Configure iSCSI Target
2011/04/18 |
| Configure Storage Server with iSCSI.
A storage on a network is called iSCSI Target, a Client which connects to iSCSI Target is called iSCSI Initiator.
This example is based on the environment below. dlp.srv.world [10.0.0.30] - iSCSI Target www.srv.world [10.0.0.31] - iSCSI Initiator This example configures to create LVM partition on iSCSI Target, so it need to have enough areas to use. If your iSCSI Target does not have enough areas, add new hard drive. |
