HP StorageWorks Command View XP Version 1.8A Release Date: March 2004 Readme.txt/Readme.htm Part Number: B9357-96086 ==================================== ==================================== ======== CONTENTS ======== 1.0 OVERVIEW 2.0 NEW FEATURES 3.0 DEFECTS FIXES 4.0 KNOWN ISSUES ============= 1.0 OVERVIEW ============= HP StorageWorks Command View XP is a Web-based storage management platform that monitors and configures the HP StorageWorks XP Disk Array family of products. HP StorageWorks Path Connectivity XP is a component included with Command View. You can access Command View from remote locations using the Internet and a Web browser. New features and defect fixes are summarized in sections 2.0 and 3.0. Section 4.0 discusses known issues. ================= 2.0 NEW FEATURES ================= This version of Command View provides support for new firmware features, product enhancements, and defect fixes for the XP disk arrays. For the XP128/XP1024 with firmware version 21.08.05 or later, the following is supported: - Web GUI enhancements to support XP NAS feature. This feature is documented in Chapter 11, LUN Management for the XP128/XP1024, of the HP StorageWorks Command View XP Users Guide, and it appears under the Cache LUN tab in the Command View GUI. The following support for Path Connectivity has been added: - Windows 2003 Server (64-bit) hosts Unless otherwise noted in this document, all new features are described in the appropriate installation and user guides. ================= 3.0 DEFECT FIXES ================= 3.1 New Defect Fix for Command View This version of Command View fixes one defect by providing the following solution: - After a CLI set operation is successful, the respective get operation gives updated data immediately. 3.2 New Defect Fixes for Path Connectivity This version of Path Connectivity fixes several defects by providing the following solutions: - Command View Path Connectivity and Secure Path under Windows 2003 Server can now coexist on the same host. - The appropriate file is now created when performing a local Windows Host Agent installation on a host that did not previously have the Host Agent installed. This eliminates authentication errors that were seen on the management station during Path Connectivity host data collection. - The Host Agent deployment tool (local update) works when trying to update the host agent from a lower to a higher version of Command View. - It is possible to uninstall CV 1.7B host agent using the CV 1.8A host agent deployment tool. ================= 4.0 KNOWN ISSUES ================= The issues addressed in this section are known to exist for Command View and Path Connectivity. 4.1 General limitations ------------------------ The following are not supported: - No support for BC/CA configuration on the XP48/XP256/ XP512 - No host agent, CLI, API, or online help support for mainframe systems - No mainframe support on the XP48/XP256/XP512 - No support for Netscape browsers on Microsoft Windows platforms Issues concerning Command View ============================== 4.2 Viewing online help on HP-UX --------------------------------- The Command View online help may not load properly on HP-UX operating systems using Netscape. If this occurs, reload the frame by right-clicking the grayed frame on the left hand side and clicking Reload Frame. 4.3 The list of managed XP disk arrays may be lost when upgrading software -------------------------------------------------------- If you are upgrading from Command View XP 1.51 or earlier, Command View will lose the list of managed XP disk arrays during the upgrade process. To minimize impact of this constraint, record network related information about the XP disk arrays managed by Command View prior to upgrading, and then manually add the XP disk arrays afterwards. 4.4 Mozilla 1.2.1.01 on HP-UX 11.23 limitation when adding XP disk arrays in the Device Administration screen ----------------------------------------------------------- If you are using Mozilla 1.2.1.01 on HP-UX 11.23 and you try to add an XP disk array using the Device Administration screen by entering the IP address, data does not populate the form. To work around this problem, add the XP disk array by using any of the other supported operating systems and browsers, or by using the “create device” CLI command. After adding the XP disk array through one of the supported methods, you can use Mozilla 1.2.1.01 on HP-UX 11.23 to complete any other configuration on an XP disk array. 4.5 Multiple LAN card limitation --------------------------------- If the Command View management station has two network cards installed, one card on an isolated LAN and another on a corporate LAN, the client may have trouble connecting to the management station if the primary card mapped to the local host is on a different LAN than the client. To solve this issue, configure the first LAN card to communicate with the hosts and Command View API clients on the SAN. To set the LAN card as the first network card, modify the bindings order of the network adapters to bind that network card first. This procedure is explained in the installation guide. 4.6 The CV CLI "create host_group" command removes spaces in host group name input parameters ------------------------------------------------------------- If the "create host_group" command removes spaces in host group name input parameters, use the host group names with no spaces in the CLI. 4.7 Command View 1.8A and Performance Advisor 1.7 do not use the same JRE version --------------------------------------------------------- Performance Advisor 1.7 uses an older JRE version than the JRE version supported by Command View 1.8A. Using an older JRE than the one supported for Command View 1.8A may cause display problems. To solve this, obtain Performance Advisor 1.7-2 or later and follow the upgrade instructions provided with the product. 4.8 Installing multiple JRE versions may cause Command View 1.8A applets to crash Internet Explorer ------------------------------------------------------- In Windows, installing an older or unsupported JRE after installing the supported JRE will cause Command View 1.8A to crash. First, verify the order you installed the JRE versions and if necessary, uninstall and re-install JRE 1.4.2. Complete the following: 1. Check the timestamps of the JRE installation folders. The JRE 1.3.1 installation folder path is /JavaSoft/JRE/1.3.x. The JRE 1.4.2 installation folder path is /Java/j2re1.4.2. If the JRE 1.3.x installation folder has a more recent timestamp than the JRE 1.4.2 installation folder, continue to the next step. 2. If you are solving the problem on the management station, stop all Command View or Performance Advisor services. 3. Uninstall JRE 1.4.2. 4. Download and install JRE 1.4.2 from the Sun Web site. 5. If you are solving the problem on the management station, restart all Command View or Performance Advisor services before using Command View or Performance Advisor. 4.9 OPEN-V CV CLI Support -------------------------- At this time, OPEN-V is not fully supported by the CLI, but is supported by the Command View GUI. The CLI will display OPEN-V volumes, but will not create OPEN-V volumes. 4.10 SSL Support for XP128/XP1024 GUI -------------------------------------- Starting with firmware version 21.07.04, SSL is supported on the Web server on the SVP, but when used with Command View XP, GUI cannot successfully provide access to the XP disk array. Therefore, SSL is not supported at this time in this configuration. 4.11 Auto LUN support for the XP48/XP512 ----------------------------------------- For active management of Auto LUN on the XP48/XP512, HP recommends using Remote Control XP instead of the Command View XP GUI because Remote Control provides significantly quicker performance. 4.12 XP256 disk array limitations --------------------------------- Due to performance limitations, we do not recommend use of HP StorageWorks Command View XP to actively manage XP256 disk arrays, but only to monitor their usage. The Remote Control software accompanying the purchase of HP Surestore Command View XP for the XP256 array may be used successfully to actively configure the XP256 disk array. Remote Control XP is available as B9357AD, Command View Remote Control LTU U/G. 4.13 Command View CLI documentation version -------------------------------------------- The HP StorageWorks Command View XP Command Line Interface Reference Guide references Command View 1.8; however, it also supports Command View 1.8A. Issues concerning Path Connectivity =================================== 4.14 Multiple Path Connectivity instances in a SAN --------------------------------------------------- When communicating to an XP48/XP256/XP512, if you have multiple Command View management stations configured in your SAN environment to manage the same SAN resources, Path Connectivity's "Data Collection Service" may conflict each other. For instance, the Path Connectivity Diagnosis function either hangs or takes a very long time to complete. To work around this issue, disable the Path Connectivity "Data Collection Service" on one of the management stations. To do this, go to the Windows Services, right-click "HpssDataCollectorService," and click Stop. 4.15 Not preserving original data in new Path Connectivity database ----------------------------------------------------------- If you are upgrading from Command View XP 1.40 or earlier, the installation process will not preserve the user-entered database data. The database content will be lost during the upgrade process. 4.16 The Connectivity Health Screen will not show physical path information for a Solaris host with Sun's Traffic Manager (MPxIO) enabled ----------------------------------------------------------- The Connectivity Health screen provides a table of the paths and path connectivity health statuses between hosts and XP disk arrays. However, for a Solaris host with Sun's Traffic Manager (MPxIO) enabled, the Connectivity Health screen will show a pseudo HBA WWN and a logical path between this pseudo HBA port to the XP disk array. 4.17 A "No such object in table" error may occur while accessing the Administration screens in Path Connectivity ------------------------------------------------------- A "No such object in table" error may occur while accessing the Administration screens in Path Connectivity. This error could occur when attempting to manually add a host on the Host Discovery - Host Management screen or other Path Connectivity Administration feature combined with a subsequent network delay or timeout during the requested operation. To resolve this issue, you need to restart the HPSSE2ETomcat service. You can choose to either restart the Command View services through the Start menu: Note: The following procedure stops and restarts ALL Command View services and will affect processes that are currently making changes to disk array configurations. - Click Start > Programs > HP StorageWorks Command View XP > Restart Services. OR Restart the HPSSE2ETomcat service remotely: 1. Become a member of the \ Administrators group. 2. From the Control Panel, click Administrator Tools > Computer Management > Action > Connect to another computer, and then connect to . 3. From the Control Panel, click Administrator Tools > Computer Management > Services and Applications > Services. 4. Stop and Start the HpssE2ETomcat service. Or use the REXEC service: - rexec [-l username] [-n] "NET STOP HpssE2ETomcat" - rexec [-l username] [-n] "NET START HpssE2ETomcat" 4.18 A Command View management station on Windows NT may fail to deploy host agents remotely --------------------------------------------------------- If the only management station is on a Windows NT machine, we recommend that you deploy the host agent locally. Refer to the installation guide for further details on installing the host agent locally. 4.19 Switch requirements ------------------------- The Path Connectivity module does NOT support the Cisco family of switches. 4.20 Path Connectivity Host Agent installation ----------------------------------------------- If your hosts have host agent with version of CV 1.7B or earlier, you will need to update your host agent version to CV 1.8A in order to use Path Connectivity. If your hosts have CV 1.8A host agent installed, you do NOT need to update your host agent. For Windows Server 2003 (32-bit), you must perform a fresh local installation of the corresponding host agent. The update and install functions using the remote deployment tool are not supported for host agents on Windows. For host agents installed using Command View version before CV 1.6, please uninstall the old host agent locally and then install the new host agent. For host agents installed using CV 1.6 and later, you can locally install the host agent by invoking the install script in the local install package without uninstalling first. For detailed instructions regarding the local installation and uninstallation procedures, please refer to the HP StorageWorks Command View XP Installation Guide. 4.21 Host Agent properties do not display in Add/Remove Programs -------------------------------------------------------- For Windows Server 2003 (32-bit) hosts, the Host Agent's size does not display in Add/Remove Programs. This field is blank. For all supported Windows hosts, the Host Agent's version does not display in Add/Remove Programs. This field is blank. 4.22 Path Connectivity CLI documentation version ------------------------------------------------- The HP StorageWorks Command View XP Path Connectivity Command Line Interface Reference Guide references Command View 1.8; however, it also supports Command View 1.8A.
