Users Guide

• CIFS supports both IPv4 and IPv6 addresses and NFS supports only IPv4 address.
• 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.
Configuring remote file share using web interface
To enable remote file sharing:
1. In iDRAC Web interface, go to Configuration > Virtual Media > Attached Media.
The Attached Media page is displayed.
2. Under Attached Media, select Attach or Auto Attach.
3. Under Remote File Share, specify the image file path, domain name, user name, and password. For information about the fields, see
the iDRAC Online Help.
Example for image file path:
• CIFS — //<IP to connect for CIFS file system>/<file path>/<image name>
• NFS —< IP to connect for NFS file system>/<file path>/<image name>
NOTE:
To avoid I/O errors when using CIFS shares hosted on Windows 7 systems, modify the following registry
keys:
• Set HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache to
1
• Set HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size to 3
NOTE: Both '/' or '\' characters can be used for the file path.
CIFS supports both IPv4 and IPv6 addresses but NFS supports only IPv4 address.
If you are using NFS share, make sure that you provide the exact <file path> and <image name> as it is case-sensitive.
NOTE:
For information on recommended characters for user names and passwords, see Recommended characters in
user names and passwords.
NOTE: The characters allowed in user names and passwords for network shares are determined by the network-
share type. iDRAC supports valid characters for network share credentials as defined by the share type, except <, >,
and , (comma).
4. Click Apply and then click Connect.
After the connection is established, the Connection Status displays Connected.
NOTE:
Even if you have configured remote file sharing, the Web interface does not display user credential
information due to security reasons.
For Linux distributions, this feature may require a manual mount command when operating at runlevel init 3. The syntax for the
command is:
mount /dev/OS_specific_device / user_defined_mount_point
where, user_defined_mount_point is any directory you choose to use for the mount similar to any mount command.
For RHEL, the CD device (.iso virtual device) is /dev/scd0 and floppy device (.img virtual device) is /dev/sdc.
