Sun Cluster 3.0 U1 Release Notes Supplement

Dual SCSI Port Hosts

  1. Connect the cables to the Netra D130/StorEdge S1 enclosures, as shown in Figure D-4.

    Make sure that the entire SCSI bus length to each Netra D130 enclosures is less than 6 m. The maximum SCSI bus length for the StorEdge S1 is 12 m. This measurement includes the cables to both nodes, as well as the bus length internal to each Netra D130/StorEdge S1 enclosures, node, and host adapter. Refer to the documentation that shipped with the Netra D130/StorEdge S1 enclosures for other restrictions regarding SCSI operation.

  2. Connect the cables to the Netra D130/StorEdge S1 enclosures, as shown in Figure D-4.

    Make sure that the entire SCSI bus length to each Netra D130 enclosures is less than 6 m (12 m for the StorEdge S1). This measurement includes the cables to both nodes, as well as the bus length internal to each Netra D130/StorEdge S1 enclosures, node, and host adapter. Refer to the documentation that shipped with the Netra D130/StorEdge S1 enclosures for other restrictions regarding SCSI operation.

  3. Connect the AC or DC power cord for each Netra D130/StorEdge S1 enclosures of the mirrored pair to a different power source.

  4. Power on the first node but do not allow it to boot. If necessary, halt the node to continue with OpenBootTM PROM (OBP) Monitor tasks (the first node is the node with an available SCSI address).

  5. Find the paths to the host adapters. 


    {0} ok show-disks
a) /pci@1f,4000/pci@4/SUNW,isptwo@4/sd
b) /pci@1f,4000/pci@2/SUNW,isptwo@4/sd

    Identify and record the two controllers that will be connected to the storage devices, and record these paths. Use this information to change the SCSI addresses of these controllers in the nvramrc script in Step 6. Do not include the /sd directories in the device paths.

  6. Edit the nvramrc script to set the scsi-initiator-id for the host adapters on the first node.

    For a full list of nvramrc editor and nvedit keystroke commands, see the OpenBoot 3.x Command Reference Manual.

    The following example sets the scsi-initiator-id to 6. The OpenBoot PROM Monitor prints the line numbers (0:, 1:, and so on).

    Note -

    Insert exactly one space after the first quotation mark and before scsi-initiator-id. 


    {0} ok nvedit 
0: probe-all
1: cd /pci@1f,4000/pci@4/SUNW,isptwo@4
2: 6 " scsi-initiator-id" integer-property 
3: device-end 
4: cd /pci@1f,4000/pci@2/SUNW,isptwo@4 
5: 6 " scsi-initiator-id" integer-property 
6: device-end 
7: install-console 
8: banner <Control C> 
{0} ok

  7. Store the changes.

    The changes you make through the nvedit command are done on a temporary copy of the nvramrc script. You can continue to edit this copy without risk. After you complete your edits, save the changes. If you are not sure about the changes, discard them.

    • To store the changes, type:


      {0} ok nvstore
{0} ok

    • To discard the changes, type:


      {0} ok nvquit
{0} ok

  8. Verify the contents of the nvramrc script you created in Step 6, as shown in the following example.

    If the contents of the nvramrc script are incorrect, use the nvedit command to make corrections.


    {0} ok printenv nvramrc 
nvramrc =             probe-all
                      cd /pci@1f,4000/pci@4/SUNW,isptwo@4
                      6 " scsi-initiator-id" integer-property 
                      device-end 
                      cd /pci@1f,4000/pci@2/SUNW,isptwo@4
                      6 " scsi-initiator-id" integer-property  
                      device-end  
                      install-console
                      banner
{0} ok

  9. Instruct the OpenBoot PROM Monitor to use the nvramrc script.


    {0} ok setenv use-nvramrc? true
use-nvramrc? = true
{0} ok

  10. Power on the second node but do not allow it to boot. If necessary, halt the node to continue with OpenBoot PROM Monitor tasks (the second node is the node that has SCSI address 7).

  11. Verify that the scsi-initiator-id for the host adapter on the second node is set to 7.

    Use the show-disks command to find the paths to the host adapters connected to these enclosures (as in Step 5). Select each host adapter's device tree node, and display the node's properties to confirm that the scsi-initiator-id for each host adapter is set to 7, as shown in the following example.


    {0} ok cd /pci@1f,4000/pci@4/SUNW,isptwo@4
{0} ok .properties
...
scsi-initiator-id        00000007
...
{0} ok cd /pci@1f,4000/pci@2/SUNW,isptwo@4
{0} ok .properties
...
scsi-initiator-id        00000007

  12. Continue with the Solaris operating environment, Sun Cluster software, and volume management software installation tasks.

    For software installation procedures, see the Sun Cluster 3.0 U1 Installation Guide.
