Features
Physical disk roaming The controller supports moving a physical disk from one
backplane slot or cable connection to another (on the same
controller). The controller automatically recognizes the
repositioned physical disk and logically places it in the proper
order.
WARNING:
A virtual disk is lost if you perform disk
roaming while an OCE is running at Storage Management.
NOTE:
For more information on how to open the system and
add parts, see the Hardware Owner’s Manual, available on the
Dell Support website at support.dell.com/manuals.
Perform the following steps for physical disk roaming:
NOTE:
These steps do not apply to systems that have a
backplane with hot-swap capability.
1
Turn off the power to the system, physical disks, and system
components.
2
Disconnect the power cables from the system.
3
Move the physical disks to different slots on the backplane
or to different cable connections.
4
Perform a safety check. Make sure the physical disks are
inserted properly.
5
Connect the power cables and power up the system.
NOTE:
The controller detects the RAID configuration from the
configuration data on the physical disks.
