Migrating SCSI Virtual Disks to Another System
Migrating SAS Virtual Disks to Another System
This section describes how to move physical and virtual disks from one system to another.
Required Conditions
This section applies to PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, CERC ATA100/4ch, PERC 5/E and
PERC 5/i, and SAS 5/iR controllers
After some planning and preparation, it is possible to migrate physical and virtual disks from one controller, enclosure or server to another. You can perform
physical and virtual disk migration on PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, CERC ATA100/4ch, PERC 5/E and PERC 5/i, and SAS 5/iR controllers as
long as the following conditions are met.
General Conditions for SCSI and SAS Controllers
l Virtual disks can only be migrated to a controller that is using the same technology. For example, virtual disks on a SCSI controller must be migrated to
a SCSI controller and virtual disks on a SAS controller must be migrated to a SAS controller. See "RAID Controller Technology: SCSI, SATA, ATA, and SAS"
for more information.
l When moving an enclosure, both SCSI and SAS controllers require that you power down the enclosure and the server before moving the enclosure.
SCSI Controller Conditions
l PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di virtual disks cannot be migrated to a PERC 2/SC or PERC 2/DC controller. PERC 2/SC
and PERC 2/DC virtual disks can be migrated to a PERC 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, or 4e/Di controller.
l A virtual disk cannot be migrated between the PERC 3/Si, PERC 3/Di, CERC SATA1.5/6ch, and CERC SATA1.5/2s controller family and the PERC 3/SC,
3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, and CERC ATA100/4ch controller family.
l On SCSI controllers, a virtual disk cannot be migrated from one controller to another unless the receiving controller's configuration has been cleared.
l When moving the physical disks on a SCSI controller from one enclosure to another, the SCSI ID for each disk must remain the same. See "RAID
Controller Technology: SCSI, SATA, ATA, and SAS" for more information.
l When moving the physical disks from one enclosure to another or when moving an external enclosure from one server to another, the enclosure must
be connected to the same connector number on the controller as in the original condition.
l In the case where a virtual disk consists of physical disks on multiple connectors, each physical disk must be migrated to an enclosure that is connected
to the same connector number that the physical disk or enclosure was originally connected to.
SAS Controller Conditions
l On SAS controllers, you can migrate a virtual disk by moving the physical disks from one controller to another and then importing the foreign
configuration on the receiving controller. See "Foreign Configuration Operations" for more information.
l When moving an enclosure on a SAS controller, you can move the enclosure to any connector number and then import the foreign configuration on the
receiving controller. See "Foreign Configuration Operations" for more information.
Migrating SCSI Virtual Disks to Another System
NOTE: The current version of Storage Management does not support the PERC 2, 2/Si, 2/SC, or 2/DC controllers.
