Preface This guide explains how to migrate data from one storage system parity group to another using the HP StorageWorks P9000 Tiered Storage Manager command line interface (CLI). Besides command syntax and parameters, topics include CLI requirements, setup, and troubleshooting.
Preface
1 Overview of the CLI This chapter contains a list of the CLI commands and gives an overview of volume operations. List of the CLI commands The CLI enables you to obtain storage domain information; create storage tiers and migration groups; and shred, lock, and unlock volumes. The following table provides an overview of each command. Table 1 Overview of CLI commands Category Command name Description GetStorageDomains Obtains information about storage domains. Changes attributes for a storage domain.
Category Command name Description Changes attributes for a migration group.
Volume operations using the CLI The following figure shows the flow of volume operations when the CLI is used. Figure 1 Flow of volume operations You can also execute tasks when you create them. By using the CLI, you can migrate a specified migration group. Use the GUI if you want to migrate a specified volume. Only the CLI can be used to create locking, unlocking, or shredding tasks. These tasks cannot be created from the GUI. The CLI cannot manage migration tasks created by using the GUI.
Overview of the CLI
2 Preparations for executing the CLI This chapter explains the preparations to perform before starting to use the CLI. More specifically, this chapter explains how to set up the CLI and an environment for the CLI. Setting up the CLI You can operate the CLI on either a management server or a management client. This section describes how to set up the CLI on a management client.
4. Execute the setup batch file setup.bat from the command prompt, as follows: system-drive\TieredStorageManager\Tiered-Storage-Manager-version\Setup\setup.bat The setup.bat file stores and sets up the common library for collecting trace information, and edits the CLI execution batch file. The common library is stored in the following folder: system-drive\Program Files\Hitachi\HNTRLib2 NOTE: Note the following about executing setup.
2. Use FTP or external storage media to transfer the setup file from the Tiered Storage Manager software management server to the management client. You can transfer the setup file to any location, such as /tmp.
The uninstallation batch file or shell script is located in the same directory as the setup batch file or shell script. Uninstalling the CLI from a Windows system To uninstall the CLI from a Windows system: 1. Back up the htsmcli.properties file. If you are no longer going to use the CLI on the computer it is installed on, you do not need to back up this file. 2.
Preparations after setup This section explains the preparations that must be performed to execute the CLI commands after you have set up the CLI. Setting up the htsmcli.properties file Each time you execute the CLI, you need to enter the server location, user name, password, and whether to use SSL communication. In order to skip this step, you can specify the server location and common options in the htsmcli.properties file in advance.
How to use the htsmaccount command This section describes the htsmaccount command, which encodes a password and outputs it to the htsmcli.properties file or password file.
After the command completes, you do not need to specify the password when using the CLI. After the htsmaccount command finishes and the CLI is set up, use the GetStorageDomains command to make sure that the password is correctly set. Change the access permission for the CLI/logs folder In Windows, before using the CLI, change the access permissions to the CLI/logs folder so that the user accounts that use the CLI can read data from and write data to that folder.
Setting up SSL communication To use SSL to communicate with the Tiered Storage Manager server, you need to set up an environment on Tiered Storage Manager server and the management client that executes the Tiered Storage Manager CLI. For details about how to specify the security communication settings, see the HP P9000 Command View Advanced Edition Suite Software Administrator Guide.
3 Using CLI commands This chapter provides the information required to use CLI commands. This chapter also explains the user permissions, storage location, syntax, and parameter formats of CLI commands. CLI commands and user permissions Before CLI commands are executed, settings for users who will execute the commands need to be specified. Use the GUI to specify these settings. For details about how to set user permissions, see the HP P9000 Command View Advanced Edition Suite Software User Guide.

system-drive\TieredStorageManager\Tiered-Storage-Manager-version\CLI\htsmcli arguments In Solaris, HP-UX, or Linux: # ./htsmcli arguments If you execute a command without specifying any arguments in the command line, the CLI version and the syntax for displaying Help are displayed. NOTE: Note the following points on CLI execution: • If you have cancelled a CLI command by using the Ctrl + C keys or by closing the window, the command execution result cannot be checked.
If the value of an argument specified in the htsmcli.properties file and the value specified on the command line differ, the value specified from the command line takes precedence over the value in the property file. The description of each argument is provided below. server-location Specify the location of the Tiered Storage Manager server by using the following format: rmi://host-name-or-IP-address:port/HTSMServer (For example, specify a value such as rmi://myhost.mydomain:20352/HTSMServer.
parameters Parameters contain information passed to the server as part of a request. The parameters required depend on the command requested. Each parameter consists of a name and a value. Options common to all CLI commands There are two kinds of options: those common to all CLI commands, and those used for only some CLI commands. This subsection describes the options common to all CLI commands. If an argument needs to be specified after an option, specify the argument as a single character string.
#1 The --password option or the option.password property in the htsmcli.properties file, which corresponds to the --password option, can be used to specify a plain-text password. The htsmaccount command can be used to specify an encoded character string. Specify a password via the method of your choosing. For details on how to specifying a password as an encoded character string, see “Encoding the password in the property file or password file” on page 23.
is useful when specifying values for command parameters, because it also explains whether values are case sensitive and whether an empty character string can be specified. CLI command return responses and output information The CLI returns a return value after it has finished executing a process. The following two types of CLI return values exist: • If the return value is 0 or a positive value, the CLI has terminated normally.
A description of the specified command is displayed, including the correct format and parameters.
4 Filter conditions that can be used in the CLI This chapter provides an overview of the filter condition expressions that can be specified for the filtercondition parameter and the newfiltercondition parameter, and describes the syntax and properties that can be specified for filter condition expressions.
Filter name and function Filter condition expressions for volumes (volume-filter-condition) Description and commands that have access to the filter Specifiable properties Filter condition expressions used to filter storage domains and volumes in storage tiers Commands that have access to this filter type: See Table 5 and Table 8.
comparison-predicate ::= symbol comp-op literal symbol ::= name comp-op ::= "=" | "<>" | "<" | ">" | "<=" | ">=" | "startsWith" | "contains"| "endsWith" literal ::= string-literal | numeric-literal numeric-literal ::= digit { digit } digit ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" The following is an explanation of repetitive specifications: • Curly brackets ({}) indicate 0 or more repetitions. • One filter condition expression can contain a maximum of 30 comparison-predicate values.
Format of properties for which multiple elements can be specified You can specify multiple elements for some properties by using commas to separate elements. If there are no restrictions on the specifiable characters for each element, follow the rules below. Note that, even if you specify only one element for a property, you must follow these rules.
Properties overview This section provides an overview of the properties for filter conditions expressions that can be specified for given management targets (volumes, pools, or unused capacity).
Property name Description FDChipType The chip type of the flash memory (detailed type) Host The name of the host Label Label specified for a volume PoolId The pool number A port name and host storage domain name PortHostStorageDomain#1 This property compares the specified port and host storage domain name (in the format port/host-storage-domain-name) with the ports and host storage domain names (in the format port/ host-storage-domain-name) registered in Tiered Storage Manager software.
#2 This property is provided to maintain compatibility with previous versions. To specify a new filter condition, use SubsystemDisplayModel.
In addition, when using the operators below, there are restrictions on how spaces can be specified. However, note that an exception exists for the Label property. For details, see the explanation about the Label property in Table 8. • =, <>: You cannot specify spaces at the beginning or the end. • startsWith: You cannot specify spaces at the beginning.

• When a refresh is required for the storage domain • The migration group specified for the migrationgroupname parameter at the creation of a task is specified for the migrationgroupname or movetomigrationgroupname parameter in a task that has not ended (End) Other than the above, depending on the type of task, there are conditions under which the task cannot be created. For details, see the commands used to create the task. A task ID is assigned to all created tasks.
• The migration task is changed to the terminated (canceled) status by using the CancelTask command. • The migration task ends with a failure. Once migration terminates normally, the controller LDEV numbers of the migration source and target volumes are swapped. Note that the labels assigned to the volumes remain the same. If you want to change these labels along with migration, do so after the migration task is executed.
NOTE: Depending on filter conditions specified for the target storage tier, even if the migration has terminated normally, the migration source volumes might not be included in the target storage tier.
Parameter Details Specify whether the unused capacity in the migration-target volume is to be released after migration terminates normally. • Yes: Release the unused capacity.

Details of CLI commands
6 CLI property files This chapter describes how to specify options and parameters by using the CLI property files. It also explains the properties pertaining to the CLI trace log. Overview of property files for the CLI There are two property files for the CLI. • Properties pertaining to CLI options and parameters are in the htsmcli.properties file • Properties pertaining to the CLI trace log are in the htsmclienv.properties file By default, the files htsmcli.properties and htsmclienv.
In the CLI property files, any line that starts with a hash mark (#) is treated as a comment. Literal strings or numbers do not need to be enclosed in quotation marks. In Java property files, the backslash character (\) is a reserved escape character, and any character following it is treated as a tab, line-feed, or other control character. Because absolute path names on Windows platform generally contain backslashes, each path separator must be preceded by another backslash.
Property Value option.password2 No corresponding argument option.secure --secure option parameter.parameter-name Parameter specified by using a combination name and value NOTE: Only printable characters, (that is ASCII characters and \u0020 - \u007E (which are recognized as ASCII characters)) can be used for property values in the htsmcli.properties file. The following table lists example values for the location of the Tiered Storage Manager server, as well as other options, in the htsmcli.
For details about how to specify the value of this property, see the explanation of the --username option in “Options common to all CLI commands” on page 31. option.password property This property specifies the password that corresponds to the user specified for the option.username property. For details about how to specify the value of this property, see the explanation of the --password option in “Options common to all CLI commands” on page 31.
For details about how to specify the value of each command parameter, see “Command parameters” on page 32, and the details about each command. Specifying properties for the trace log in the htsmclienv.properties file Values for CLI log output functions can be set in the htsmclienv.properties file. NOTE: Note the following about the characters that can be specified in the htsmclienv.
TIP: In Solaris, HP-UX, or Linux, CLI trace log files are output with the access permissions -rw-rw-rw-, because the script htsmcli is running using umask 0 . logger.filePath property This property specifies the name of the file to which the trace log data is output, using an absolute path, or a relative path from the CLI installation directory. n.log is automatically appended to the specified file name (where n is a positive integer indicating the log file number).
With the CLI, an output level of 0, 10, 20, or 30 is set based on the content of the log output message, regardless of whether the type of error message is error, warning, or information. Only messages whose output level is less than or equal to the value set for this property are output to the trace log. This property can be set to a value from 0 to 30, but HP recommends the default output level of 20.

7 Troubleshooting This chapter explains what to do when CLI problems occur. Troubleshooting the CLI If a CLI problem occurs, do the following: • Make sure that the cause is not a software, computer, or LAN hardware problem, and then restart the computer. • Make sure that no problems exist with the Tiered Storage Manager server. The following table lists details about troubleshooting problems specific to the CLI. Table 90 Troubleshooting the CLI Problem You cannot log in to Tiered Storage Manager software.
Problem An error indicating that the specified command was not found occurred. Cause Recommended action The environment variable HTSM_CLI_HOME has not been specified. Specify the directory containing the htsmcli.properties file in the environment variable HTSM_CLI_HOME. The path to java.exe (or java) has been specified incorrectly or has not been specified. Specify the path of the java command in the environment variable HTSM_CLI_JRE_PATH.
Problem Cause Recommended action The security level of the Tiered Storage Manager server does not match the security level of the CLI. When the security level of the Tiered Storage Manager server changes, the security level must be set again for SSL communication by the CLI.# The content of the specified electronic certificate file is invalid. Use the electronic certificate file downloaded from the Tiered Storage Manager server.# The SSL communication port setting is invalid.

A Reference information during operations This appendix contains information that can be referenced when you use the Tiered Storage Manager software CLI. Values that can be used and still guarantee the Tiered Storage Manager operations To guarantee Tiered Storage Manager operations, HP recommends that you specify environment settings and perform operations within the value ranges listed below.
#2 This is the maximum value. If this value is exceeded, an error occurs. The following problems might occur if you operate Tiered Storage Manager software in an environment where one or more values exceed the above values: • The response time during Tiered Storage Manager software operations will greatly increase. • A memory shortage will occur because the amount of memory used by the Tiered Storage Manager server process, GUI process, CLI process, or Web browser will increase.

0 to 9 Hyphen (-) Underscore (_) Period (.) At sign (@) Space character ( ) Non-ASCII characters Reference information regarding migration This section describes the reasons displayed by the GetVolumes command when migrations cannot be performed. This section also describes the conditions that must be met when a migration is performed in which THP pools are specified for the migration target and LUSE volumes are specified for the migration source.
Displayed character string Status of the specified volume Command Device The volume is used as a command device. The volume is one of the following: Continuous Access Asynchronous Status < Continuous Access XP Asynchronous Status > • The volume is part of a Continuous Access Asynchronous pair, and the status is neither PSUS nor PSUE. • The volume is part of a Hitachi TrueCopy Asynchronous for Mainframe pair, and the status is not suspended.
Displayed character string Status of the specified volume Reserved The volume has already been reserved by Device Manager. System Disk The volume is a system drive. The volume is one of the following: • The volume is the P-VOL of a Snapshot pair, its status is PAIR, and the number of generations is 64. XP Snapshot Status • The volume is the P-VOL of a Snapshot pair and its status is not PAIR. • The volume is the V-VOL of a Snapshot pair. • The volume is the POOL of a Snapshot pair.
Displayed character string Status of the specified volume The volume is one of the following: • The volume is part of a Continuous Access Synchronous pair, and the status is either PSUS or PSUE. Continuous Access Synchronous (target) < Continuous Access XP Synchronous (target) > • The volume is part of a Continuous Access Synchronous for Mainframe pair, and the status is suspended. • This applies only to HP P9500 or XP24000/XP20000.
• The number of THP volumes in the migration target pool is less than the maximum value (HP P9500: 63,232; XP24000/XP20000: 8,192). • The maximum over-provisioning percent in the migration target pool must not exceed the warning threshold for the over-provisioning percent and the upper limit for the over-provisioning percent. This condition also applies after migration.
Glossary This glossary defines the special terms used in this document. host group A group of hosts with WWN HBAs that are allowed to issue I/Os to specified volumes. You can specify multiple volumes. Host groups are managed by LUN Manager for the storage. host storage domain A host group. In this manual, host storage domain means the same thing as host group.
parity group A group of physical drives in a RAID configuration in a storage system. parity group avoidance rule This rule does not select, as a migration target parity group, a parity group that contains an LDEV that belongs to a specific migration group. parity group selection rule This is the rule specified when you want to select a migration target after considering the usage status of parity groups.
THP volume A virtual volume that is created from a THP pool or is related to a THP pool. virtual volume A generic term for virtual volumes used in storage functions.
