showlcu

The showlcu command displays the detailed properties of an individual logical control unit (LCU).


>>-showlcu--+-------------------------+--+-LCU_ID-+------------><
            '- -dev--storage_image_ID-'  '-" - "--'

Parameters

-dev storage_image_ID: (Optional). Specifies the storage image ID, which consists of manufacturer, type, and serial number. This parameter is required if you do not specify a fully qualified ID for the logical control unit.; Example: IBM.1750-68FA120
LCU_ID | -: (Required). Displays the properties for the specified logical control unit. The LCU ID is a 2-digit hexadecimal number in the range of (1750 only) 00 - 1F.; Accepts a fully qualified LCU ID, which consists of the storage image ID or a shortened version without the storage image ID, if the -dev parameter is specified.; If you specify the dash (-), this parameter information is automatically supplied.; Example: IBM.1750-68FA120/10

Example

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

The following tables represent the headers that are displayed on the output report that is associated with the showlcu command. A separate example is not shown for the 1750. However, there is one difference between what is displayed on the output report for a 2107 versus a 1750. The 2107 displays a value for xrcsesstimout (XRC session timeout), which is not supported on the 1750.

Invoking the showlcu command

dscli>showlcu -dev IBM.2107-75FA120 10

Report field definitions

ID: Specifies the unique identifier that is assigned to this logical control unit object. It includes the storage image ID and the 2-digit LCU ID 1750 only (00 - 1F).
Group: Specifies the server that manages the logical control unit group. The displayed values are 0 or 1.
Addrgrp: Specifies the address group object that the logical control unit is a member of.
Confgvols: Specifies the number of volumes or the logical devices that are assigned to this LCU ID. This number includes base count key data (ckd) volumes and alias ckd volumes.
Subsys: Specifies the subsystem ID that you assigned to this logical control unit. The range of values that you selected from is 0001 - FFFF.
Conbasetype: Specifies the LCU type that you designated for the logical control unit. If you did not designate a type, the default value of 3990-6 is assigned and displayed.
Pprcconsistgrp: Specifies the assigned PPRC consistency group state setting. If you do not designate enabled, the default value of disabled is assigned.
Xtndlbztimout (secs): Specifies the assigned extended long busy timeout value. If you do not designate a value, the default value of 210 seconds is assigned and displayed.
Ccsesstimout (secs): Specifies the assigned concurrent copy session timeout value. If you do not designate a value, the default value of 300 seconds is assigned and displayed.
Crithvmode: Specifies whether the critical heavy mode for Remote Mirror and Copy operations is in effect. If you do not designate a value, the default value of Disabled is assigned and displayed.
