Abstract

This following guide contains information for installing and using the Red Hat Storage Console Command Line Shell.
Red Hat Storage Console Command Line Interface is under Technology Preview. The features are not fully supported under Red Hat subscription level agreements (SLAs), may not be functionally complete, and are not intended for production use. However, these features provide early access to upcoming product innovations, enabling customers to test functionality and provide feedback during the development process. As Red Hat considers making future iterations of Technology Preview features generally available, we will provide commercially reasonable efforts to resolve any reported issues that customers experience when using these features.

Chapter 1. About the Command Line Interface

Introduction to the Command Line Interface

The Red Hat Storage Console features a command line interface (CLI). This CLI provides users with a means to connect to Red Hat Storage Console other than the standard web interface. The CLI also contains a scripting system that helps system administrators perform periodic maintenance or repetitive tasks in their environment with client machines.

Important

Red Hat Storage Console Command Line Interface is under Technology Preview. Hence, its features are not fully supported under Red Hat subscription level agreements (SLAs), may not be functionally complete, and are not intended for production use. However, these features provide early access to upcoming product innovations, enabling customers to test functionality and provide feedback during the development process. As Red Hat considers making future iterations of Technology Preview features generally available, we will provide commercially reasonable efforts to resolve any reported issues that customers experience when using these features.

Chapter 2. Using the CLI

2.1. Installing the CLI

Procedure 2.1. Installing the Red Hat Storage Console CLI on a Client Machine

  1. Log into the client machine as the root user.
  2. Subscribe to the Red Hat Storage Console Channels:
    Red Hat Satellite Server instructions
       
    # rhn_register 
    # rhn-channel --add --channel=rhel-x86_64-server-6-rhs-rhsc-3
    Red Hat Content Delivery Network instructions:
       
    # subscription-manager list --available | grep -A8 "Red Hat Storage Console"
    # subscription-manager subscribe --pool=POOLID
    # yum-config-manager --enablerepo=rhsc-3-for-rhel-6-server-rpms

    Note

    See Red Hat Storage Console Release Notes for channel names specific to your system.
  3. Install the CLI package and dependencies:
    # yum install rhsc-cli
    

2.2. TLS/SSL Certification

The Red Hat Storage Console API requires Hypertext Transfer Protocol Secure (HTTPS) for secure interaction with client software such as the Manager's SDK and CLI components. This involves obtaining a certificate from your Red Hat Storage Console server and importing it into the certificate store of your client.

Important

Obtain your certificate from the Red Hat Storage Console using a secure network connection.

Procedure 2.2. Obtaining a Certificate

This process helps a user obtain a certificate from the Red Hat Storage Console and transfer it to the client machine. A user achieves this using one of three methods:
  1. Method 1 - Use a command line tool to download the certificate from the server. Examples of command line tools include cURL and Wget. Both are available on multiple platforms.
    1. If using cURL:
      curl -o rhsc.cer http://[rhsc-server]/ca.crt
    2. If using Wget:
      wget -O rhsc.cer http://[rhsc-server]/ca.crt
  2. Method 2 - Use a web browser to navigate to the certificate located at:
    http://[rhsc-server]/ca.crt
    Depending on the browser, the certificate either downloads or imports into the browser's keystore.
    1. If the browser downloads the certificate: save the file as rhsc.cer.
      If the browser imports the certificate: export it from the browser's certification options and save it as rhsc.cer.
Each of the above three methods creates a certificate file named rhsc.cer on your client machine. An API user imports this file into the certificate store of the client.

2.3. Running the CLI

Start the CLI application with the following command:
# rhsc-shell
The rhsc-shell application is an interactive shell for Red Hat Storage Console.
Users connect automatically to Red Hat Storage Console using the following additional options.
# rhsc-shell -c -l "https://[server]/api" -P [port] -u "[user@domain]" -A "[certificate]"
Replace the following values:
  • server - The hostname or IP address of the Red Hat Storage Console. The CLI connects to the Red Hat Storage Console via the REST API.
  • user@domain - The user name and directory service domain for the user logging into Red Hat Storage Console.
  • certificate - The path of the Certificate Authority file.
The shell will prompt you for the password, and, if not already provided, the username and the URL for the Red Hat Storage Console.

Note

The certificate is the only mandatory option; the other options used in this example will be prompted by the shell. Also, instead of specifying the certificate, you can use the --insecure option to connect without a certificate. However, this is not recommended as it may allow man-in-the-middle (MITM) attackers to spoof the identity of the server.

Table 2.1. Options for rhsc-shell

Command Options Description
-h, --help Show help for rhsc-shell.
-d, --debug Enables debugging.
-l URL, --url=URL Specifies the API entry point URL.
-u USERNAME, --username=USERNAME Connect as this user.
-K KEY_FILE, --key-file=KEY_FILE Specify key file.
-C CERT_FILE, --cert-file=CERT_FILE Specify certificate file.
-A CA_FILE, --ca-file=CA_FILE Specify server Certificate Authority file.
-I, --insecure Allow the CLI to connect via SSL without certification. This option should be used with caution, as it may allow man-in-the-middle (MITM) attackers to spoof the identity of the server.
-F, --filter
Enable filtering based upon user permissions.
-P PORT, --port=PORT Specify port.
-T TIMEOUT, --timeout=TIMEOUT Specify timeout.
-c, --connect Automatically connect.
-f FILE, --file=FILE
Read commands from FILE instead of stdin.

Note

Although users can use the --file option to call a file that includes their password information, this practice is not recommended for security reasons. Users with a non-interactive shell can connect to the Red Hat Storage Console from within the shell, where the --password option can be used.

2.4. Interacting with the CLI

The CLI is an interactive shell for controlling your Red Hat Storage Console from the command line. Type the required command and any additional parameters.

Example 2.1. Entering a shell command

[RHSC shell (connected)]# show cluster --name desktop_clusters
To support the construction of command and parameter combinations, the CLI includes the functionality to list and automatically complete commands and parameters by pressing the TAB key twice, similar to the bash shell.

Example 2.2. Listing and automatic completion of commands and parameters

Press TAB twice at a blank prompt to list all available commands.
[RHSC shell (connected)]# TAB TAB
EOF       connect       exit       info       shell
action    console       file       list       show
add       disconnect    help       ping       status
clear     echo          history    remove     update
Choose a command and press TAB twice to view the next set of available parameters for the command. For the show command, this lists all resources.
show TAB TAB
brick      glustervolume      network      role
cluster    group              nic          statistic
domain     hook               permission   tag
event      host               permit       user
Pressing TAB twice also completes commands and parameters.
[RHSC shell (connected)]# show cluster TAB TAB
id         name           
[RHSC shell (connected)]# show cluster naTAB TAB
[RHSC shell (connected)]# show cluster --name
Note that pressing TAB twice also automatically formats na to the --name parameter, including the prefix. If the incomplete parameter matches multiple parameters, pressing TAB twice lists all those parameters.
The CLI provides functions for running Linux commands using either the shell command or the bang (!) character.

Example 2.3. Running Linux shell commands

Use the shell command:
[RHSC shell (connected)]# shell ls -la
Or use the bang (!) character:
[RHSC shell (connected)]# !ls -la
Similar to the Linux shell, the CLI can pipe data to other commands and sources.

Example 2.4. Piping CLI commands

Pipe CLI data to a Linux shell command:
[RHSC shell (connected)]# list clusters --show-all | grep "Example"
name                      : Example1
name                      : Example2
name                      : ExampleEngineering
description               : An Example description
name                      : BestExampleCluster
Pipe CLI data to a file:
[RHSC shell (connected)]# list clusters --show-all > cluster_List.txt
The CLI also contains an online help system to provide descriptions and syntax for each command via the help command.

Example 2.5. Using online help for the show command

[RHSC shell (connected)]# help show

2.5. Collections

Some command parameters require a collection. A collection is a set of sub-parameter data. Collections are defined using the following syntax.
[RHSC shell (connected)]# command --param-collection {subparam1=value1;subparam2=value2;subparam3=value3;...},{subparam1=value1;subparam2=value2;subparam3=value3;...},...
Sub-parameters for collections are listed after resource parameter listings on each resource page.

Chapter 5. CLI Queries

5.1. Query Syntax

The CLI list command uses the --query attribute to perform server-side queries, which uses the same format as Red Hat Storage Console search query language:

Table 5.1. 

Collections Criteria Result
hosts host.status=up Displays a list of all hosts running clusters that are up.
events severity>normal sortby time Displays the list of all events with severity higher than normal and sorted by the time element values.
events severity>normal sortby time desc Displays the list of all events with severity higher than normal and sorted by the time element values in descending order.

5.2. Wildcards

Search queries substitute part of a value with an asterisk as a wildcard.

Example 5.1. Wildcard search query for name=cluster*

[RHSC shell (connected)]# list cluster --query "name=cluster*"
This query would result in all clusters with names beginning with cluster, such as cluster1, cluster2, clustera or cluster-webserver.

Example 5.2. Wildcard search query for name=c*1

[RHSC shell (connected)]# list cluster --query "name=c*1"
This query would result in all clusters with names beginning with c and ending with 1, such as ccluster1, cclusters1 or cclusterszoneone1.
