Openfiler – Configuring an iSCSI resource

Introduction

Openfiler can be used to provide iSCSI disks across the network to other hosts and in this article the steps to provide a iSCSI resource on the server are explained.

Creating iSCSI volumes

The final step in configuring the storage on the server is to create the volumes required.  These will be the volumes used to present iSCSI disks to the network.

To create an iSCSI volume perform the following steps :-

  1. Click on the Volumes option and then click on the Add Volume option in the Volumes section
  2. Choose the Volume Group name desired from the dropdown – E.G. Lost-it-vg
  3. Scroll down to the bottom of the screen if necessary and then enter the volume name required – E.G. iSCSI-Disk-1
  4. Set the description to a meaningful description – E.G. iSCSI based disk 1
  5. Set the required space to the desired size of the volume – E.G. 5120 MB for 5GB
  6. Set the Filesystem / Volume Type to iSCSI and then click on the Create button to create the volume.

Enabling the required Services

Once the volumes and volume groups have been configured the next step is to enable the Services required to provide Windows Share and iSCSI resource access on the server.  To configure the services perform the following steps :-

  1. Click on the Services option
  2. Click on Enable next to the iSCSI Target Server service to enable access to iSCSI resources

Configuring an iSCSI target

To configure an iSCSI target perform the following steps :-

  1. Click on the Volumes option and then click on the iSCSI Targets option in the Volumes section
  2. When prompted either configure the IQN for the iSCSI target or click on the Add button to accept the default generated address.
  3. Click on the LUN Mapping tab and click on the Map button to add the LUN mapping.
  4. Next click on the Network ACL tab and set the networks required for access to Allow.
  5. Click on the Update button to configure the Network ACL for the iSCSI target.
