Benefits of the ServeRAID M1115 Controller 1-15
Step 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.
Note: When you migrate drives, move only the disks that make
up the virtual disk (not all of the physical disks in an array),
so that you do not have 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.
Step 2. Turn off the power to the server and all physical disks,
enclosures, and system components. Disconnect the power
cords from the systems.
Step 3. Open the host system, following the instructions in the host
system technical documentation.
Step 4. Remove the SAS cable connectors from the internal 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.
Step 5. Remove the physical disks from the first system, and insert
them into drive bays on the second system.
Step 6. Connect the SAS cables to the physical disks in the second
system.
Step 7. Determine the SAS target requirements.
Step 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.
Step 9. Reconnect the power cords to the system.
Step 10. Turn on the power to the system.
The controller detects the RAID configuration from the
configuration data on the drives.
