Overview of the `sscs` Command

The sscs command-line interface (CLI) enables you to manage and monitor disk arrays. The CLI can be installed on a local data host or a remote management host.

There are two forms of the CLI:

Local CLI

This is the version used in a CLI-only installation of Sun Storage Common Array Manager, and should be used if you are root user on the local host. This version does not pass commands through the web server and provides better performance by eliminating the need to authenticate the user. There is no guest-only version of the local sscs command, and the login and logout commands aren’t supported.

Directory locations for local CLI:

Solaris: /opt/SUNWstkcam/bin/sscs

Linux: /opt/sun/cam/bin/sscs

Windows: Program Files\Sun\Common Array Manager\bin

Remote CLI

This version is required if you are not on the Sun Storage Common Array Manager management station or if you must authenticate as a non-root user. This version passes all requests through the web server, and is more secure than the Local CLI since all traffic is encrypted.

Directory locations for remote CLI:

Solaris: /opt/se6x20/cli/bin/sscs

Linux: /opt/sun/cam/se6x20/cli/bin/sscs

32 Bit Windows: c:\Program Files\Sun\Common Array Manager\Component\sscs\bin

64 Bit Windows: c:\Program Files (x86)\Sun\Common Array Manager\Component\sscs\bin

Note - When using the remote CLI with Windows, list parameters in commands must be enclosed in double quotes. For example:

sscs list template "F5100-dual-host,J4500-quad-host"

Both CLIs can manage any array that has been registered and added to the Sun Storage Common Array Manager inventory in the same way that the browser interface can manage any array in the inventory. The array type and array management path (in-band, out-of-band, proxy agents) have no limitations with local or remote CLI usage. Both CLIs manage the same arrays with the same command set.

Accessing the CLI Remotely

The local and remote CLIs can be accessed remotely through the full management workstation using:

Terminal session at the management workstation

Navigate to the Local CLI directory to manage the arrays via the proxy agent.

A Remote CLI Client from a remote host

This thin scripting client uses HTTPS to communicate with the management host. Login to the management host and navigate to the Local CLI directory to manage the arrays via the proxy agent.

Telnet session from a remote host

Understanding Command Syntax

Type the sscs command with its options from a terminal command line. You can use only the indicated option or options for that subcommand.

TABLE 1-1 describes the conventions that apply to the subcommands and variables.

TABLE 1-1 Syntax Conventions for `sscs` Commands
Convention	Description
Bold	Text in bold should be typed exactly as shown.
Italic	Text in italics is variable and should be replaced with the name or value used at your site. Multiple variables can be separated by a comma, but not with a space. Example: sscs list volume `TestVOL,fvm13311`
[ ] (square brackets)	Text in square brackets is optional.
\| (vertical bar)	Text separated by a vertical bar is exclusive. Specify only one of the options.
{ } (braces)	Text inside braces is a required argument. Numbers in braces, e.g. {0} and {1}, represent variables in some error messages.
Short and long names	The `sscs` command accepts short or long names for each option. Short name options require a single hyphen (-). Long name options require a double hyphen (--).
Special characters in names	Do not use spaces, commas, colons (:), or the special characters ?,*,!,@,%, or & as a character in any name you specify unless you are prepared to escape them in the shell. Any characters that you enclose within quotation marks are acceptable for names.

TABLE 1-1, Syntax Conventions for sscs Commands, describes the conventions that apply to the subcommands and variables.

Note - Command syntax can vary based upon the array type (e.g., F5100, 6140, etc.) and specific array names as related to installed firmware versions. See TABLE 1-2 for proper usage of the --help command to obtain the correct syntax for an array type or specific array name.

Getting Help with Commands and Their Syntax

Use the --help or -H command to view all available commands, subcommands, and their syntax. TABLE 1-2 describes how to use the --help command. Further help can be found in the man pages, which contain the same command information as found in this document:

For Solaris, see the sscs(1M) man page, located in

/opt/se6x20/cli/man/man1m

For Linux, see the sscs(1M) man page, located in

/opt/sun/cam/se6x20/cli/man/man1m

For Windows, see the doc directory.

TABLE 1-2 How to Use the --help Command
Task	Command Syntax
Display a command list non-specific to an array type.	sscs --help
Display a command list specific to an array type or array name.	sscs -H -a <array-type \| array-name> Command example: sscs --help -a 2510 Sample Command Output: `add` `create` `delete` `disable` `enable` `...` `revive` `service` `snapshoot` `unmap` `unregister`
Display the subcommands available for a command for a specific array type or array name.	sscs <subcommand> -H -a <array-type \| array-name> Command example: sscs list --help -a jbod1 Sample Command Output: `alarm` `array` `device` `...` `storage-system` `template` `userrole`
Display syntax for a command/subcommand pair for a specific array type or array name.	sscs <subcommand> --help -a <array-type \| array-name> <resource-type> Command example: sscs list --help -a j4400 alarm Sample Command Output: `list [-s\|--severity <0\|1\|2\|3>] [-f\|--faultdevtype <2510\|2530\|2540\|j4200\|j4400\|j4500\|F5100\|6120\|6130\|6140\|6540\|6580\|6780\|FLX240\|FLX280\|FLX380\|B6000\|NEM\|...>] [-a\|--advisor] [-S\|--Summary] alarm [string[,string...]]`

TABLE 1-2, How to Use the --help Command, describes the tasks and syntaxes associated with the --help command.

Logging In to the sscs Environment

If you are using the local CLI, no login is required; however, you must have root access in Solaris and Linux or administrator privileges in Windows.

A login is required when you use the remote CLI. To log into the remote CLI, follow these steps:

1. From a terminal window, log in to the management host where sscs resides.

2. Enter the following commands:

# cd CLI_directory

Refer to Overview of the sscs Command for directory information.

# ./sscs login -h cam-hostname -u username

where:

cam-hostname is the management host machine where you installed the software.

username is one of the defined users in the management host software.

3. Enter the password for your sscs user account.

For further details about logging in to the sscs using the remote CLI, see the login command and all of its options, go to login.

Exit Status Codes

Upon command completion, the sscs CLI reports the following exit status codes:

TABLE 1-3 Exit Status Codes
Exit Status Code	Description
0	Successful completion
15	Object not found error
25	Command parsing failure
30	Command validation error
50	Application error
75	System error
100	Nonspecific error

TABLE 1-3, Exit Status Codes, lists the exit status codes and their descriptions.

Using the CLI to Configure Arrays

Once Sun Storage Common Array Manager has been installed, initial configuration can be performed using the CLI. General steps and commands for initial configuration include:

Providing the installation site information using
modify site

Registering with Auto Service Request (ASR) using
register sun-connection

Discovering and registering arrays using
register storage-system

These commands, as well as other commands for configuring storage, are described in detail in this guide.
