Configure a Host Storage Device Redirection Session

Language:

Use the Host Storage Device feature in Oracle ILOM to mount a remote image file on the server service processor (SP), and then redirect the file to the host server. The image appears to the host server as an attached storage device.

The Host Storage Device feature is useful in the following situations:

You want to boot multiple Oracle servers from a single (ISO) image file that is stored on a remote server.
You want to update multiple Oracle servers using a single (VFAT) image file that is stored on a remote server.

You can only redirect one image file at a time from any of the Oracle ILOM interfaces. Additionally, you cannot use the Host Storage Device feature while another type of redirection is in progress. If you attempt to redirect an image file when another storage redirection session is in progress on the SP, the storage redirection attempt will fail and an error message will appear.

Before You Begin

Ensure that the following requirements are met:

You have Admin (a) role privileges in Oracle ILOM.
If required, you have user credentials on the NFS or SAMBA central repository server where the image file is located.

To configure a host storage device redirection in the Oracle ILOM web interface:
1. Log in to the Oracle ILOM web interface.
  For instructions, see Accessing Oracle ILOM.
2. In the navigation pane, click Remote Control → Host Storage Device.
3. Select Remote from the Mode drop-down menu.
4. Enter the location of the image on the remote server using either the NFS or Samba protocol.
  - To enter a URI using NFS, use the format: nfs://server:/path/file
    For example:
    
    nfs://192.0.2.22:/export/netadmin1/biosimage.img
  - To enter a URI using Samba, use the format: smb://server:/path/file or smb://server/path/file.
    For example:
```
smb://192.0.2.22/netadmin1/biosimage.img
```
5. Click Save.
  The status of the redirection appears in the Status field.
6. When you are done, to disable redirection, select Disabled from the Mode drop-down menu and click Save.
To configure a host storage device redirection in the Oracle ILOM command-line interface (CLI):
1. Log in to the Oracle ILOM CLI.
  For instructions, see Accessing Oracle ILOM.
2. Set the location of the image file by typing:
  set /SP/services/kvms/host_storage_device/remote/server_URI=NFS_or_Samba_URI_file_location [username=username] [password=password]
3. Enable storage redirection by typing:
  set /SP/services/kvms/host_storage_device/ mode=remote
4. To view the status of redirection, type the command:
  show /SP/services/kvms/host_storage_device/ status
  
  Note - Redirection is active is the status if set to either Operational or Connecting.
5. When you are done, disable redirection by typing:
  set /SP/services/kvms/host_storage_device/ mode=disabled
