Changing Remote Replication Parameters To modify the parameters of a replicated pair, such as the synchronization priority, resynchronization method and write mode, perform these steps: 1 Click Change Replication Parameters. 2 Modify the dialog box to match your requirements for the replicated pair. Removing Replicated Pairs Removing a replicated pair breaks the replication association between the virtual disk at the primary site and the virtual disk at the remote site. After the operation completes, the replication status between the virtual disks is lost. For replication to be re-established, a full resynchronization must occur. Mapping a Virtual Disk After creating new virtual disks, use the Mappings tab to present the virtual disks to the ESX/ESXi host for use. From this view, you can manage hosts, host groups and virtual disk mappings. To present a new virtual disk to an host, click Add Mapping to start the Add Mapping wizard. Figure 40. Virtual Disk Mapping View 1 Select the host or host group to map to the new virtual disk. 2 Select the virtual disk number for the virtual disk to be mapped. 3 Click OK. NOTE: When your MD storage array uses multiple groups of HBAs per host, the new virtual disks should be balanced across all hosts/host groups. Do not add all the virtual disks to a single host/host group −− no I/O balancing is possible if this occurs. Dell MD Storage Array vCenter Plug-in | 51

Changing Remote Replication Parameters
To modify the parameters of a replicated pair, such as the synchronization priority, resynchronization method
and write mode, perform these steps:
1
Click
Change Replication
Parameters
.
2
Modify the dialog box to match your requirements for the replicated pair.
Removing Replicated Pairs
Removing a replicated pair breaks the replication association between the virtual disk at the primary site and
the virtual disk at the remote site. After the operation completes, the replication status between the virtual disks
is lost. For replication to be re-established, a full resynchronization must occur.
Mapping a Virtual Disk
After creating new virtual disks, use the
Mappings
tab to present the virtual disks to the ESX/ESXi host for use.
From this view, you can manage hosts, host groups and virtual disk mappings. To present a new virtual disk to
an host, click
Add Mapping
to start the Add Mapping wizard.

Select the host or host group to map to the new virtual disk.

Select the virtual disk number for the virtual disk to be mapped.

.
NOTE:
When your MD storage array uses multiple groups of HBAs per host, the new virtual disks should
be balanced across all hosts/host groups. Do not add all the virtual disks to a single host/host group
−−
no I/O balancing is possible if this occurs.
