Replacing a REM on a SPARC System

When replacing a host REM on a SPARC system, you will need to take the following actions depending on whether or not your storage module contains the host boot disk.


Note - These steps assume you have a saved configuration file from the REM that was replaced in order to retrieve virtual drive configurations. It is also assumed you have installed the new REM. Instructions for saving a configuration file are described in the LSI MegaRAID SAS Software User's Guide.


If the Storage Module Contains the Host Boot Disk

The following outlines the steps necessary when replacing a host REM that uses a disk on the storage module for OS boot.


Note - In depth instructions for performing the steps listed here are described in the appropriate Sun Storage 6Gb SAS REM HBA Installation Guide.


  1. Enter the OBP (OpenBoot PROM) environment on the host.

  2. Use the show-devs command to list available HBAs.

    • The Fusion-MPT SAS controllers (such as the Sun Storage 6Gb SAS REM HBA) will end with LSI,sas@number.

    • The MegaRAID SAS controllers (such as the Sun Storage 6Gb SAS REM RAID HBA) will end with LSI,mrsas@number.

  3. Use the show-disks command to select the storage module disk with the bootable OS installed on it.

  4. Boot from the bootable disk by using the boot device-name command.

    Where device-name is the existing alias name for the boot drive (for example: /pci@1e,600000/pci@0/pci@3/LSI,sas@0/disk). You can also assign an alias to the device using the nvalias command.

  5. Once the OS has booted, run the MegaRAID Storage Manager software.

  6. Select the controller icon in the left panel of the MegaRAID Storage Manager window for the new REM.

  7. On the menu bar, select Operations->Configuration->Add Configuration from file.

  8. As prompted, open the saved configuration file and apply the configurations.

If the Storage Module Does Not Contain the Host Boot Disk

The following outlines the steps necessary when replacing a host REM that controls disks on the storage module.


Note - In depth instructions for performing the steps listed here are described in the LSI MegaRAID SAS Software User's Guide.


  1. From the host, run the MegaRAID Storage Manager software.

  2. Select the controller icon in the left panel of the MegaRAID Storage Manager window for the new REM.

  3. On the menu bar, select Operations->Configuration->Add Configuration from file.

  4. As prompted, open the saved configuration file and apply the configurations.
