Change replication session settings

Change the settings for a replication session.

Format

/prot/rep/session {–id <value> | -name <value>} set [-async] [-newName <value>] [-srcSPAInterface <value>] [-dstSPAInterface <value>] [-srcSPBInterface <value>] [-dstSPBInterface <value>] [-syncType {manual | auto [-rpo <value>]}] [-replicateHourlySnaps {yes [{-keepSameAsSource | -keepFor <value> | -allowAutoDelete}] | no}] [-replicateDailySnaps {yes [{-keepSameAsSource | -keepFor <value> | -allowAutoDelete}] | no}] [-allowAsyncSnapReplication {yes [-cascadeReplicatedSnap {yes | no}] | no}]

Object qualifiers

Qualifier	Description
-id	Type the ID of the replication session to change.
-name	Type the name of the replication session to change.

Action qualifiers

Qualifier	Description
-async	Run an action in asynchronous mode.
-newName	Type the new name of the replication session.
-srcSPAInterface	Type the ID of the interface on the SPA of the source system for the replication. NOTE:This qualifier is used for asynchronous replications on remote systems only. If the qualifier is not specified, the system identifies the interface automatically.
-srcSPBInterface	Type the ID of the interface on the SPB of the source system for the replication. NOTE:This qualifier is used for asynchronous replications on remote systems only. If the qualifier is not specified, the system identifies the interface automatically.
-dstSPAInterface	Type the ID of the interface on the SPA of the destination system for the replication. NOTE:This qualifier is used for asynchronous replications on remote systems only. If the qualifier is not specified, the system identifies the interface automatically.
-dstSPBInterface	Type the ID of the interface on the SPB of the destination system for the replication. NOTE:This qualifier is used for asynchronous replications on remote systems only. If the qualifier is not specified, the system identifies the interface automatically.
-syncType	This parameter indicates whether to perform the first replication sync (a full sync) automatically. The following example shows the `manual` option used for the first replication sync: -syncType {manual \| auto [-rpo <`value`>} Valid values are: manual—Data is replicated when manually initiated. auto [-rpo <value>]—Data is replicated automatically in order to maintain the wanted Recovery Point Objective (RPO). NOTE:This qualifier is used for asynchronous replications only. As the RPO increases, the potential for data loss also increases, and the amount of required protection space. Lowering the RPO reduces the amount of potential data loss, but also increases network traffic and may negatively impact performance. The default RPO is one hour.
-rpo	For automatic synchronization, type the time interval for when the synchronization will run. Use the following format: <HH>[:MM] Where: HH—Type the number of hours. Range is 00-24 hours (1 day). MM—Type the number of minutes, in 5 minute increments. Range is 05 to 55. NOTE:For synchronous replication, specify the value 0. The value cannot be reset from zero to nonzero or from nonzero to zero.
-replicateHourlySnaps	Specify whether to mark hourly scheduled snapshots for replication. Valid values are: yes no NOTE:This qualifier is used for asynchronous replications only.
-replicateDailySnaps	Specify whether to mark daily scheduled snapshots for replication. Valid values are: yes no NOTE:This qualifier is used for asynchronous replications only.
-keepSameAsSource	Specify whether to use the same retention policy (expiration time and auto-delete) of the source for the destination. This option propagates changes that are made to the source retention policy to the destination retention policy (from that point forward for newly created scheduled snapshots, old snapshots are left as is). No values are allowed. NOTE:This qualifier is used for asynchronous replications only.
-keepFor	Specify the retention time after which the snapshot is deleted on the destination. The interval can be defined in days or hours. Use the following format: `<value><qualifier>` Where: `value`—An integer value. If the `qualifier` is h (hours), the valid range is from 1 to 42840. If the `qualifier` is d (days), the valid range is from 1 to 1785. `qualifier`—A value qualifier. The valid values are: h (hours) d (days) NOTE:This qualifier is used for asynchronous replications only.
-allowAutoDelete	NOTE:Only valid when `-replicateHourlySnaps yes` or `-replicateDailySnaps yes`. Specify whether auto delete is allowed on the replicated copy of this snapshot or snapshot set. Valid values are: yes no NOTE:This qualifier is used for asynchronous replications only.
-allowAsyncSnapReplication	Indicates whether to allow snapshot replication in asynchronous session. Valid values are: yes no
-cascadeReplicatedSnap	Indicates whether to replicate snapshots in the cascade replication session. This qualifier can only be modified when the session is active. Valid values are: yes no (default)
