About The Command Line Interface

This guide is intended for system administrators, developers, and engineers who need to use the command line interface (CLI) tool and its associated commands and script files. Selected CLI commands perform functions that can also be accessed from the Modular Disk (MD) Storage Manager, which is the graphical user interface (GUI) to the storage array. See the Administrator's Guide, which describes the Storage Manager software that is used to create and manage multiple storage arrays. For additional information, see the hardware and software manuals that shipped with your system.

NOTE: Always check for updates on dell.com/support and read the updates first because they often supersede information in other documents.

NOTE: CLI commands do not have interactive warnings for destructive commands.

CLI is a software tool that enables storage array installers, developers, and engineers to configure and monitor storage arrays. Using the command line interface, you can issue commands from an operating system prompt, such as the Microsoft Windows command prompt (C:\) or a Linux operating system terminal.

Each command performs a specific action for managing a storage array or returning information about the status of a storage array. You can enter individual commands, or run script files when you need to perform operations more than once (such as installing the same configuration on several storage arrays). A script file can be loaded and run from the command line interface. You can also run commands in an interactive mode. Interactive mode enables you to connect to a specific storage array and rapidly enter a command, determine the effect on the storage array, and then enter a new command.

The command line interface gives you direct access to a script engine utility in the Dell PowerVault Modular Disk Storage Manager software (MD Storage Manager). The script engine reads the commands, or runs a script file, from the command line and performs the operations instructed by the commands.

You can use the command line interface to perform the following functions:

• Directly access the script engine and run commands in interactive mode or using a script file.

• Create script command batch files to be run on multiple storage arrays when you need to install the

same configuration on different storage arrays.

• Run script commands on a storage array directly connected to a host, a storage array connected to a

host by an Ethernet, or a combination of both.

• Display configuration information about the storage arrays.

• Add storage arrays to and remove storage arrays from the management domain.

• Perform automatic discovery of all storage arrays attached to the local subnet.

• Add or delete Simple Network Management Protocol (SNMP) trap destinations and e-mail alert

notifications.

• Specify the mail server and sender e-mail address or Simple Mail Transport Protocol (SMTP) server for

alert notifications.

• Direct the output to a standard command line display or to a named file.

How To Use The Command Line Interface

Using the CLI commands, you can access the script engine, specify which storage array receives the script commands, and set operation environment parameters.

A CLI command consists of the following elements:

• The term SMcli

• Storage array identifier

• Parameters

• Script commands

The following syntax is the general form of a CLI command:

SMcli storageArray parameters script-commands;

where,

SMcli invokes the command line interface.

storageArray is the host name or IP address of the storage array.

parameters are the CLI parameters that define the environment and purpose of the command.

script-commands are the commands or name of the script file containing the script commands.

The script commands are the storage array configuration commands. About The Script Commands presents an overview of the script commands. Script commands provide definitions, syntax, and parameters for the script commands.

Usage Notes

If you enter SMcli and a storage array name but do not specify CLI parameters, script commands, or a script file, the command line interface runs in interactive mode. Interactive mode enables you to run individual commands without prefixing the commands with SMcli. You can enter a single command, view the results, and enter the next command without typing the complete SMcli string. Interactive mode is useful for determining configuration errors and quickly testing configuration changes.

If you enter SMcli without any parameters or with an incorrect parameter, the script engine returns usage information.

NOTE: The SMcli command is installed under the client directory of the selected path during a management station install of the MD Storage Manager software.

NOTE: The SMcli command should be a component of the system environment command path.

CLI Commands

This section lists the CLI commands you can use to perform the following functions:

• Identify storage arrays

• Set passwords

• Add storage arrays

• Specify communication parameters

• Enter individual script configuration commands

• Specify a file containing script configuration commands

The following are general forms of the CLI commands, showing the parameters and terminals used in each command. The table below lists definitions for the parameters shown in the CLI commands.

Command Line Parameters

Table 2. Command Line Parameters

Parameter Definition

host‑name-or-IP-address

-A

-a

Specify either the host name or the Internet Protocol (IP) address of an in-band managed storage array (IPv4 or IPv6) or an out-of-band managed storage array (IPv4 or IPv6).

• If you manage a storage array by using a host connected directly to the storage array (in‑band storage management), you must use the -n parameter if more than one storage array is connected to the host.

• If you manage a storage array through an Ethernet connection (out-of-band storage management), you must specify the host‑name‑or‑IP‑address of the redundant array of independent disks (RAID) controller modules.

• If you have previously configured a storage array in the graphical user interface (GUI) of the MD Storage Manager, you can specify the storage array by its user‑supplied name by using the -n parameter.

Use to add a storage array to the configuration files. If you do not follow the -A parameter with a host‑name‑or‑IP‑address, automatic discovery scans the local subnet for storage arrays.

Use to add an SNMP trap destination or an e-mail address alert destination.

• When adding an SNMP trap destination, the SNMP community is automatically defined as the community name for the trap and the host is the IP address or Domain Name Server (DNS) host name of the system to which the trap should be sent.

• When adding an e-mail address for an alert destination, the email-address is the e-mail address to which to send the alert message.

Parameter Definition

-c

-d

-e

-F (uppercase)

-f (lowercase)

Use to indicate that you are entering one or more script commands to run on the specified storage array. Terminate each command by using a semicolon (;).

You cannot place more than one -c parameter on the same command line. You can include more than one script command after the -c parameter.

Use to display the contents of the script configuration file.

Use to disable syntax checking when executing the current CLI command.

Use to specify the e-mail address from which all alerts will be sent.

Use to specify a file name containing script commands intended to run on the specified storage array.

This parameter is similar to the -c parameter in that both are intended for running script commands. The -c parameter allows you to execute individual script commands. The -f

(lowercase)

script commands contained in a file.

parameter allows you to execute

-g

NOTE: By default, any errors encountered when running the script commands in a file are ignored, and the file continues to run. To override this behavior, use the set session errorAction=stop command in the script file.

Use to specify an ASCII file that contains e-mail sender contact information to include in all e-mail alert notifications. The CLI assumes the ASCII file is text only, without delimiters or any expected format. A typical file contains the following information:

• Name

• Title

• Company

• Phone

• Pager

NOTE: You can use any file name that your operating system supports. You must not use userdata.txt. Some operating systems reserve userdata.txt for system information.

Parameter Definition

-h

-I

-i

-m

-n

Use with the -a and -x parameters to specify the host name that is running the SNMP agent to which the storage array is connected.

Use to specify the type of information to be included in the e-mail alert notifications. The following are valid information arguments:

• eventOnly— Only event information is included in the e-mail.

• profile— Event and array profile information is included in the e-mail.

• supportBundle— Event and support bundle information is included in the e-mail.

NOTE: You can enter only one information argument each time you execute the command. If you want all of the information, you must run the command three times.

Use with the -d parameter to display the IP address of the known storage arrays.

Use to specify the host name or IP address of the e-mail server from which to send e-mail alert notifications.

Use to specify the name of the storage array on which to run the script commands. This name is optional when you use host‑name-or-IP- address; however, if you are using the in-band method for managing the storage array, you must use the array is connected to the host at the specified address. The storage array name is required when host‑name-or-IP-address is not used; however, the name of the storage array configured for use in the MD Storage Manager GUI (that is, listed in the configuration file) must not be a duplicate name of any other configured storage array.

-n parameter if more than one storage

-o

-p

Use with the -c or -f parameter to specify a file name for all output text that is a result of running the script commands.

Use to specify the password for the storage array on which to run commands. A password is not necessary under the following conditions:

• A password has not been set on the storage array.

• The password is specified in a script file that is running.

Parameter Definition

• The storage array password is specified by using the -c parameter and the set session

password=password command.

-q

-r

Use to specify how frequently to include additional profile or support bundle information in the e-mail alert notifications. An e-mail alert notification that contains at least the basic event information is always generated for every critical event. If you set the-I parameter to eventOnly, the only valid argument for -q is everyEvent. If you set the-I parameter to either profile or supportBundle, this information is included with the e-mails with the frequency specified by the-q parameter.

Valid frequency arguments are:

• everyEvent— Information is returned with every e-mail alert notification.

• 2— Information is returned no more than once every two hours.

• 4— Information is returned no more than once every four hours.

• 8— Information is returned no more than once every eight hours.

• 12— Information is returned no more than once every 12 hours.

• 24— Information is returned no more than once every 24 hours.

Use with the -a or -x parameter to specify the name of a management station. The name of a management station can be either direct_sa (outof-band storage array) or host_sa (in-band storage arrays [host-agent]). The -r parameter enables you to set or change the alert notifications for all storage arrays under each management station.

-S (uppercase)

-s (lowercase)

Use to suppress the informational messages describing command progress that appear when running script commands. (Suppressing informational messages is also called silent mode.) This parameter suppresses the following messages:

• Performance syntax check

• Syntax check complete

• Executing script

• Script execution complete

• SMcli completed successfully

Use with the -d parameter to display the alert settings in the configuration file.

Parameter Definition

-v

-X (uppercase)

-x (lowercase)

Use with the -d parameter to display the current global status of the known devices in the storage array configuration file. (The configuration file lists all of the devices in a storage array configuration and the relationship between the devices. Use the configuration file to reconstruct a storage array).

Use to delete a storage array from the configuration file. (The configuration file lists all of the devices in a storage array configuration and the relationship between the devices. Use the configuration file to reconstruct a storage array).

Use to remove an SNMP trap destination or an email address alert destination. The community is the SNMP community name for the trap, and the host is the IP address or DNS host name of the system to which you want the trap sent.

Use this parameter to display usage information about the CLI commands.

Formatting Considerations

Quotation marks (" ") used as part of a name or label require special consideration when you run the CLI and script commands on a Microsoft Windows operating system. The following explains the use of quotation marks in names while running CLI and script commands on Windows.

When quotation marks (" ") are part of an argument, you must insert a backslash (\) before each quotation mark character unless you are in interactive mode. For example:

-c "set storageArray userLabel=\"Engineering\";"

where, Engineering is the storage array name.

You cannot use quotation marks (" ") as part of a character string (also called string literal) within a script command. For example, you cannot enter the following string to set the storage array name to "Finance"Array:

-c "set storageArray userLabel= \"\"Finance\"Array\";"

On a Linux operating system, the delimiters around names or labels are single quotation marks (‘ ’). The Linux versions of the previous examples are:

-c ‘set storageArray userLabel="Engineering";’

Detailed Error Reporting

Error data collected from an error encountered by the CLI is written to a file. Detailed error reporting under the CLI works as follows:

• If the CLI must abnormally end execution or abort script command execution, error data is collected and saved before the CLI aborts.

• The CLI automatically saves the error data by writing the data to a file with a standard name.

• The CLI does not have any provisions to avoid overwriting an existing version of the file containing error data.

For error processing, errors appear as two types:

• Parameter or syntax errors you might enter

• Exceptions that occur as a result of an operational error

When the CLI encounters either type of error, it writes information describing the error directly to the command line and sets a return code. Depending on the return code, the CLI might also write additional information about which parameter caused the error. The CLI also writes information about what command syntax was expected to help you identify any syntax errors you might have entered.

When an exception occurs while executing a command, the CLI automatically saves the error information to a file named excprpt.txt. The CLI attempts to place excprpt.txt in the directory specified by the system property devmgr.datadir, which by default is the "client/data" directory under the main installation directory in Windows and the /var/opt/SM directory in Linux. If for any reason the CLI cannot place the file in the devmgr.datadir-specified directory, the CLI saves the excprpt.txt file in the same directory from which the CLI is running. You cannot change the file name or location. The excprpt.txt file is overwritten every time an exception occurs. To save the information in the excprpt.txt file, you must copy the information to a new file or directory.

Exit Status

After you run a CLI command or a CLI and script command, status is displayed that indicates the success of the operation defined by the command. The status values are shown in the following table.

Table 3. Exit Status

Status Value Meaning

0 The command terminated without an error.

1 The command terminated with an error. Error information is also

Usage Examples

The following examples show how to enter CLI commands on a command line. The examples show the syntax, form, and in some examples, script commands. Examples are shown for both Windows and Linux operating systems. The usage for the -c parameter varies depending on your operating system. On Windows operating systems, put quotation marks (" ") around the script command following the -c parameter. On Linux operating systems, put single quotation marks (‘ ’) around the script command following the -c parameter.

NOTE: See Script Commands for descriptions of the script commands used in the following examples.

This example shows how to change the name of a storage array. The original name of the storage array is Payroll_Array. The new name is Finance_Array.

Windows:

SMcli -n "Payroll_Array" -c "set storageArray userLabel=\"Finance_Array\";"

Linux:

SMcli -n ‘Payroll_Array’ -c ‘set storageArray userLabel="Finance_Array";’

This example shows how to delete an existing virtual disk and create a new virtual disk on a storage array. The existing virtual disk name is Stocks_<_Bonds. The new virtual disk name is Finance. The RAID controller module host names are finance1 and finance2. The storage array is protected and requires the password TestArray.

Windows:

SMcli finance1 finance2 -c "set session password= \"TestArray\"; delete virtualDisk [\"Stocks_<_Bonds\"];create virtualDisk physicalDiskCount[3] raidLevel=5 capacity=10 GB userLabel=\"Finance\"; show storageArray healthStatus;"

Linux:

SMcli finance1 finance2 -c ‘set session password= delete virtualDisk ["Stocks_<_Bonds"]; create virtualDisk physicalDiskCount[3] raidLevel=5 capacity=10 GB userLabel="Finance"; show storageArray healthStatus;’

This example shows how to run commands in a script file named scriptfile.scr on a storage array named Example. The -e parameter runs the file without checking syntax. Executing an SMcli command without checking syntax enables the file to run more quickly; however, the correctly if the syntax is incorrect.

SMcli -n Example -f scriptfile.scr -e

SMcli command may not execute

This example shows how to run commands in a script file named scriptfile.scr on a storage array named Example. In this example, the storage array is protected by the password My_Array. Output, as a result of commands in the script file, goes to file output.txt.

Windows:

SMcli -n Example -f scriptfile.scr -p "My_Array" - o output.txt

Linux:

SMcli -n Example -f scriptfile.scr -p ‘My_Array’ - o output.txt

This example shows how to display all storage arrays that are currently discovered in the current configuration. The command in this example returns the host name of each storage array.

SMcli -d

If you want to know the IP address of each storage array in the configuration, add the -i parameter to the command.

SMcli -d -i

About The Script Commands

You can use the script commands to configure and manage a storage array. The script commands are distinct from the command line interface (CLI) commands; however, you enter the script commands using the command line interface. You can enter individual script commands, or run a file of script commands. When entering an individual script command, include it as part of a CLI command. When running a file of script commands, include the file name as part of a CLI command. The script commands are processed by a script engine that performs the following functions:

• Verifies command syntax

• Interprets the commands

• Converts the commands to the appropriate protocol-compliant commands, which is, in turn, run by the RAID controller module

• Passes the commands to the storage array

At the storage array, the redundant array of independent disks (RAID) controller modules in the storage array runs the script commands.

The script engine and script commands support the storage array configuration and management operations listed in the following table.

Table 4. Configuration and Management Operations

Operation Activities

Virtual disk, disk group configuration Creating, deleting, and setting priority; labeling;

setting physical disk composition when creating virtual disks; setting segment size; and setting media scan control

Physical disk configuration Configuring the hot spare

RAID controller module configuration Defining virtual disk ownership, changing mode

settings, defining network settings, and setting host port IDs

General storage array configuration Resetting a configuration to defaults, labeling,

checking the health status, setting the time of day, clearing the Major Event Log, and setting the media scan rate

NVSRAM configuration Downloading and modifying the user configuration

Product identification Retrieving the enclosure profile display data

Battery management Setting the battery installation date

Operation Activities

Firmware management Downloading RAID controller module, enclosure

management module (EMM), and physical disk firmware

Script Command Structure

All script commands have the following structure:

command operand-data {statement-data}

where, command identifies the action to be performed, operand-data represents the storage array component to configure or manage (such as a RAID controller module, physical disk, or disk group), and statement-data is what you want to do to the component (such as, specifying the RAID level or availability of a disk group).

The general form of the syntax for operand-data is as follows:

(object-type | allobject-types | [qualifier] (object-type [identifier] {object-type [identifier]} | object-types [identifier-list]))

An operand-data object can be identified four ways:

• The object types and object qualifiers

• The all parameter

• Brackets

• A list of identifiers

NOTE: You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Command names can have a maximum of 30 characters. If you exceed the maximum character limit, replace square brackets ([ ]) with angle brackets (< >) to overcome this limitation.

Use an object type when the command is not referencing a specific object. The all parameter means all objects of the specified type in the storage array (for example,

To perform a command on a specific object, use brackets to identify the object (for example,

virtualDisk[engineering]). Specify a subset of objects with a list of identifiers in brackets (for example, virtualDisks[sales engineering marketing]). In a list of identifiers, use a blank space as the delimiter. A

qualifier is necessary if you want to include additional information to describe the objects.

The following table lists the object type and identifiers associated with the object types.
