Accessing the cluster by using SSH

You can issue SSH requests to the cluster to perform administrative tasks. SSH is enabled by default.

Before you begin

About this task

Step

  1. From an administration host, enter the ssh command in one of the following formats:
    • ssh username@hostname_or_IP [command]
    • ssh -l username hostname_or_IP [command]

    If you are using an AD domain user account, you must specify username in the format of domainname\\AD_accountname (with double backslashes after the domain name) or "domainname\AD_accountname" (enclosed in double quotation marks and with a single backslash after the domain name).

    hostname_or_IP is the host name or the IP address of the cluster management LIF or a node management LIF. Using the cluster management LIF is recommended. You can use an IPv4 or IPv6 address.

    command is not required for SSH-interactive sessions.

Examples of SSH requests

The following examples show how the user account named "joe" can issue an SSH request to access a cluster whose cluster management LIF is 10.72.137.28:

$ ssh joe@10.72.137.28 
Password:
cluster1::> cluster show
Node                  Health  Eligibility
--------------------- ------- ------------
node1                 true    true
node2                 true    true
2 entries were displayed.

cluster1::>
 
$ ssh -l joe 10.72.137.28 cluster show
Password:
Node                  Health  Eligibility
--------------------- ------- ------------
node1                 true    true
node2                 true    true
2 entries were displayed.

The following examples show how the user account named "john" from the domain named "DOMAIN1" can issue an SSH request to access a cluster whose cluster management LIF is 10.72.137.28:

$ ssh DOMAIN1\\john@10.72.137.28 
Password:
cluster1::> cluster show
Node                  Health  Eligibility
--------------------- ------- ------------
node1                 true    true
node2                 true    true
2 entries were displayed.

cluster1::> 
$ ssh -l "DOMAIN1\john" 10.72.137.28 cluster show
Password:
Node                  Health  Eligibility
--------------------- ------- ------------
node1                 true    true
node2                 true    true
2 entries were displayed.
