Configure exclusive block level access with iSCSI on MS Windows

iSCSI is used to give exclusive block level controlled disk to a server.  The server’s operating system sees the remote disk as if it were local. To configure iSCSI on Linux CentOS, go to this page.

Add a disk do your account and allow your server to access it.

    Using nscmd Command Line Tool:

1. nscmd addDisk 250GB (note the diskId, diskIpAddress, and initiatorName)
2. nscmd enableDiskService [diskId] iscsi
3. nscmd grantDiskAccess [diskId] [diskIpAddress]

1. https://noc.newservers.com/api/addDisk?username=you&password=yourpass&size=250(note the id, disk-ip-address, and initiator-name)
2. https://noc.newservers.com/api/enableDiskIscsi?username=you&password=yourpass&diskId=[id]&service=iscsi
3. https://noc.newservers.com/api/grantDiskAccess?username=you&password=yourpass&diskId=[id]&address=[serverIpAddress](serverIpAddress is the ip of the server you wish to allow connection to the disk)

1. Login
2. Go to 'Storage' and click on 'Add Dedicated Disk' or 'Add SAN Volume'. Choose the size and click on 'Add now'.
3. Under 'Active Disk List' click on the newly added disk. Note the Disk Ip Address, and Initiator Name. Set the IP address that will be allowed to access the disk using the drop down menu or enter it manually. Check 'Enable iSCSI'. Click 'Save'.

Setup disk on server Instructions (windows):

1. Run ‘Microsoft iSCSI Initiator’ from your server’s desktop. You can download it from Here if its not already on your desktop
2. Go to the Discovery tab. Under category ‘Target Portals’ click 'Add'.

Under ‘IP address or DNS name:’ enter the diskIpAddress and leave the default port 3260 as it is. Click Ok.

3. Now go to the Targets tab.

Click on 'Refesh', the iqn (iSCSI qualified name) of the disk you previously added should appear in the Targets list. The format is iqn:diskID.serverID.newservers.com. The status of the iqn will be Inactive. Click ‘Log On…’, check the option ‘Automatically restore this connection when the system boots’. Now click on Advanced button and here use the following settings:

Local adapter: select Microsoft iSCSI Initiator
Source IP: select your server IP here (the one you allowed to connect to the disk)
Target Portal: select the diskIpAddress and the port 3260

Click Ok on both windows to return to ‘iSCSI Initiator Properties’ main window. Now the Status of the iqn will be ‘Connected’.

4. Under Persistent Targets tab you will see now the iqn. Next go to the ‘Bound Volumes/Devices'

Click on Bind All button. The iSCSI volume will appear now. Click Ok to close the iSCSI Properties window.

5. Go to Computer Management console and click on Disk Management

Here you will see the iSCSI volume as ‘Disk 1’. You will have to delete the current unknown partition and then create a new primary NTFS volume on the unallocated volume and format it. After this the volume will appear in My Computer with the drive letter you used when formating.
