For example, if you set a service address of 11.22.33.44 for a node canister,
point your browser to 11.22.33.44/service. If you are unable to connect to the
service assistant, see "Problem: Cannot connect to the service assistant" on page
193.
2. Log on to the service assistant using the superuser password.
If you are accessing a new node canister, the default password is passw0rd. If
the node canister is a member of a system or has been a member of a system,
use the password for the superuser password.
If you do not know the current superuser password, reset the password. Go to
"Procedure: Resetting superuser password" on page 197.
Results
Perform the service assistant actions on the correct node canister. If you did not
connect to the node canister that you wanted to work on, access the Change Node
panel from the home page to select a different current node.
Commands are run on the current node. The current node might not be the node
canister that you connected to. The current node identification is shown on the left
at the top of the service assistant screen. The identification includes the enclosure
serial number, the slot location, and if it has one, the node name of the current
node.
Storage system command-line interface
Use the storage system command-line interface (CLI) to manage a storage system
by using the task commands and information commands.
You can also access most of the storage system CLI commands from the Storwize
V7000 Unified CLI that runs in the file system on one of the file modules.
For a full description of the storage system commands and how to start an SSH
command-line session, see the "Command-line interface" topic in the "Reference"
section of the Storwize V7000 Unified Information Center.
When to use the storage system CLI
The storage system CLI is intended for use by advanced users who are confident
at using a command-line interface.
Nearly all of the flexibility that is offered by the CLI is available through the
management GUI. However, the CLI does not provide the fix procedures that are
available in the management GUI. Therefore, use the fix procedures in the
management GUI to resolve the problems. Use the CLI when you require a
configuration setting that is unavailable in the management GUI.
You might also find it useful to create command scripts by using the CLI
commands to monitor for certain conditions or to automate configuration changes
that you make on a regular basis.
Accessing the storage system CLI
Follow the steps that are described in the "Command-line interface" topic in the
"Reference" section of the Storwize V7000 Unified Information Center to initialize
and use a CLI session.
