rladmin is a command-line utility for performing administrative tasks such as failover, migration, and endpoint binding on a Redis Enterprise Software cluster. rladmin can also edit cluster and database configurations. Some of these tasks can also be performed through the admin console and some are unique to the rladmin CLI tool.

rladmin Commands

Command Description
rladmin Enter the rladmin shell
bind Bind an endpoint
cluster Cluster management commands
exit Exit rladmin shell
failover Fail over a master shard to replica shard (previously slave shard)

recover Recover databases
restart Restart database shards
status Show status information

rladmin bind manages the proxy policy for the cluster or a specific database. It also can include or exclude endpoints from the proxy policy.

rladmin bind 
        [ db <db:id | name> ] 
        endpoint <id> 
        policy <single | all-master-shards | all-nodes>
Proxy policy Description
all-master-shards Multiple proxies, one on each master node (best for high traffic and multiple master shards)
all-nodes Multiple proxies, one on each node of the cluster (increases traffic in the cluster, only used in special cases)
single All traffic flows through a single proxy bound to the database endpoint (preferable in most cases)
rladmin bind 
        [ db <db:id | name> ] 
        endpoint <id> [ include | exclude ] 
        proxy <id1 .. idN>


rladmin cluster manages cluster configuration and administration. Most rladmin cluster commands are only for clusters that are already configured, while a few others are only for new clusters that have not been configured.

Command (for configured clusters) Description

redis_provision_node_threshold Memory (in MBs) needed to provision a new database
redis_provision_node_threshold_percent Memory (in percentage) needed to provision a new database
redis_upgrade_policy When you upgrade or create a new Redis database, this policy determines which version of Redis database compatibility is used.

Supported values are:
  • latest, which applies the most recent Redis compatibility update (effective default prior to v6.2.4)

  • major, which applies the most recent major-release compatibility update (default as of v6.2.4).
repl_diskless Enables/disables diskless replication (can be overwritten per database)
slave_ha Enables/disables slave high availability
slave_ha_bdb_cooldown_period Time (in seconds) after shard relocation during which databases can’t be relocated to another node
slave_ha_cooldown_period Time (in seconds) after shard relocation during which the slave high availibity mechanism can’t relocate to another node
slave_ha_grace_period Time (in seconds) between when a node fails and when slave high availability starts relocating shards to another node
watchdog_profile Enables pre-configured watchdog profiles ( cloud or local-network)

Redis cluster watchdog supports two pre-configured profiles:

  • cloud profile is suitable for common cloud environments. It has a higher tolerance for network jitter.
  • local-networkprofile is suitable for dedicated LANs and has a better failure detection and failover times.


rladmin upgrade schedules a restart of the master and slave processes to upgrade the Redis software for a specific database instance.

rladmin upgrade db <db:id | name> 
        [ preserve_roles ] 
        [ keep_current_version ] 
        [ discard_data ] 
        [ force_discard ]
        [ parallel_shards_upgrade ]
        [ keep_crdt_protocol_version ]
        [ force ]
        [ and module module name <module name> version <version> module_args <args_str> ]
Optional Parameters Description
and module Clause that allows upgrade of BDB and specified Redis module in a single step with only one restart (can be specified multiple times)
discard_data Indicates that data will not be saved after the upgrade
force Forces upgrade and skips warnings and confirmations
force_discard Forces discard_data if there is replication or persistence enabled
keep_crdt_protocol_version Keeps the current crdt protocol version
keep_current_version Upgrades to a new patch release, not to the latest major.minor version
preserve_roles Performs an additional failover to guarantee roles of masters are preserved

As of v6.2.4, the default behavior for upgrade db has changed. It is now controlled by a new parameter that sets the default upgrade policy used to create new databases and to upgrade ones already in the cluster. To learn more, see tune cluster default_redis_version.
