Modifying the z/OS Global Mirror timeout value using DS CLI

Complete this task to modify the time that a volume in an z/OS Global Mirror session remains in a long-busy condition (the volume is not available) before the session is suspended. This task can be done in the DS8000 only.

You can modify the z/OS^® Global Mirror timeout value, which determines how long any volume in the selected LSS in a z/OS Global Mirror session remains long busy before the session is suspended. The default value is 300 seconds. (The z/OS Global Mirror timeout value is also known as the Extended Remote Copy (XRC) timeout value that is supported on the ESS.)

The long-busy condition occurs because the system data mover cannot copy data when the volume (or z/OS Global Mirror session) is not able to accept additional data. The value of this timeout is associated with a z/OS Global Mirror session when the session is created.

Perform the following step to modify the z/OS Global Mirror timeout value. The example command in this task are shown in two formats. The first format shows the type of information that the command requires. The second format provides the command with values declared for the variables.

Issue the chlcu command to modify the z/OS Global Mirror timeout value. Enter the chlcu command at the dscli command prompt with the following parameters and variables:

dscli>chlcu -dev storage_image_ID -xrcsess timeout LCU_ID

Example

dscli>chlcu -dev IBM.1750-68FA120 -xrcsess 175 00-0F
