Users Guide

● CIFS and NFS supports both IPv4 and IPv6 addresses.
● When the iDRAC is configured with both IPv4 and IPv6, the DNS server can contain records associating the iDRAC hostname to
both addresses. If IPv4 option is disabled in iDRAC, then iDRAC may not be able to access the external IPv6 share. This is because
the DNS server may still contain IPv4 records, and DNS name resolution can return the IPv4 address. In such cases, it is
recommended to delete the IPv4 DNS records from the DNS server, when disabling IPv4 option in iDRAC.
● If you are using CIFS and are part of an Active Directory domain, enter the domain name with the IP address in the image file
path.
● If you want to access a file from an NFS share, configure the following share permissions. These permissions are required because
iDRAC interfaces run in non-root mode.
○ Linux: Ensure that the share permissions are set to at least Read for the Others account.
○ Windows: Go to the Security tab of the share properties and add Everyone to Groups or user names field with Read &
execute privilege.
● If ESXi is running on the managed system and if you mount a floppy image (.img) using RFS, the connected floppy image is not
available to the ESXi operating system.
● iDRAC vFlash feature and RFS are not related.
● Only English ASCII characters are supported in network share file paths.
● The OS drive eject feature is not supported when virtual media is connected using RFS.
● RFS through HTTP or HTTPs feature is not available on CMC web interface.
● RFS may get disconnected when iDRAC IP is not reachable for more than 1 minute.
使用 Web 界面配置远程文件共享
启用远程文件共享：
1. 在 iDRAC Web 界面中，转至配置 > 虚拟介质 > 已附加介质。
将显示已附加介质页面。
2. 在已附加介质下，选择附加或自动附加。
3. 在远程文件共享下，指定映像文件路径、域名、用户名和密码。有关各字段的信息，请参阅 iDRAC Online Help（iDRAC 联机帮
助）。
映像文件路径示例：
● CIFS — //<IP to connect for CIFS file system>/<file path>/<image name>
● NFS — < IP to connect for NFS file system>:/<file path>/<image name>
● HTTP — http://<URL>/<file path>/<image name>
● HTTPs — https://<URL>/<file path>/<image name>
注: 为避免 I/O 错误，使用在 Windows 7 系统上托管的 CIFS 共享时，请修改以下注册表项：
● 将 HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache 设置为 1
● 将 HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size 设置为 3
注: “/”或“\”字符均可用于文件路径。
CIFS 支持 IPv4 和 IPv6 地址，但 NFS 仅支持 IPv4 地址。
如果使用 NFS 共享，因为会区分大小写，请确保提供准确的 <文件路径> 和 <映像名称> 。
注: 有关用户名和密码的建议字符信息，请参阅 建议使用的用户名和密码字符 页面上的 134。
注: 网络共享的用户名和密码中允许的字符由网络共享类型决定。iDRAC 支持通过共享类型定义的网络共享凭据的有效字
符，但 <、> 和 ,（逗号分隔）除外。
4. 单击应用，然后单击连接。
在建立连接后，连接状态显示为已连接。
注: 即使已配置远程文件共享，出于安全原因，Web 界面也不会显示用户凭据信息。
注: 如果映像路径包含用户凭据，请使用 HTTPS 以避免凭据显示在 GUI 和 RACADM 中。如果在 URL 中输入凭据，请避免使
用“@”符号，因为这是一个分隔符。
