Figure 75 Suspend Pair Window

The Suspend Pair window displays the following settings:

S-VOL Write: Allows you to specify whether hosts can issue read I/O and write I/O to the
secondary data volume after the mirror is split. The default is Disable.

If you select Enable, hosts can issue read I/O and write I/O to the secondary data volume
after you split the mirror.

If you select Disable, hosts cannot issue read I/O and write I/O to the secondary data volume
after you split the mirror.

This parameter takes effect only when the selected volume is a master journal group.

Range: Allows you to specify the split range. This parameter is always set to Group and cannot
be changed.

Suspend Mode: Allows you to specify how to handle update data that are not reflected to the
secondary data volume. The default is Flush.

If you select Flush, update data will be reflected to the secondary data volume when you
split the mirror.

When the secondary storage system receives a request for splitting a mirror, all the journal
data (that is, update data) that the mirror retains will be written to the secondary data
volume. After that, the status of the mirror will change from Suspending to Suspend if the
mirror does not retain any journal data for a certain period of time.

If you select Purge, update data will not be reflected to the secondary data volume when
you split the mirror. If you restore the mirror, the update data will be reflected to the
secondary data volume.
