FlashSystem/IBM Spectrum Accelerate Metro Mirror - Global Mirror session properties

The properties are displayed on different tabs in the notebook. Use the Session Options tab to set properties that apply to the entire session. Use the H1-H3 Options and H2-H3 Options to set properties that apply to the role pair.

Session Options

Enter the properties for the session.

Description

Type the description for this session.

H1-H3 Options and H2-H3 Options

Enter the properties for the role pair.

Recovery point objective threshold (seconds)

Type the number of seconds that you want to set for the recovery point objective (RPO) threshold for the role pair.

If the Spectrum Accelerate system determines that the RPO is greater than this threshold value, an alert is generated and the session status changes to Severe. You can specify an RPO in the range of 30 - 86400 seconds. The default is 90 seconds.

Synchronization schedule (HH:MM:SS)

Select an interval to create a synchronization schedule. The schedule is used to form consistency groups. The Spectrum Accelerate system attempts to form consistent points of data by taking automatic snapshots of the volumes in the session at this interval. The default is the min_interval schedule defined on the hardware.

If you select Never, synchronization is not scheduled and the Spectrum Accelerate system does not create consistency groups. When the Spectrum Accelerate system determines that the RPO threshold is exceeded, the session state becomes Severe.
