Note Cloud DB for Cache CLI offers two versions based on the supported DBMS range. - rebootCloudCacheServerInstance CLI: Support for Valkey and Redis DBMS - rebootCloudRedisServerInstance CLI: Support for Redis DBMS ## rebootCloudCacheServerInstance CLI This section describes the command syntax, options, commands, and output examples for the rebootCloudCacheServerInstance CLI. ### Syntax The `rebootCloudCacheServerInstance` syntax is as follows: ``` ./ncloud vcache rebootCloudCacheServerInstance \ --cloudCacheServerInstanceNo \ [--regionCode ] \ [--output ] ``` ### Options This section describes the options available when running `rebootCloudCacheServerInstance`. #### Required options The following options are required for `rebootCloudCacheServerInstance`. | Options | Type | Required | Description | | --- | --- | --- | --- | | `--cloudCacheServerInstanceNo` | String | Required | Cloud DB for Cache server instance number - Restarts can cause data loss, and for standalone servers without the high availability feature enabled, all data is deleted. - On Cache Cluster products with high availability (HA) enabled, restarting the master occurs after a failover, so the role changes after the restart. - See [getCloudCacheInstanceList](/docs/en/cli-vcache-getcloudcacheinstancelist). | #### Common options For information about the options common to all `vcache` subcommands, see [Cloud DB for Cache (VPC) options](/docs/en/cli-vcache#%EC%98%B5%EC%85%98). ### Examples If the request to restart a Cloud DB for Cache server instance is successful, the configuration information for the Cloud DB for Cache instance and the details for each server instance are returned. #### Command The command example is as follows: ``` ./ncloud vcache rebootCloudCacheServerInstance \ --cloudCacheServerInstanceNo 45678902 \ --regionCode KR \ --output json ``` #### Output The output example is as follows: ``` { "rebootCloudCacheServerInstanceResponse": { "totalRows": 1,
