3.7 Performing Drive Migration
Drive migration is the transfer of a set of hard drives in an existing
configuration from one controller to another. If you put the hard drives on
a new controller, the controller must have a clear configuration.
Drive migration is the transfer of a set of hard drives in an existing
configuration from one controller to another. If you put the hard drives on
a new controller, the controller must have a clear configuration. To keep
the original configuration, the drives must remain on the same channel
and be reinstalled in the same order as were on the previous controller.
Note: Drive roaming and drive migration cannot be supported at
the same time. The MegaRAID controller can support
either drive roaming or drive migration, but not both at the
same time.
The drives must remain on the same channel and be reinstalled in the
same order as in the original configuration. You can perform online RAID
level migration when you do this. In addition, no reboot is necessary after
capacity expansion.
Perform the following steps to migrate drives:
Step 1. Turn off all power to the system and all hard drives, enclosures,
and system components, then disconnect power cords from the
systems.
Step 2. Open the host systems by following the instructions in the host
system technical documentation.
Step 3. Remove the unshielded, twisted pair, SCSI ribbon cable
connectors from the internal drives or the shielded cables from
the external drives you want to migrate.
◊
Make sure pin 1 on the cable matches pin 1 on the connector.
◊ Make sure that the SCSI cables conform to all SCSI
specifications.
Step 4. Remove the hard drives from the first system and insert them
into drive bays on the second.
Step 5. Connect the SCSI cables to the hard drives in the second system.
Step 6. Determine the SCSI ID and SCSI termination requirements.
