# update

## Usage

```
ionosctl compute server update [flags]
```

## Aliases

For `server` command:

```
[s svr]
```

For `update` command:

```
[u up]
```

## Description

Use this command to update a specified Server from a Virtual Data Center.

You can set the RAM size in the following ways:

* providing only the value, e.g.`--ram 256` equals 256MB.
* providing both the value and the unit, e.g.`--ram 1GB`.

The amount of memory for the Server must be specified in multiples of 256. The default unit is MB. Minimum: 256MB. Maximum: it depends on your contract limit.

Note: For CUBE Servers, only Name attribute can be updated.

Use `--wait` (`-w`) to wait for the resource to reach AVAILABLE state.

Required values to run command:

* Data Center Id
* Server Id

## Options

```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionos.com/cli-ionosctl/subcommands/compute-engine/server/update.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
