User Guide

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.

3. Boot the system and import the foreign configuration that is detected. You can do one of the

following:

• Press <F> to automatically import the foreign configuration.

• Enter the BIOS Configuration Utility and navigate to the Foreign Configuration View.

NOTE: For more information on accessing the BIOS Configuration Utility, see the topic

Entering The BIOS Configuration Utility.

NOTE: For more information on Foreign Configuration View, see the topic Foreign

Configuration View.

4. Exit the BIOS Configuration Utility and reboot the system.

5. Ensure that all the latest drivers for the PERC H710, H710P, or H810 card (available at

support.dell.com) are installed.

For more information, see the topic Drive Installation.

Virtual Disk Write Cache Policies

NOTE: PERC H310 only supports Write-Through mode.

The write cache policy of a virtual disk determines how the controller handles writes to the virtual disk.

Write-Back and Write-Through are the two write cache policies that can be set on virtual disks

individually.

All RAID volumes are presented as Write-Through to the operating system (Windows and Linux)

independent of the actual write cache policy of the virtual disk. The PERC cards manage the data in

cache independently of the operating system or any applications.
