xiv Preface Hitachi Dynamic Link Manager (for VMware®) User Guide
1 Overview of HDLM HDLM is a software package that manages paths between a host and a storage system. HDLM is designed to distribute loads across multiple paths and will switch a given load to another path if there is a failure in the path that is currently being used, thus improving system reliability. This chapter gives an overview of HDLM and describes its features.
What is HDLM? With the widespread use of data warehousing and increasing use of multimedia data, the need for high-speed processing of large volumes of data on networks has rapidly grown. To satisfy this need, networks dedicated to the transfer of data, such as SANs, are now being used to provide access to storage systems. HDLM manages the access paths to these storage systems.
The ability to distribute a load across multiple paths. This is also known as load balancing. When a host is connected to a storage system via multiple paths, HDLM can distribute the load across all the paths. This prevents one, loaded down path from affecting the processing speed of the entire system. For details on load balancing, see Distributing a Load Using Load Balancing on page 2-8. The ability to continue running operations between a host and storage system, even if there is a failure.
1-4 Overview of HDLM Hitachi Dynamic Link Manager (for VMware®) User Guide
2 HDLM Functions This chapter describes the various functions that are built into HDLM. Before the function specifications are explained though, this chapter will go into detail about the HDLM management targets, system configuration, and basic terms that are necessary to know to effectively operate HDLM. After that, the rest of the chapter focuses on describing all the HDLM functions, including the main ones: load distribution across paths and path switching.
Devices Managed by HDLM Below is a list of devices that can or cannot be managed by HDLM. The devices that can be managed by HDLM are called HDLM management-target devices.
Figure 2-1 Configuration of an HDLM System When Using an FC-SAN The following table lists the HDLM system components when using an FCSAN. Table 2-1 HDLM System Components When Using an FC-SAN Components Description HBA A host bus adapter. This serves as a cable port on the host. FC-SAN A dedicated network that is used for the transfer of data between hosts and storage systems CHA A channel adapter P A port on a CHA. This serves as a cable port on a storage system.
system is called a port (P) on a channel adapter (CHA) used for iSCSI connections. A logical unit (LU), which lies in a storage system, is either an input target or an output target to or from a host. The areas within an LU are called Devs. A route that connects a host to a Dev in an LU is called a path. HDLM assigns a unique ID to each management-target path. This ID is called AutoPATH_ID. Sometimes, the path is also just simply called a management target.
Figure 2-3 Configuration of an IP-SAN System When Using iSCSI Software and an NIC Table 2-2 HDLM System Components When Using an IP-SAN on page 2-5 lists the HDLM system components when using an IP-SAN. Table 2-2 HDLM System Components When Using an IP-SAN Components Description iSCSI software The driver software that contains the iSCSI initiator function iSCSI HBA A host bus adapter that contains the iSCSI initiator function. This serves as a cable port on a host.
LU Configuration The following figure shows the LU configuration recognized by the host, after the installation of HDLM. Figure 2-4 LU Configuration Recognized by the Host After the Installation of HDLM The following table lists and describes the components recognized by the host. Table 2-3 Components Recognized by the Host Components Description HLU An LU that the host recognizes via the HDLM driver. This type of LU is called a host LU.
Figure 2-5 Configuration of the HDLM Programs The following table lists and describes the functions of these programs.
HDLM driver and NMP positions The HDLM driver and NMP are positioned above the SCSI driver, causing each application on a guest OS to access LUs in the storage system via the HDLM driver and NMP. The following figure shows the positioning of the HDLM driver and NMP. Figure 2-6 Positioning of HDLM Driver and NMP Distributing a Load Using Load Balancing When the system contains multiple paths to a single LU, HDLM can distribute the load across the paths by using multiple paths to transfer the I/O data.
Figure 2-7 Flow of I/O Data When the Load Balancing Function Is Not Used on page 2-9 shows the flow of I/O data when the load balancing function is not used. Figure 2-8 Flow of I/O Data When the Load Balancing Function Is Used on page 2-10 shows the flow of I/O data when the load balancing function is used. Both figures show examples of I/O operations being issued for the same LU by multiple applications.
Figure 2-8 Flow of I/O Data When the Load Balancing Function Is Used When the load balancing function is used, I/O operations are distributed via multiple paths (A, B, C, and D). This helps to prevent problems with system performance and helps prevent bottlenecks from occurring. Paths to Which Load Balancing Is Applied This subsection describes, for each type of storage system, the paths to which the load balancing function is applied.
load balancing will be performed among the remaining, usable owner paths. It is only when absolutely no owner paths are available, that load balancing is then performed among the non-owner paths. For the example in Figure 2-9 Overview of Load Balancing on page 2-11, suppose that in the owner controller of LU0 is CHA0. When the LU is accessed, the load is balanced between the two paths A and B, which are both owner paths.
Load Balancing Algorithms The load balancing function uses VMware vSphere PSPs or PSPs provided by HDLM. The following table lists the load balancing algorithms that HDLM can use.
You can specify the load balancing function by the dlnkmgr command's set operation. For details on the set operation, see set (Sets Up the Operating Environment) on page 6-16. Performing Failovers and Failbacks Using Path Switching When the system contains multiple paths to an LU and an error occurs on the path that is currently being used, HDLM can switch to another functional path, so that the system can continue operating. This is called a failover.
For details on error levels, see Table 8-1 Format and Meaning of the Message ID KAPLnnnnn-l on page 8-2 in Format and Meaning of Message IDs on page 8-2.. When the Hitachi AMS/WMS series is being used, HDLM will select the path to be used next from among the various paths that access the same LU, starting with owner paths, and then non-owner paths. For example, in Figure 2-10 Path Switching on page 2-15, the owner controller of an LU is CHA0, and access to the LU is made via only one path (A).
Figure 2-10 Path Switching Automatic Failbacks When a path recovers from an error, HDLM can automatically place the recovered path back online. This function is called the automatic failback function. When using the Hitachi AMS/WMS series, HDLM will select the next path to be used first from among the online owner paths, and then from the online nonowner paths.
When an intermittent error#2 occurs in a path, automatic failback repeatedly places the path offline and then online again, which can cause I/O performance to drop. In this case, we recommend that you configure intermittent error monitoring to exclude paths with intermittent errors from the automatic failback process. Automatic failback is implemented by functionality provided by VMware vSphere ESXi, and cannot be disabled. Intermittent error monitoring can be specified in the HDLM command's set operation.
then from online non-owner paths. When the Universal Storage Platform V/VM series, Virtual Storage Platform series, VSP G1000 series, Hitachi AMS2000 series#, Hitachi SMS series#, or HUS100 series# is being used, because all the paths are owner paths, the path to use is not switched even if you change the path status to online. # This storage system applies when the dynamic I/O path control function is disabled.
The status indicating that an I/O could not be issued on a given path, because an error occurred on the path. The (E) in Offline(E) indicates the error attribute, which indicates that an error occurred in the path. Correspondence between VMware vSphere and HDLM path statuses The following table shows the correspondence between the path statuses displayed by VMware vSphere and the path statuses displayed in the output of the HDLM command's view operation.
Online operation: Online operation performed by executing the dlnkmgr command's online operation. Offline operation: Offline operation performed by executing the dlnkmgr command's offline operation. Figure 2-12 Path Status Transitions (P-VOL in HAM environment) Legend: Online operation: Online operation performed by executing the dlnkmgr command's online operation. Offline operation: Offline operation performed by executing the dlnkmgr command's offline operation.
Note: If there is a path failure immediately after a path is placed offline by using the dlnkmgr command, Offline(C) might change to Offline(E). If an offline operation was performed, wait for a fixed period of time (about 2 minute), check the path status by using the dlnkmgr command, and make sure that the status has changed to Offline(C). If it is Offline(E), retry the offline operation.
Intermittent Error Monitoring Actions During intermittent error monitoring, HDLM manages the history of errors# that occurred on each path. If an error occurs on a path, HDLM counts the number of errors that occurred within the time period specified as the error monitoring interval, immediately before that error occurred. If the number reaches the specified condition, then an intermittent error will occur on the path.
change the paths to the blocked state (Offline(C)) before you change the intermittent error monitoring setting. You can check whether intermittent error monitoring is being performed for a path, by executing the HDLM command's view -path operation with the -iem parameter specified, and then checking the displayed IEP item. If a numerical value of 0 or greater is displayed for this item, intermittent error monitoring is being performed on the path.
# For using the dynamic load balance controller function there are restrictions on the versions of the microprograms you install. For details, see the release notes of HDLM. Dynamic I/O Path Control Function In a storage system in which the dynamic load balance controller function is installed, enable the dynamic I/O path control function to make the HDLM load balancing effective.
Figure 2-13 Flow of Data When Path Error Information Is Collected Logs might be collected in layers below HDLM, such as for the SCSI driver. For more details, see the VMware vSphere documentation. Types of Collected Logs HDLM collects information about errors that occurred on ESXi hosts and on a remote management client. • Log data for errors that occurred on the ESXi host is output to syslog on the ESXi host, This log data corresponds to I/O errors and to changes in path status.
Table 2-8 Types of ESXi Host Error Information Log name Syslog Description Output destination Information about detected errors is The default file path collected. is /var/log/vmkernel.log. For details on how to set the syslog file path, refer to the VMware vSphere documentation. For details on how to change the collection level, see Table 8-1 Format and Meaning of the Message ID KAPLnnnnn-l on page 8-2 in Format and Meaning of Message IDs on page 8-2.
In Windows Server 2003 (excluding the x86 edition) and Windows Server 2008 (excluding the x86 edition), Program Files is Program Files (x86). #2 The underlined part indicates a folder specified during installation. After obtaining these files, be sure to also copy them to a backup location. Collecting Error Information You need to collect HDLM error information both from the ESXi host and from remote management clients.

3 Creating an HDLM Environment This chapter explains how to set up an HDLM environment and also how to erase environment settings. Make sure that you have already installed HDLM and configured the function settings.
HDLM System Requirements Check the following before installing HDLM: For the requirements for using HDLM in an HAM environment, see the release notes of HDLM. Hosts and OSs Supported by HDLM HDLM can be installed on computers running the following operating systems: Host OS support The following versions of VMware vSphere ESXi are supported as an OS for host computers: • VMware vSphere ESXi 5.0 Enterprise Edition/Enterprise Plus Edition • VMware vSphere ESXi 5.
A remote management client can run on a machine in the same LAN as the host, or on a guest OS installed on the host itself. VMware vSphere CLI 5.0/5.1/5.5 is a prerequisite program for a remote management client. Make sure that VMware vSphere CLI is installed before installing HDLM.
Disk Requirements The disk space requirements for hosts and remote management clients are as follows: • Host 600KB • Remote management client 175 MB Number of LUs and Paths That Are Supported in HDLM The following table lists the number of LUs and paths that are supported by HDLM.
Installing HDLM on a server on which HDLM has not been installed is called a new installation of HDLM. Upgrade installation of HDLM: Installing a newer version of HDLM over the existing version without removing the existing version is called an upgrade installation of HDLM. Re-installation of HDLM: A re-installation of HDLM involves installing the same version of HDLM again to repair an existing installation. You must remove HDLM before reinstalling it.
• At the auto deploy server, apply the host profile of the relevant host. Unless you apply the host profile, HDLM setting changes will not be saved when the host restarts. If you install HDLM while the Startup Type setting for the Windows Installer service is disabled or while another program is using the Windows Installer service, the installation might fail. If this problem occurs, make sure that both of the above conditions are satisfied, and then install HDLM again.
When performing a new installation on a remote management client, you can perform an unattended installation by using the HDLM install utility (installhdlm). An unattended installation enables a user to install HDLM without entering information during processing. For details on the installhdlm utility, see The installhdlm Utility for Installing HDLM on page 7-8.

If you are managing HDLM by using Global Link Manager, set up the host and remote management client by following the procedure described in Settings When Managing HDLM by Using Global Link Manager on page 3-11.
Host settings • Create a user account. Remote management client settings • Add the host to the Credential Store file. • Execute the utility for configuring HDLM remote management client environments (dlmrmcenv). • Specify Windows Firewall settings. Creating a user account A user account used for performing operations on the host from the remote management client needs to be created on the host. Use either of the choices below for the user account name.
In addition, if you add the host by specifying the host name from Global Link Manager, configure the settings so that the host name of the ESXi host on the remote management client can be resolved to the IP address. The Credential Store file stores the host information (host name, user name, and password) that is managed by VMware vSphere CLI. The default storage location of the Credential Store is as follows: %APPDATA%\VMware\credstore\vicredentials.
2. Execute the firewall_setup command. 3. Check the displayed message to make sure that the command was executed successfully. The command ended successfully. firewall_setup command syntax The firewall_setup command registers ports used by Hitachi Command Suite Common Agent Component into the exceptions list of Windows Firewall running on the remote management client. The firewall_setup command is stored in the following location, depending on whether the Device Manager agent is installed.
Note: The folder that stores the Hitachi Command Suite Common Agent Component commands is automatically added to the PATH environment variable of the remote management client. So, when executing the command, there is no need to move the current folder to the folder storing the command. Checking the Path Configuration HDLM functions, such as load balancing and failover, are only available for HDLM management-target devices that have more than one active path.
Checking the Current Settings Check the current settings by executing the following command to set the HDLM functionality by using the dlnkmgr command's view operation.

4 HDLM Operation This chapter describes the procedures for operating HDLM. This includes how to operate HDLM and the HDLM manager, and how to change the configuration of the operating environment.
HDLM Operations Using Commands This section explains how to use the HDLM command. For details on the various command operations, see Chapter 6, Command Reference on page 6-1. Notes on Using Commands • Execute the HDLM command from the VMware vSphere CLI on the remote management client. • To specify a parameter value containing one or more spaces, enclose the entire value in double quotation marks (").
PROMPT> For details on the displayed items and their descriptions, see view (Displays Information) on page 6-25. Changing the Status of Paths This section explains how to change path statuses. Changing the Status of Paths to Online To change the status of paths to online: 1. Check the current status of the paths. To place paths online by specifying a CHA port, single path, or HBA port WWN, check the path name or PATH_ID used to manage the path.
dlnkmgr -s host-name -u user-name -p password view -path 2. To change the status of paths to Offline(C), execute the dlnkmgr command's offline operation. The paths to be placed Offline(C) can be specified by using a CHA port, single path, or HBA port WWN. For details on how to specify paths, see offline (Places Paths Offline) on page 6-7. For example, to place a specific path offline, execute the HDLM command's offline operation with the -pathid parameter specified.
Initializing Statistical Information for Paths This section explains how to initialize statistical information (I/O counts and I/O errors) for all the paths managed by HDLM. This procedure is useful when you want to check the number of I/O operations and I/O errors that have occurred since the last time the I/O counts and I/O errors were initialized to 0. 1. Check the current status of the path.
PROMPT> To display the operating environment of the audit log, execute the HDLM command's view operation with the -sys and -audlog parameters specified. The following example shows how to execute the command: PROMPT>dlnkmgr -l view -sys -audlog Audit Log : off Audit Log Category : KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = yyyy/mm/dd hh:mm:ss PROMPT> For details on the displayed items and their descriptions, see view (Displays Information) on page 6-25.
To display license information, execute the dlnkmgr command's view operation with the -sys and -lic parameters specified. The following is an example of executing the command: PROMPT>dlnkmgr -l view -sys -lic License Type Expiration Permanent KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = yyyy/mm/dd hh:mm:ss PROMPT> For details on the displayed items and their descriptions, see view (Displays Information) on page 6-25.
To display HDLM version information, execute the dlnkmgr command's view operation with the -sys parameter specified.

HDLM Resident Processes The table below lists and describes the resident processes in HDLM. To monitor these processes, use the names below. Table 4-1 HDLM resident processes Process Service Description dlmmgr.exe HDLM Manager for VMware HDLM manager process hbsa_service.
5 Troubleshooting This chapter describes how to properly use HDLM error information, and then how to resolve the problem, if an error has occurred in HDLM. The resolutions for path errors, HDLM program errors, and other types of errors are all described separately. If you need technical support, see Getting help on page xiii.
Collecting Error Information Collect the error information immediately after an error occurs. If the computer is restarted, the error information might be deleted and you will be unable to collect it. For details about how to collect error information, see Collecting Error Information on page 2-26. Checking Error Information in Messages You can check path errors by referring to the KAPL20023-E message output to the syslog.
Figure 5-2 Troubleshooting Procedure When a Path Error Occurs The following shows the procedure for using the HDLM command (dlnkmgr) to handle a path error. Examining the Messages Examine the message that is output to syslog in the host by using applications or tools for monitoring messages. If the KAPL20023-E message is output, view the message to check the path in which the error has occurred. For details on each item displayed in messages, see Checking Error Information in Messages on page 5-2.
Narrowing Down the Hardware That Might Have Caused the Error Check the DskName, iLU, ChaPort, and HBAPortWWN columns of the path with the error to narrow down the hardware that may be the cause of the error. To physically identify the hardware corresponding to DskName, iLU, and ChaPort, use the information provided by the storage-system management program.
Figure 5-3 Troubleshooting Procedure When a Program Error Occurs The following shows the procedure for handling a program error by using the HDLM command (dlnkmgr). Examining the Messages Examine the messages that are output to the host syslog. If an error occurs in an HDLM program, a message is output to syslog. Examine the content of the message. Messages with error level E (Error) or higher require corrective action.

Glossary This glossary explains the terms used in this manual. A automatic failback A function for checking the status of paths at regular intervals, and automatically placing the status of a path recovered from an error into the Online status. If a path with an Offline(E) status recovers from an error, an automatic failback will place the path Online.
CLPR(Cache Logical Partition) A function supported by the Universal Storage Platform V/VM series, Virtual Storage Platform series, VSP G1000 series, Hitachi AMS2000/AMS/WMS/SMS series, HUS100 series, and HUS VM for logically splitting up a cache. This function can split up a cache into parity groups in the storage system, so that other parity groups do not affect the cache performance. D Dev (Device) A target that HDLM controls and operates. A Dev is called a device in VMware vSphere.
H HAM environment An environment in which volume pairs that are synchronized between two storage systems are created by HAM (High Availability Manager), and hosts are configured to recognize these volumes as one volume. An HAM environment consists of the primary volume (P-VOL) in the primary site and the secondary volume (S-VOL) in the secondary site. When an error occurs on one of the volumes, the path can be switched to the other volume by using HDLM.
L LDEV (Logical Device) A combination of the storage system's product name, serial number, and an internal LU. HDLM uses this value to identify a particular LU. load balancing Functionality for distributing the load across the paths that access each area within an LU. To distribute loads, load balancing uses multiple paths to perform I/O operations. Load balancing uses VMware vSphere PSPs.
owner path A path that passes through an owner controller for an LU in the Hitachi AMS/WMS series. A path that passes through a controller other than an owner controller is called a non-owner path. When using the Universal Storage Platform V/VM series, Virtual Storage Platform series, VSP G1000 series, Hitachi AMS2000 series#, Hitachi SMS series#, HUS100 series#, or HUS VM, all paths are owner paths.
the LU cannot be accessed from multiple paths (coming from multiple hosts) simultaneously. However, because of this, load balancing is not possible. (See also: persistent reservation) S SAN (Storage Area Network) A high-speed network connecting hosts to storage systems. This network is independent of a LAN and is dedicated to data transfers. A SAN provides faster access to storage systems, and prevents the transfer of high-volumes of data from deteriorating LAN performance. SCSI device A SCSI disk device.
