Primary Group Replication Attributes Table 49. Primary Volume Replication Attributes describes attributes that you set when you configure a volume for replication in the primary group. You can modify the replication configuration and change the attribute values. Table 49. Primary Volume Replication Attributes Attribute Description Replication partner Partner that stores the volume replicas. The partner must have space delegated to the group. Local replication reserve percentage Space for use during replication and, optionally, for storing the failback snapshot. This space is consumed from the same pool as the volume. Local replication borrow space setting Enabled by default. Can be disabled only from the CLI. Failback snapshot setting Enables you to keep the failback snapshot in the local replication reserve. The failback snapshot can expedite failback operations. Replica reserve percentage Portion of delegated space on the partner for storing replicas based on the volume usage. Replication Partner Attributes You can modify the name, group IP address, amount of delegated space and its pool, passwords, and contact information for a replication partner. NOTE: • Replication partner changes you make on the secondary group are not updated on the primary group until the next replication. • On the replication partner, if you create a container with an SMB share and use a container name that already exists, enabling read-only access on the replica container fails, but no indication of the failure is returned. An event is generated in the event log indicating that the failure was due to a duplicate share name. When you configure a replication partner, you specify values for the attributes described in Table 50. Replication Partner Attributes. You can also modify the partner configuration and change the attribute settings as needed. Table 50. Replication Partner Attributes Attribute Description Group name and group IP address Name and IP address of the group that you want to configure as a replication partner. The group name is case sensitive and can accept up to 54 ASCII characters. Description Optional description for the partner. Descriptions can be up to 63 characters. Fewer characters are accepted for this field if you type the value as a Unicode character string, which takes up a variable number of bytes, depending on the specific character. Contact information Optional contact information for the partner administrator: Name - Up to 63 characters. Email address - Up to 31 characters. Phone numbers - Up to 31 characters. Fewer characters are accepted for this field if you type the value as a Unicode character string, which takes up a variable number of bytes, depending on the specific character. Two passwords Passwords for mutual authentication. Each partner supplies a password to the other partner, which validates the password: the inbound password on one partner is the outbound password on the other, and vice versa.

Primary Group Replication Attributes
Table 49. Primary Volume Replication Attributes
describes attributes that you set when you
configure
a volume for replication in the
primary group. You can modify the replication
configuration
and change the attribute values.
Table 49. Primary Volume Replication Attributes
Attribute
Description
Replication partner
Partner that stores the volume replicas. The partner must have space delegated to the
group.
Local replication reserve percentage
Space for use during replication and, optionally, for storing the failback snapshot. This
space is consumed from the same pool as the volume.
Local replication borrow space setting
Enabled by default. Can be disabled only from the CLI.
Failback snapshot setting
Enables you to keep the failback snapshot in the local replication reserve. The failback
snapshot can expedite failback operations.
Replica reserve percentage
Portion of delegated space on the partner for storing replicas based on the volume usage.
Replication Partner Attributes
You can modify the name, group IP address, amount of delegated space and its pool, passwords, and contact information for a
replication partner.
NOTE:
Replication partner changes you make on the secondary group are not updated on the primary group until the next
replication.
On the replication partner, if you create a container with an SMB share and use a container name that already exists,
enabling read-only access on the replica container fails, but no indication of the failure is returned. An event is generated in
the event log indicating that the failure was due to a duplicate share name.
When you
configure
a replication partner, you specify values for the attributes described in
Table 50. Replication Partner Attributes
.
You can also modify the partner
configuration
and change the attribute settings as needed.
Table 50. Replication Partner Attributes

which validates the password: the inbound password on one partner is the outbound password on
the other, and vice versa.
