Drive Migration
Drive migration is the transfer of a set of drives in an existing
configuration from one controller to another. The drives must remain on
the same channel and must be reinstalled in the same order as in the
original configuration. The controller to which you migrate the drives
cannot have an existing configuration.
Note:
Only complete configurations can be migrated
automatically; however, you can migrate virtual disks
manually.
Note:
Drive roaming and drive migration cannot be supported at
the same time.
Follow these steps to migrate drives:
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.
