v
To create a Metro Mirror volume pair between Model types 2107 and a 2105, you
must have added the Add 2105 Copy Services Domain option from the Section
Action drop-down list when you configured your storage complex environment.
v
Ensure that paths are set up between the source and the target LSSs for the
Metro Mirror volume pairs. The paths between the 2105 and the 2107 must be
configured using Fibre Channel Protocol (FCP) ports.
v The storage type of the source and target volumes on the 2107 and 2105
domain must have the same type. That is, if the source volumes are fixed block
volumes, the target volumes must also be fixed block volumes.
v The size of the volumes in the source LSS must be less than or equal to those of
the target LSS.
You can create Metro Mirror relationships using source and target volumes from the
following machine types:
v A 2107 and a 2107
v A 1750 and a 1750
v A 2107 and a 1750
v A 2105 and a 1750
v
A 2105 and a 2107
Note: If the source is a Copy Services 2105 domain, the Metro Mirror task is
performed on the source domain. However, if you perform a
″
Suspend at
target
″
action, the suspension occurs at the target domain.
To create a Metro Mirror pair between a 2107 and a 2105, perform the following
steps. For this task, the source domain is a 2105 Model 800 or 750 and the target
is a 2107.
1. In the navigation, under Copy Services, click Metro Mirror.
2. Select the 2105 Copy Services domain from the list of storage complexes.
This option is enabled if you included a Copy Services domain for the 2105
when you selected Storage Complex from the Section Action drop-down list
under Manage Hardware . All storage complexes that you added when you
configured your environment are included in the drop-down list.
3. Select a storage unit that you will be working with from the Storage unit
drop-down menu.
4. Select a storage image from the Storage image drop-down menu.
5. Select a resource type from the Resource type drop-down menu.
6. Select which resource to view from the Specify (LSS, Volume Group, Host
attachment, Storage type) drop-down menu.
7. Click on Select Action drop-down menu and select Create... and click Go .
8. On the Volume pairing method page, specify one of the following methods by
which to select volume pairs and then click Next.
a. If you click the Automated volume pair assignment , the first selected
source volume is paired automatically with the first selected target volume.
b. If you click Manual volume pair assignment , you must select each
specific target volume for each selected source volume.
9. On the Select source volumes page, select the volumes that you want to
include for the Metro Mirror relationships and click Next . If the resource type is
an LSS, specify which from LSS to select source volumes. Optionally, you can
click the Create paths button to create a new path. You are linked to the page
where you can create a path.
