lssu

The lssu command displays a list of storage units in a storage complex. You can use this command to look at the status and other properties of each storage unit in the list.

Parameters

-s: (Optional) Displays storage unit IDs. You cannot use the -l and the -s parameters together.
-l: (Optional) Displays default output and remote mode with scheduled power-on and power-off times, and the storage unit description. You cannot use the -l and the -s parameters together.
-power on | off: (Optional) Displays only the storage units in the specified power state.
storage_unit_ID . . . | -: (Optional) Displays storage units with the specified storage unit IDs. A storage unit ID includes manufacturer, type, and serial number. You must separate multiple IDs with a space between each ID.
Note: You cannot specify ID ranges.; If you specify the dash (-), this parameter information is automatically supplied.

Example

For this command and all other DS CLI list commands, the results are shown in table format to provide clarity. The actual reports do not display as tables.

The following table represents the headers that are displayed on the output report that is associated with the lssu command using the -l parameter. A separate example is not shown for the 1750 because the information is the same for the 2107 and 1750. The only difference is the value input for the storage_unit_ID parameter.

Invoking the lssu command

dscli>lssu -l
