You can convert Global Copy volume
pairs to Metro Mirror (synchronous)
volume pairs.
Before you begin
Before you begin, ensure that license for the Remote Mirror
and Copy feature is activated.
Mirroring connectivity (previously known
as paths) is required between the source and the target LSS storage
units for the volume pairs.
About this task
There are two common situations when you would convert a
Global Copy volume
pair to a
Metro Mirror volume
pair:
- You used Global Copy to
complete the bulk transfer of data in the creation of many copy pairs,
and you now want to convert some or all of those pairs to Metro Mirror mode.
- You have Global Copy copy
pairs for which you want to make FlashCopy® backups
on the remote site. You convert the pairs temporarily to Metro Mirror mode to obtain a point-in-time consistent
copy.
If you created a Global Copy volume
pair where the source volume was associated with a 2107/242x storage
unit and the target volume was from ESS 2105 Model 800 or 750, you
can convert that volume pair to Metro Mirror.
Procedure
Complete the following steps from the DS Storage Manager to
convert a Global Copy relationship
to a Metro Mirror synchronous
relationship:

page is displayed.
- Select one or more Global Copy volume pairs and select Convert to Metro Mirror from
the Action menu.
- In the Convert Global
Copy to Metro Mirror window, confirm the selected relationships
that you want to convert to Metro Mirror,
then, click Convert.
