LSS copy options

Introduction

Use this page to define copy options for LSSs. An LSS is a group of up to 256 logical volumes that the same disk format (CKD or fixed block) and is identified with a unique ID. You can select copy options for in one LSS or all LSSs in the storage unit. The copy options are applied to all volumes in the LSSs that you selected.

Fields

Storage complex

The list of storage complexes that are available for selection.

Storage unit

The list of storage units that are available for selection.

Select LSS

A list of valid LSSs from which to select. Values include: LSS IDs and All LSSs. If you select All LSSs, the options that you select on this page apply to the LSSs in the selected storage unit.

Concurrent copy timeout

The time, in seconds, that any logical volume in this LSS, in a concurrent copy session stays in a long-busy state (the volume is not available during this time) before suspending the concurrent copy session. The default value is 300 seconds.

Note: This option does not apply to open-system environments.

z/OS^® Global Mirror timeout

The time, in seconds, that any logical volume in an z/OS Global Mirror session stays in a long-busy state before the session is suspended. The long-busy state occurs because the data mover has not copied data when the logical volume (or z/OS Global Mirror session) is no longer able to accept additional data. The default value is 300 seconds.

Note: This option does not apply to open-system environments.

Critical mode enabled

The mode that controls the behavior of the remote mirror and copy pairs that have a source volume in this LSS that is part of a consistency group. With this option enabled, write operations to the source remote mirror and copy volume are prohibited if data cannot be copied to the target volume of the volume pair.

Consistency group timeout enabled

When enabled, a source volume in this LSS in a consistency group that goes into a long-busy state after reporting an error condition. The error condition causes a remote mirror and copy suspension until either a consistency group created operation is performed or until the extended long-busy timeout has elapsed. If the timeout is not enabled, a logical volume on this LSS does not go into a long-busy state after reporting an error that causes remote mirror and copy to be suspended.

Consistency group timeout

The amount of time that data is withheld from updating a source volume of a consistency group when an error occurs. You can optionally change the default time (in seconds) by highlighting and typing over the default. The default value is 120 seconds.
