Complete this task to convert Global Copy volume
pairs to synchronous (Metro Mirror volume
pairs).
Before you begin, ensure that license for the remote mirror and copy
feature is activated. Paths are required between the source and the target
LSS storage units for the volume pairs.
There are two common situations when you would convert a
Global Copy volume pair to a
Metro Mirror volume
pair:
- You have 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 synchronous mode in order to obtain a point-in-time
consistent copy.
If you created a Global Copy volume
pair where the source volume was associated with a 1750 storage
unit and the target volume was from ESS 2105 Model 800 or 750, you can convert
that volume pair to synchronous. All domains that you added when you configured
your environment are included in the Storage Complex drop-down list. The volumes
involved in relationships can be source or target volumes.
Perform
the following steps to convert a Global Copy relationship
to a Metro Mirror synchronous
relationship:
- In the navigation, select . A page containing volume pairs displays from which you can select.
- Select one or more volume pairs and select Convert to synchronous from
the Select Action drop-down box. Then,
click Go.
- On the table that displays, confirm which selected relationships
the volume tracks will be converted to synchronous, Then, click OK.
