Primary Group Replication Attributes
Table 49. Primary Volume Replication Attributes describes attributes that you set when you congure a volume for replication in the
primary group. You can modify the replication conguration 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 congure a replication partner, you specify values for the attributes described in Table 50. Replication Partner Attributes.
You can also modify the partner conguration and change the attribute settings as needed.
Table 50. Replication Partner Attributes

name is case sensitive and can accept up to 54 ASCII characters.

are accepted for this eld if you type the value as a Unicode character string, which takes up a
variable number of bytes, depending on the specic character.

Fewer characters are accepted for this eld if you type the value as a Unicode character string,

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.
