Storwize V7000 Unified: Problem Determination Guide Version
To access a node canister directly, it is normally easier to use the service assistant
with its graphical interface and extensive help facilities.
Accessing the service 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.
Use a USB key to initialize a system and also to help service the node canisters in
a control enclosure.
The initialization tool is a Windows application. Use the initialization tool to set up
the USB key to perform the most common tasks.
When a USB key is inserted into one of the USB ports on a node canister in a
control enclosure, the node canister searches for a control file on the USB key and
runs the command that is specified in the file. When the command completes, the
command results and node status information are written to the USB key.
When to use the USB key
The USB key is normally used to initialize the configuration after installing a new
system.
Using the USB key is required in the following situations:
v When you cannot connect to a node canister in a control enclosure using the
service assistant and you want to see the status of the node.
v When you do not know, or cannot use, the service IP address for the node
canister in the control enclosure and must set the address.
v When you have forgotten the superuser password and must reset the password.
Using a USB key
Use any USB key that is formatted with FAT32, EXT2, or EXT3 file systems on its
first partition.
When a USB key is plugged into a node canister, the node canister software
searches for a text file named satask.txt in the root directory. If the software finds
the file, it attempts to run a command that is specified in the file. When the
command completes, a file called satask_result.html is written to the root
directory of the USB key. If this file does not exist, it is created. If it exists, the data
is inserted at the start of the file. The file contains the details and results of the
command that was run and the status and the configuration information from the
node canister. The status and configuration information matches the detail that is
shown on the service assistant home page panels.
The satask.txt file can be created on any workstation by using a text editor. If a
Microsoft Windows workstation is being used, the initialization tool can be used to
create the commands that are most often used.
The fault LED on the node canister flashes when the USB service action is being
performed. When the fault LED stops flashing, it is safe to remove the USB key.
The USB key can then be plugged into a workstation and the satask_result.html
file viewed in a web browser.
