In addition, FastPath-capable virtual disks are characterized by the following:

•The presence of CacheCade virtual disks on a controller disables the FastPath capability of all eligible HDD virtual disks. Eligible SSD virtual disks are still FastPath-capable.

•Secured virtual disks are not FastPath-capable.

•The Physical Disk Power Management feature is not applicable to FastPath-capable virtual disks.

•The addition or removal of a redundant path does not affect the FastPath-capability of virtual disks.

Virtual Disk Migration

The PERC H710, H710P, and H810 cards support migration of virtual disks from one controller to another without taking the target controller offline. The controller can import RAID virtual disks in optimal, degraded, or partially degraded states. You cannot import a virtual disk that is in an offline state. Disk migration pointers:

•Supports migration of VDs from PERC H700 and H800 to PERC H710P and H810

•Supports migration of volumes created within H710, H710P, or H810

•Supports migration of volumes created on H310 to H710, H710P, or H810

•Does not support migration from H700 or H800 to H310

•Does not support migration from H710, H710P, or H810 to H310

•Does not support backward migration from H310, H710, H710P, H810 to H800 and H700

NOTE: The source controller must be offline prior to performing the disk migration.

NOTE: Disks cannot be migrated to older revisions or generations of the PERC cards.

NOTE: Non-RAID disks are supported only on the PERC H310 controller. Migration to any other PERC product is not supported.

NOTE: Importing secured virtual disks is supported as long as the appropriate key (LKM) is supplied or configured.

When a controller detects a physical disk with an existing configuration, it flags the physical disk as foreign, and generates an alert indicating that a foreign disk was detected.

CAUTION: Do not attempt disk roaming during RLM or OCE. This causes loss of the virtual disk.

Migrating Virtual Disks

To migrate virtual disks from PERC H700 or H800 to PERC H710, H710P, or H810:

1.Turn off the system.

2.Move the appropriate physical disks from the PERC H700 or H800 card to the PERC H710, H710P, or H810 card.

NOTE: If you are replacing your PERC H700 or H800 with a PERC H710, H710P, or H810 card, see the Owner’s Manual of your system at support.dell.com/manuals.
