advanced swap operation. The secondary site volume
becomes the secondary volume and the primary site
volume becomes the primary volume.
Ending maintenance on the
primary site work server
Takeover: 1
To switch an application to the secondary site, execute
an advanced swap operation. The secondary site volume
becomes the primary volume, and the primary site
volume becomes the secondary volume. Next, perform
a basic split to suspend the copy pair.
Performing maintenance on the
primary site storage
Takeback: 2
Because application data written while the secondary
site is active is not stored on the volume at the primary
site, first execute a basic resync operation. To switch the
application to the primary site, execute an advanced
swap operation. The secondary site voulme becomes
the secondary volume, and the primary site volume be-
comes the primary volume.
Ending maintenance on the
primary site storage
Takeover: 5
To allow for maintenance on the remote copy line, sus-
pend the remote copy pair by executing a basic split
operation.
Performing maintenance on a

vanced takeover operation. The secondary volume on
the secondary site is changed to a writable Split (SSWS)
status.
Primary site storage failure (no
loss of primary site data)
Takeback: 1
Execute a takeover-recovery (resync) operation to change
the secondary site volume to the primary volume and the
primary site volume to the secondary volume, and copy
the data on the secondary site volume to the primary site
volume. To move the application to the primary site, ex-
ecute an advanced swap operation. The secondary site
volume becomes the secondary volume, and the primary
site volume becomes the primary volume.
