, and released code, refer to the http://www.ibm.com/servers/storage/support/disk IBM TotalStorage™ Disk Storage Systems Technical Support web site. Refer to the IBM DS4000 Support Web Site for latest DS4000 controller firmware and NVSRAM files for IBM machine types 1722, 1724, 1742, 3542 and 3552. The following table shows the first four digits of the latest controller firmware versions that are currently available for various models of the DS4000 storage subsystems, which are supported for having logical drives (LUNs) mapped to LoP servers. --------------------------------------------------- | | Controller firmware version | |------------------|--------------------------------| | DS4000 | | | Storage Server | | | Model | | |------------------|--------------------------------| | DS4500 (1742) | 06.12.xx.xx | |------------------|--------------------------------| | DS4400 (1742) | 06.12.xx.xx | |------------------|--------------------------------| | DS4300 Turbo | 06.12.xx.xx | | Option (1722) | | |------------------|--------------------------------| | DS4300 | 06.12.xx.xx | | Standard Option | | | (1722) | | |------------------|--------------------------------| | DS4300 Single | 05.34.xx.xx | | Controller Opt. | (for DS4300 SCU | | (1722) | only) | |------------------|--------------------------------| | DS4100 (1724) | 06.12.xx.xx | | | | |------------------|--------------------------------| | DS4100 Single | 05.42.xx.xx | | Controller Opt. | (for DS4100 SCU | | (1724) | only) | |------------------|--------------------------------| | FAStT500 (3552) | 05.30.xx.xx | |------------------|--------------------------------| | FAStT200 (3542) | 05.30.xx.xx | --------------------------------------------------- New features that are introduced with the controller firmware version 06.12.xx.xx or later will not be available for any FAStT storage server controllers without the controller firmware version 06.12.xx.xx or later installed. ======================================================================= 1.2 Limitations ---------------- 1. The IBM DS4000 Storage Manager version 9.12 host software packages for Linux on Power are only available on pSeries hosts running Redhat RHEL3 update 4 at this time. They are not available for installation on LoP pSeries hosts running the SLES 8 and SLES 9 Linux operating systems. The Storage Manager version 9.12 Client program for non-LoP operating systems like Microsoft Windows, AIX and non-LoP Linux must be installed in a non-LoP server for out-of- band management configuration of the DS4000 storage subsystems that are connected to LoP servers running SLES 8 and SLES 9 Linux OSes. 2. For the IBM DS4000 Storage Manager version 9.12 Client limitations, refer to the appropriate operating system readme files. These readme files can be found in the operating system (LoP, WIN32, WS03_32bit, WS03_64bit, Linux, Linux_IA64 or AIX) directories on this CD. For the latest DS4000 readme files, publications, and released code, refer to the IBM TotalStorage™ Disk Storage Systems Technical Support web site. http://www.ibm.com/servers/storage/support/disk 3. Refer to the "IBM DS4000 Storage Manager Version 9 Installation and Support Guide for AIX, HP-UX, Solaris and Linux on POWER", version 01, publication located on the http://www.ibm.com/eserver/pSeries/linux IBM web site for the latest Linux for pSeries limitations and document updates. 4. The "modprobe" command is not supported with this release on RHEL3-u4 when the Linux RDAC driver is installed. Use "insmod" to remove and recover the device driver stack. On pSeries servers with more then 4 processors, using the modprobe command may result in a hung server. 5. The Storage Manager Linux RDAC driver does not have the functionality to detect when a LUN is removed from the server. This includes FLASH Copy LUN's. Error messages are reported to the /var/log/messages file until missing LUN is recognized. The work around at this time is to reboot the pSeries server. 6. There is no support for multipath at this time with the SLES 9 kernel (2.6.5-9x) ======================================================================= 1.3 Enhancements ----------------- 1. LoP server with Redhat RHEL3 update 4 (RHEL3-u4) now supports Linux RDAC capabilities using the IBM DS4000 Storage Manager Linux RDAC driver version 9.00.A5.06. This is a different redundant failover/failback driver than the Emulex rdac/device driver that is currently supported for LoP servers running SLES 8. The IBM DS4000 Storage Manage RDAC driver version 9.00.A5.06 do not support only LoP servers running RHEL3-u4. 2. The following DS4000 Storage Manager host software packages - SMclient, SMutils, and SMagent packages are now supported on this LoP servers with Redhat RHEL3 update 4. ======================================================================= 1.4 Prerequisites ------------------ For the IBM DS4000 Storage Manager version 9.12 Client prerequisites, refer to the appropriate operating system readme files. These readme files can be found in the operating system (WIN32, WS03_32bit, WS03_64bit, Linux, Linux_IA64 or AIX) directories on this CD.
