resumegmir

Parameters

-dev storage_image_ID

(Optional). Specifies the storage image ID, which includes manufacturer, machine type, and serial number. This parameter is required if you do not specify a fully qualified LSS ID or you do not specify a value for the devid variable in your profile file.

Example: IBM.1750-68FA120

-lss LSS_ID

(Required). Specifies the master logical subsystem (LSS) that is to receive the resumegmir command. Accepts a fully qualified LSS ID, which includes the storage image ID, or a shortened version without the storage image ID if the -dev parameter is specified. The shortened version is two hexadecimal digits in the range 00 - 1F (1750 only).

Example of a fully qualified LSS ID: IBM.1750-68FA120/10

Tuning parameters consist of the following three values: -cginterval seconds , -coordinate milliseconds , -drain seconds

Tuning parameters have default values applied to them from the microcode. However, you can choose to change those values. You must designate a value for each of the parameters even if you are changing only one value. For example, if you decide to change only the value on the -cginterval parameter from 0 to 1, your command must include the default values for the other two parameters. Your command would look like the following:

dscli>resumegmir IBM.1750-68FA120/10 
-cginterval 1 -coordinate 50 -drain 30 -session 01 
IBM.1750-68FA120/00:IBM.1750-68FA150/00

-cginterval seconds: Specifies the consistency group interval time, in seconds. This number specifies how long to wait between the formation of consistency groups. If this number is not specified or is set to zero, consistency groups are formed continuously.

The default value is 0. The maximum value is 65 535 seconds.

-coordinate milliseconds: Specifies the maximum coordination interval, in milliseconds. This value indicates the maximum time that Global Mirror processing queues Primary/Host/IO to start forming a consistency group.

The default value is 50 milliseconds. The maximum value is 65 535 milliseconds.

-drain seconds: Specifies the maximum consistency group drain time in seconds and the maximum amount of time that the consistent set of data is allowed to drain to the remote site before failing the current consistency group.

The default drain time is 30 seconds.

-session session_ID

(Required). Specifies the Global Mirror session that is to be started. A session ID is a Global Mirror session number that you assign in the 01 - FF hexadecimal range.

Example: 01

Master_Control_Path_LSS_ID:Subordinate_Control_Path_LSS_ID . . . | -

(Optional). Specifies one or more Global Mirror path associations. A Global Mirror path association consists of two fully qualified LSS IDs. The first is designated as the master resource and the second is the subordinate resource between which a PPRC path has been established. A LSS ID is two hexadecimal characters in the range 00 - 1F (1750 only). You must separate the fully qualified LSS IDs of a Global Mirror association with a colon and no spaces. The master resource must be identical for all relationships.

If you specify the dash (-), this parameter information is automatically supplied. However, you cannot use the dash (-) if you are using the DS CLI interactive mode.

Example of one Global Mirror association with a single subordinate in the configuration: IBM.1750-68FA120/00: IBM.1750-68FA150/00

Example of multiple Global Mirror associations with two subordinates in the configuration: IBM.1750-68FA120/00: IBM.1750-68FA150/00 IBM.1750-68FA120/00: IBM.1750-68FA150/01
