Configuration data is saved in both nonvolatile random access memory
(NVRAM) on the RAID controller and on the hard drives attached to the
controller. This maintains the integrity of the data on each drive, even if
the drives have changed their target ID.
Note: In a clustering environment, drive roaming is supported
within the same channel only. Drive roaming between
channels in a cluster is not supported.
Note: Drive roaming from multiple controllers to a cluster-configured
controller is not supported.
Perform the following steps to use drive roaming:
Step 1. Turn off all power to the system and all hard drives, enclosures,
and system components, then disconnect power cords from
the system.
Step 2. Open the host system 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 move.
- 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. Connect the hard drives to different connectors on the cable.
Step 5. Determine the SCSI ID and SCSI termination requirements.
Note: The default for SCSI termination is onboard SCSI termination
enabled. See the MegaRAID 320 Storage Adapters User’s
Guide for more information about SCSI termination.
Step 6. Perform a safety check.
◊
Make sure all cables are properly attached.
◊
Make sure the RAID controller is properly installed.
◊
Close the cabinet of the host system.
◊
Turn power on after completing the safety check.
Step 7. Power on the system.
The controller then detects the RAID configuration from the
configuration data on the drives.
