Chapter 1: Overview
Hardware Specifications
Follow these steps to migrate drives:
1. Make sure that you clear the configuration on the system to which you migrate the drives to prevent a
configuration data mismatch between the drives and the NVRAM.
2. Turn off power to the server and all drives, enclosures, and system components. Disconnect the power cords from
the systems.
3. Open the host system by following the instructions in the host system technical documentation.
4. Either remove the SAS cable connectors from the internal drives, or remove the shielded cables from the external
drives that you want to migrate.
a. Make sure that pin 1 on the cable matches pin 1 on the connector.
b. Make sure that the SAS cables conform to all SAS specifications.
5. Remove the drives from the first system, and insert them into the drive bays on the second system.
6. Connect the SAS cables to the drives in the second system.
7. Determine the SAS target requirements.
8. Perform a safety check.
a. Make sure that all of the cables are attached correctly.
b. Make sure that the RAID controller is installed correctly.
c. Close the cabinet of the host system.
9. Reconnect the power cords to the system.
10. Turn on the power to the system.
The controller detects the RAID configuration from the configuration data on the drives.
1.7 Hardware Specifications
You can install the 6Gb/s MegaRAID SATA+SAS RAID controllers in a computer with a motherboard that has a PCI
Express slot. The following table describes the hardware configuration features for the 6Gb/s MegaRAID SATA+SAS
RAID controllers.
NOTE When you migrate drives, move only the drives that make up the virtual drive (not all of the drives
in a drive group), so that you do not see an NVRAM mismatch error (providing a configuration is on the
destination controller). The NVRAM mismatch error appears only if you move all of the drives to the
other controller.
