ESS Please refer to SDD support matrix to determine the supported SDD levels for above storage subsystem. 1.2 How to get help Go to the following Web site for SDD technical support and for the most current SDD documentation and support information: http://www.ibm.com/servers/storage/support/software/sdd.html Go to the following Web site for the IBM ESS Open Systems support: http://www.storage.ibm.com/hardsoft/products/ess/supserver.htm Go to the following Web site for IBM TotalStorage DS8000 support: http://www.ibm.com/servers/storage/disk/ds8000/index.html Go to the following Web site for IBM TotalStorage DS6000 support: http://www.ibm.com/servers/storage/disk/ds6000/index.html Go to the following Web site for IBM TotalStorage DS4000 support: http://www.ibm.com/servers/storage/disk/ds4000/index.html Go to the following Web site for IBM TotalStorage DS5000 support: http://www.ibm.com/servers/storage/disk/ds5000/index.html Go to the following Web site for IBM TotalStorage SAN Volume Controller support: http://www.ibm.com/servers/storage/support/virtual/2145.html Call one of the following numbers to obtain nontechnical or administrative support, such as hardware and software orders, hardware maintenance, services contract of entitlement, and invoices: .For commercial or state and local support operations: 1-877-426-6006 (Listen to the voice prompts) .For business partner support operations: 1-800-426-9990 .For federal government support operations: 1-800-333-6705 ------------------------------------------------------------------------------- 2.0 Prerequisites for SDD It is recommended that the user to upgrade the HP/UX to the standard patch or higher: 1. 11i 11.23 - Dec 05 (Standard Patch Bundles) plus PHKL_33827 for Fibre Channel Mass Storage patch 2. 11i 11.11 - Sep 05 (Quality Plus Bundles) ------------------------------------------------------------------------------- 3.0 SDD Change History =============================================================================== 3.1 Defects Fixed 4958 -- System crash during write SDD trace buffer from kernel space to user space 4977 -- "datapath query device -i 1" where interval 1 was not handled correctly 4978 -- hd2vp and vp2hd to handle SDD PVlink VG conversion for VG name with vg00 prefix but exclude vg00. 5075 -- A DS8K volume can be any number of arrays, not just one array 5209 -- SDD crashes while opening the device due to recursive spinlock 3.1.1 Common Notes: 1. Starting the SDD server manually If the SDD server does not start automatically after you perform the SDD installation or you want to start it manually after stopping sddsrv, use the following process to start sddsrv: 1. Edit /etc/inittab and verify the sddsrv entry. For example: srv:23456:respawn:/sbin/sddsrv >/dev/null 2>&1 2. Save the file /etc/inittab. 3. Execute init q. 4. Follow the directions in "Verifying if the SDD server has started" to confirm that the SDD server started successfully. Perform the following steps to stop the SDD server: 1. Edit /etc/inittab and comment out the SDD server entry: #srv:23456:respawn:/sbin/sddsrv >/dev/null 2>&1 2. Save the file. 3. Execute init q. 4. Check if sddsrv is running by executing ps -ef |grep sddsrv. If sddsrv is still running, execute kill -9 pid of sddsrv. 3.1.2 ESS/DS8000/DS6000 defects 5075 -- A DS8K volume can be any number of arrays, not just one array 3.1.3 SVC defects None =============================================================================== 3.2 New Features None. Note: For the DS4000 and DS5000 support, the user should still use the v1.8.0.2 On-Demand package. If the On-Demand package is installed after the SDD v1.8.1.3 installation, the user should run "cfgvpath -r" to reconfigure the DS4000/DS5000 device. If the On-Demand package has been installed earlier, the v1.8.1.3 install process automatically recognize and configure the DS4000 or DS5000 devices. To install the DS4000 or DS5000 On-Demand-Device package, use: swinstall IBMsdd_ds4k_.depot IBMsdd_ds4k_tag swinstall IBMsdd_ds5k_.depot IBMsdd_ds5k_tag =============================================================================== 3.3 Feature Details See SDD Users' Guide =============================================================================== 3.4 Known Issues None Note: vp2hd is no longer invoked at the shutdown time and hd2vp is no longer invoked at boot time. These change were to alleviate the long boot time for large configurations. The user can ignore the vpath warning message during boot time. ================================================================================= 3.5 Correction to User's Guide 1. SDD supports the following MC Service Guard levels: 11.16 and 11.18. The following levels have been validated: - 11.16 for HPUX 11.11 and 11.23 - 11.18 for HPUX 11.23 ------------------------------------------------------------------------------ 4.0 User license agreement for IBM device drivers NOTICE: PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE PROGRAM AND DOCUMENTATION.

PLEASE READ THE | |AGREEMENT CONTAINED IN THIS BOOK BEFORE USING THE HARDWARE PRODUCT.SEE| |IBM agreement for licensed internal code. | | | +----------------------------------------------------------------------+ You accept the terms of this Agreement(3) by your initial use of a machine that contains IBM Licensed Internal Code (called "Code"). These terms apply to Code used by certain machines IBM or your reseller specifies (called "Specific Machines"). International Business Machines Corporation or one of its subsidiaries ("IBM") owns copyrights in Code or has the right to license Code. IBM or a third party owns all copies of Code, including all copies made from them. If you are the rightful possessor of a Specific Machine, IBM grants you a license to use the Code (or any replacement IBM provides) on, or in conjunction with, only the Specific Machine for which the Code is provided. IBM licenses the Code to only one rightful possessor at a time. Under each license, IBM authorizes you to do only the following: 1. execute the Code to enable the Specific Machine to function according to its Official Published Specifications (called "Specifications"); 2. make a backup or archival copy of the Code (unless IBM makes one available for your use), provided you reproduce the copyright notice and any other legend of ownership on the copy. You may use the copy only to replace the original, when necessary; and 3. execute and display the Code as necessary to maintain the Specific Machine. You agree to acquire any replacement for, or additional copy of, Code directly from IBM in accordance with IBM's standard policies and practices. You also agree to use that Code under these terms. You may transfer possession of the Code to another party only with the transfer of the Specific Machine. If you do so, you must 1) destroy all your copies of the Code that were not provided by IBM, 2) either give the other party all your IBM-provided copies of the Code or destroy them, and 3) notify the other party of these terms. IBM licenses the other party when it accepts these terms. These terms apply to all Code you acquire from any source. Your license terminates when you no longer rightfully possess the Specific Machine. Actions you must not take You agree to use the Code only as authorized above. You must not do, for example, any of the following: 1. Otherwise copy, display, transfer, adapt, modify, or distribute the Code (electronically or otherwise), except as IBM may authorize in the Specific Machine's Specifications or in writing to you; 2. Reverse assemble, reverse compile, or otherwise translate the Code unless expressly permitted by applicable law without the possibility of contractual waiver; 3. Sublicense or assign the license for the Code; or 4. Lease the Code or any copy of it. ------------------------------------------------------------------------------- 6.0 Trademarks and service marks The following terms are trademarks of the International Business Machines Corporation in the United States,other countries, or both: AIX AS/400 Enterprise Storage Server HACMP/6000 IBM IBM logo iSeries Netfinity NetVista Operating System/400 pSeries RS/6000 Seascape SP System/360 System/370 System/390 The eServer logo TotalStorage Versatile Storage Server xSeries zSeries z/Architecture z/OS Microsoft, Windows, Windows NT, and the Windows logo are registered trademarks of Microsoft Corporation.
