How to configure a two node iSCSI configuration

We do not support clustering with the 15200 as we found it not to be reliable in our testing.    I recommend you persuade your customer to migrate to a VTrak M500i system that is capable of clustering (up to 8-nodes for Windows, RedHat, and SuSE).

Regardless, you can study the steps below on how to configure a two node iSCSI configuration and assist your customer on the functionality aspects.    But he will need to use the 15200 at his own risk.

 

iSCSI Cluster Testing 2 Node:

Note: This is a bare minimum setup.  The Client Test System would normally run the HCT Cluster Storage Block Device, not the PDC.

 

PART I Testing – Cluster Hardware

 

To CONFIGURE the test for Cluster Storage Block Hardware testing:

1.       Begin with the configuration for hardware testing.

      Computer 1 = Cluster Node 1 [Dell PowerEdge 800 Server]

      Computer 2 = Cluster Node 2 [Dell PowerEdge 800 Server]

      Computer 3 = Primary Domain Controller [Dell PowerEdge 800 Server]

2.       Connect nodes 1 and 2 to a 10/100 based switch.  This will be the  "Private Network", e.g. 30.0.0.x

3.       Connect nodes 1 and 2, and the PDC to the Gb LAN switch.  This will be the "Public Network", e.g. 40.0.0.x

4.       Connect nodes 1 and 2 iSCSI, to the Gb LAN switch.  This will be the "iSCSI Network", e.g. 20.0.0.x.

5.       Attach both Promise VTrak iSCSI ports to the Gb LAN switch.

6.       Connect the "Public Network" & "iSCSI Network" to a common public network switch (Nortel 1Gb Ethernet Switch). 

7.       The "iSCSI Network" and "Public Network" can be configured as separate private networks within the same LAN switch.

8.       From a factory defaulted Promise VTrak configure the following Disk Arrays:

1.       Disk Array 1 = RAID 5, 64KB SBS, WriteBack Cache using PD: 1~4 with 1x10GB LD

2.       Disk Array 2 = RAID 1, 64KB SBS, WriteBack Cache using PD: 5~6 with 1x10GB LD

3.       Disk Array 3 = RAID 0, 64KB SBS, WriteBack Cache using PD: 7~10 with 1x10GB LD

9.       Enable auto logon in the iSCSI Initiator software.

10.   Login all Nodes to the VTrak iSCSI RAID Systems.

11.   From node 1, use the New Partition Wizard within Disk Management to create three 6 GB partitions. Create the first partition on disk 1, and name the partition E. Create the second partition on disk 2, and name the partition F. Create the third partition on disk 3 and name the partition G. Make all three NTFS partitions, and enable file and folder compression.

12.   Restart node 2.

13.   On node 2, open Disk Management and verify that disks 1, 2, and 3 are formatted properly.  Do not rewrite signatures, repartition, or reformat.

14.   On node 2, name the partition on drive 1 E, name the partition on drive 2 F, and name the partition on drive 3 G.

 

To RUN the test for Cluster Storage Block Hardware testing:

15.   Install the HCT 12.1.01 on nodes 1 and 2. PDC is not needed to run the HCT Cluster Storage Block Hardware.

16.   During installation, you are prompted to select a test kit.  De-select any pre-selected test categories.   In the Custom Setup window, expand Test Categories, expand Storage Controllers and Devices, expand Storage Block Devices, and then select This feature, and all subfeatures, will be installed on the local hard drive.

When the HCT kit is installed, restart the computer.

17.   Click Start; point to All Programs; click HCT; and then click HCT 12.1.

18.   When Test Manager is finished scanning the system for new hardware, the Test Selection Wizard pane appears. Confirm that Storage Block Devices is not selected in the Categories column.

19.   Click Next.

20.   On the left pane, in the Device Name column, select the MS iSCSI Initiator or iSCSI HBA that is connected to the RAID system.

When the installation is complete, click Finish.

21.   On node 1, start the HCT Test Manager and click Client Server Phase 1: Client, and then click Add Selection. Manually enter the number of nodes in parameter #2, click OK and Start Tests.

22.   On node 2, start the HCT Test Manager and click Client Server Phase 1: Server, and then click Add SelectionManually enter the name of node 1 in parameter #2, click OK and Start Tests.   

23.   Verify that all nodes passed.

 

 

PART II Testing – Cluster Device Services

 

To CONFIGURE the test for Cluster Storage Block Device testing:

1.       Begin with the configuration for hardware testing.

      Computer 1 = Cluster Node 1 [Dell PowerEdge 800 Server]

      Computer 2 = Cluster Node 2 [Dell PowerEdge 800 Server]

      Computer 3 = Primary Domain Controller [Dell PowerEdge 800 Server]

 

To CONFIGURE the tests for Cluster Storage Block Device Services testing:

2.       From a factory defaulted Promise VTrak configure the following Disk Arrays:

A.      Disk Array 1 = RAID 5, 64KB SBS, WriteBack Cache using PD: 1~4 with 3x10GB LD.  (Need 1 LD for each Node, and 1 LD for Quorum)

3.       Enable auto logon in the iSCSI Initiator software.

4.       Login all Nodes to the VTrak iSCSI RAID Systems.

5.       On node 1, use Windows Disk Management to reformat disk 1-3 with the NTFS file system. Do not select the Quick Format option. You should select the Enable File and Folder Compression option.

6.       Verify that nodes 1and 2 recognize the shared disks. (Do not rewrite signatures, repartition, or reformat)
