RESCHEDULE_TYPE은 일정이 변경된 업데이트의 유형입니다. 사용 가능한 값은 다음과 같습니다.
IMMEDIATE: 유지보수 업데이트를 즉시 시작합니다.
NEXT_AVAILABLE_WINDOW: 다음 유지보수 기간까지 유지보수를 연기합니다. 다음 기간은 원래 유지보수가 예약된 기간으로부터 1주일입니다.
SPECIFIC_TIME: 업데이트할 특정 시간을 지정할 수 있습니다.
재예약되는 시간이 원래 유지보수 기간으로부터 7일 이내여야 합니다.
RESHEDULE_TIME--reschedule-type을 SPECIFIC TIME으로 설정한 경우에만 이 값을 지정할 수 있습니다. 이 값은 ISO 1801 형식을 사용합니다. 예를 들면 2020-01-16T16:56:00.000Z입니다. 시간은 UTC 시간으로 설정됩니다.

For an overview\nof maintenance updates and maintenance windows, see [Maintenance policy](/memorystore/docs/redis/maintenance-policy).\n\nSet a preferred window for maintenance on an instance\n-----------------------------------------------------\n\n### Console\n\n1. Go to the **Memorystore for Redis** page in the Google Cloud console.\n\n [Memorystore for Redis](https://console.cloud.google.com/memorystore/redis/instances?)\n\n2. Click the instance ID of the instance you want to set a maintenance window\n for.\n\n3. Click **Edit**.\n\n4. Under the **Maintenance** section, select the desired day and time for the\n maintenance window. The time is set in your local time zone.\n\n5. Click **Save**.\n\n### gcloud\n\nRun the following command to set a maintenance window for a Redis instance: \n\n```\ngcloud redis instances update INSTANCE_ID --region=REGION --maintenance-window-day=DAY --maintenance-window-hour=HOUR\n```\n\nWhere:\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e is the ID of the instance\n- \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e is the region where your instance is located\n- \u003cvar translate=\"no\"\u003eDAY\u003c/var\u003e is the day you want maintenance to occur. Acceptable values are: `MONDAY`,`TUESDAY`,`WEDNESDAY`,`THURSDAY`,`FRIDAY`,`SATURDAY`,`SUNDAY`\n- \u003cvar translate=\"no\"\u003eHOUR\u003c/var\u003e is the hour of the day in UTC time for when the maintenance window starts. Acceptable values are `0`-`23`\n\nFor reference information, see [`gcloud redis instances update`](/sdk/gcloud/reference/redis/instances/update)\n\nOpt in to maintenance notifications\n-----------------------------------\n\n| **Note:** Even if you turn on maintenance notifications, you do not receive notifications unless you [set a maintenance window](/memorystore/docs/redis/finding-and-setting-maintenance-windows#set_a_preferred_window_for_maintenance_on_an_instance) for that instance.\n\nTo turn on maintenance notifications:\n\n1. Go to the **Communication** page in the Google Cloud console:\n\n [Communication](https://console.cloud.google.com/user-preferences/communication)\n2. Click the **Product Notifications** tab.\n\n3. Select your project from the dropdown menu.\n\n4. In the row for Memorystore, toggle the email button to **ON**.\n\nA maintenance notification email uses the title, `\"Upcoming maintenance for your\nCloud Memorystore instance [your-instance-name]\"`. Each email address that\nneeds to receive notifications must opt in separately.\n\nMaintenance notifications are set at the project level rather than on instances.\nEmail notifications are sent to the email address associated with your Google\naccount. It is not possible to configure a custom email alias (for instance, a\nteam email alias).\n\nFind scheduled maintenance\n--------------------------\n\nIf maintenance has been scheduled for your instance, you can view it using the\nfollowing instructions: \n\n### Console\n\n1. Go to the **Memorystore for Redis** page in the Google Cloud console.\n\n [Memorystore for Redis](https://console.cloud.google.com/memorystore/redis/instances?)\n\n2. Click the instance ID of the instance that you want to view scheduled\n maintenance for.\n\n3. Under the **Maintenance** section, you can view the date and time of any\n scheduled maintenance updates.\n\n### gcloud\n\n```\ngcloud redis instances describe INSTANCE-ID --region=REGION\n```\n\nwhere:\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e is the ID of the instance\n- \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e is the region where your instance is located\n\nThe output for scheduled maintenance is as follows: \n\n```\nmaintenancePolicy:\ncreateTime: 'TIME_STAMP'\nupdateTime: 'TIME_STAMP'\nmaintenanceWindow:\n- day: DAY\n duration: 60 minutes\n hour: HOUR\nmaintenanceSchedule:\n endTime: 'TIME_STAMP'\n startTime: 'TIME_STAMP'\n```\n\nWhere:\n\n- `maintenancePolicy` shows information on the creation time of your preferred maintenance policy and the last time the policy was updated.\n- `createTime` is when the maintenance policy is first created.\n- `updateTime` is when the maintenance policy was last updated.\n- `DAY` indicates the day of the week maintenance occurs.\n- `HOUR` indicates the hour in UTC time that maintenance begins.\n- `startTime` indicates the specific start time for a maintenance update that is scheduled for your instance.\n- `endTime` indicates the specific ending time for a maintenance update that is scheduled for your instance.\n- `TIME_STAMP` uses the RFC 3339 format.\n\nReschedule planned maintenance\n------------------------------\n\n| **Caution:** if you programmatically reschedule maintenance in bulk requests (not natively supported by Memorystore for Redis), limit batch reschedule sizes to 100 instances per batch. For more information, see [Rescheduling maintenance](/memorystore/docs/redis/maintenance-policy#rescheduling_maintenance).\n\nTo reschedule maintenance, see the instructions below: \n\n### Console\n\n| **Note:** You can only defer a maintenance update for up to one week from when a maintenance update is originally scheduled for your instance.\n\n1. Go to the **Memorystore for Redis** page in the Google Cloud console.\n\n [Memorystore for Redis](https://console.cloud.google.com/memorystore/redis/instances?)\n\n2. Click the instance ID of the instance you want to reschedule maintenance\n for.\n\n3. Under the **Maintenance** section, click **RESCHEDULE**.\n\n - You can only reschedule maintenance if you [have a scheduled update](/memorystore/docs/redis/finding-and-setting-maintenance-windows#find_scheduled_maintenance), for your instance.\n4. Choose between **Update now** , **Defer to next scheduled window** , and\n **Custom day and time** . For more information, see the [overview of rescheduling maintenance](/memorystore/docs/redis/maintenance-policy#rescheduling_maintenance).\n\n - If you want to update your instance immediately, select **Update now**\n and click **Update**.\n\n - If you want to delay the scheduled maintenance by one week, select\n **Defer to the next scheduled window** and click **Reschedule**.\n\n - If you want to designate a specific time, select **Custom day and time** ,\n choose the new time, and click **Reschedule**.\n\n### gcloud\n\n| **Note:** You can only defer a maintenance update for up to one week from when a maintenance update is originally scheduled for your instance.\n\n\u003cbr /\u003e\n\n```\ngcloud redis instances reschedule-maintenance INSTANCE_ID --region=REGION --reschedule-type=RESCHEDULE_TYPE [--schedule-time=RESHEDULE_TIME]\n```\n\nwhere:\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e is the ID of the instance\n- \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e is the region where your instance is located\n- \u003cvar translate=\"no\"\u003eRESCHEDULE_TYPE\u003c/var\u003e is the type of rescheduled update.
