Procedure: Getting node canister and system information
using the service assistant
Note: Model types 2073-700 are file modules.
v The model description that is shown on the left end cap. The description shows
either Control or Expansion.
Note: The model description shows file module for a file module.
v The number of ports at the rear of the enclosure. Control enclosures have
Ethernet ports, Fibre Channel ports, and USB ports on the canisters. Expansion
enclosures do not have any of these ports.
v The number of LEDs on the power supply units. The power supply units in the
control enclosure have six LEDs. The power supply units in the expansion
enclosure have four LEDs.
Identify the enclosure. An enclosure is identified by its ID and serial number.
Use this procedure to verify the status of objects in your system using the
management GUI. If the status of the object is not online, view the alerts and run
the recommended fix procedures.
Volumes normally show offline because another object is offline. A volume is
offline if one of the MDisks that makes up the storage pool that it is in is offline.
You do not see an alert that relates to the volume. Instead, the alert relates to the
MDisk. Performing the fix procedures for the MDisk enables the volume to go
online.
An overview of the status is displayed under Connectivity in the lower-left corner
of the management GUI window.
Use the following management GUI functions to find a more detailed status:
v Monitoring > System Details
v Monitoring > Manage Device
v Pools > MDisks by Pools
v Volumes > Volumes
v Monitoring > Events and then use the filtering options to display alerts,
messages, or event types.
This procedure explains how to view information about the node canisters and
system using the service assistant.
To obtain the information, connect to and log on to the service assistant using the
starting service assistant procedure. For more information, go to "Accessing the
service assistant" on page 174.
1. Log on to the service assistant.
2. View the information about the node canister that you connected to or the
other node canister in the same enclosure.
Note: If the node canister that you want to see information about is not the
current node, change it to the current node from the home page.
3. Examine the data shown for the current node.
