Procedure using the Change Pair Status Wizard Scenario
Takeover: 3
To switch an application to the secondary site, execute
an advanced swap operation. The volume at the second-
ary site becomes the primary volume, and the volume
at the primary site becomes the secondary volume. Per-
form work on the secondary site while work server
maintenance is carried out on the primary site.
Performing maintenance on the
primary site work server
Takeback: 3
To switch an application to the primary site, execute an
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 volume 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
remote copy line
Takeback: 5
To return the remote copy pair to a normal pair status,
execute a basic resync operation on the remote copy
pair.
Ending maintenance on a re-
mote copy pair line
Takeover: 5
To allow maintenance on the remote site, suspend the
remote copy pair by executing a basic split operation. Performing maintenance on a
remote site
Takeback: 5
When you have finished maintenance on the remote
site, return the remote copy pair to normal pair status
by executing a basic resync operation.
Ending maintenance on a re-
mote site
Takeover: 3
To switch work to the secondary site, execute an ad-
vanced swap operation. The secondary site volume be-
comes the primary volume, and the primary site volume
becomes the secondary volume.
Work server failure
Takeback: 3
To switch work to the primary site, execute an advanced
swap operation. The secondary site volume becomes
the secondary volume, and the primary site volume be-
comes the primary volume.
