ReinstallInstance

1. API Description

This API is used to reinstall the operating system of the specified instance.

Prerequisites

Query image: call DescribeImages to check information on image.

Note

• If you specify an imageId, the specified image is used. Otherwise, the image used by the current instance is used.

• Operations on instances in recycle bin or in stalling status are not supported.

• The system disk will be formatted and reset. Therefore, make sure that no important files are stored on the system disk.

• If no password is specified, you will get a random password via mailbox.

• The status of the instance will be INSTALLING during reinstallation. You can use DescribeInstances to query the status of the instance. If the status changes to Running, it means that the instance has been reinstalled successfully; INSTALL_FAILED means the instance has been reinstalled failed. Any operations on the instances are not allowed while creating. Please contact Zenlayer Support if you have failed.

2. Input Parameters

The following request parameter list only provides API request parameters.

Parameter Name	Required	Type	Description
instanceId	Yes	String	Instance ID. To obtain the instance ID, you can call DescribeInstances and look for instanceId in the response.
imageId	No	String	Valid image ID. To obtain valid image ID, you can call DescribeImages , pass in instanceTypeId to retrieve the list of images supported by the current model, and then find the imageId in the response. You can also not specify an image and install it later through IPMI. When using iPXE to install OS, pass the value of ipxeUrl, and leave imageId empty.
ipxeUrl	No	String	iPXE URL. Pass in the value and install your OS via IPMI. You can choose to install OS using Netboot. See Deploy a Custom Image Using iPXE for more details.
hostname	No	String	Instance hostname. Default value: hostname. This parameter can contain up to 64 . characters. Only letters, numbers, - and periods (.) are supported.
password	No	String	Instance password. The parameter must be 8-16 characters, including uppercase letters, lowercase letters, numbers and special characters like 1~!@$^*-_=+. This password is also used as the password for IPMI login. Please keep it safe. You must and can only pass the value of either password or sshKeys.
sshKeys	No	Array of String	List of SSH keys. If an SSH key is used to log in, password login will be disabled. Up to 5 keys are supported. Note: For instances of Windows and EXSi operating systems, ignore this parameter. Default value is empty. Even if this parameter is filled in, only the value of password will be passed in. If imageId is not specified, then sshKeys will be ignored. You must and can only pass the value of either password or sshKeys.
raidConfig	No	RaidConfig	Disk array configuration.
partitions	No	Array of Partition	Disk partition configuration. If the operating system is not installed, the partition cannot be set.
nic	No	Nic	NIC configuration.

3. Output Parameters

Parameter Name	Type	Description
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
