Viewing properties for one logical control unit

Complete this task to view the detailed properties of one logical control unit (LCU) that is associated with a storage unit using DS CLI commands.

An LCU represents a logical subsystem for zSeries hosts.

The DS6000 has a 16 384 volume address space that is partitioned into 64 logical subsystem (LSS) units, where each LSS contains 256 logical volume numbers. The 64 LSS units are assigned to one of 4 address groups, where each address group contains 16 LSSs, or 4096 volume addresses. All of the LSSs in one address group must be of the same type (CKD or fixed block).

Because you can modify some of the properties of an LCU, there might times when you want to examine the associated properties. The showlcu command allows you to view the properties of a single LCU.

Perform the following step to view the properties of a single LCU:

Issue the showlcu command to view a report that displays the properties of a single LCU. Enter the showlcu command at the dscli command prompt with the following parameters and variables:

dscli>showlcu -dev storage_image_ID LCU_ID

Note: The LCU ID is a 2-digit hexadecimal number in the range of 00 - 1F.
