Updating Your MD3000 to Support

SATA II Disks

SATA Support Available in MD3000 Storage

Arrays

MD3000 storage arrays now support a total of 45 3.5” SAS and/or SATA II

physical disks. The enclosure can contain a mixture of SAS and SATA physical

disks; however, a disk group must consist of either SAS or SATA physical

disks. If SAS disk groups and SATA II disk groups are configured in the same

storage array, a hot spare must be available for each type and of equal or

greater size than the disk group member drives. Both SAS and SATA physical

disks are hot-pluggable, allowing you to remove and insert disks without

shutting down your enclosure.

NOTE: SATA I Physical disks are not supported in the MD3000 storage array

enclosure.

NOTE: Please follow the included guidelines to insert or remove physical disks

from the enclosure.

This document covers the steps you must perform to upgrade your MD3000

storage array to support SATA physical disks.

Who Needs to Perform These Steps?

You only need to perform these steps if your storage array controller firmware

or Modular Disk Storage Manager versions are earlier than those shown in

Table 1-1.

You can check the MD Storage Manager version by going to the Support tab

and clicking About Modular Disk Storage Manager. You can also determine

the Controller Firmware Version by going to Support

Upgrading Supported SATA Physical Disks in an MD1000 Attached to a

PERC Adapter

NOTE: This is the Dell recommended method of upgrading the firmware on

physical disks that are not supported for the MD3000 without a firmware upgrade.

Before migrating SATA physical disks currently in an MD1000 expansion

enclosure to an MD3000 storage array enclosure, perform the following steps:

Stop all I/O to and from the enclosure

Download the SATA physical disk firmware utility from the

Drivers and

Downloads

section of

support.dell.com

NOTE: Refer to the MD3000 Support Matrix on support.dell.com for minimum

physical disk firmware requirements. Using physical disks with mismatched

firmware versions may produce unknown behavior.

included with the utility.

Select the appropriate file for your SATA physical disk vendor model.

Upgrade each SATA physical disk within the MD1000 with the latest

firmware.

Preparing an MD1000 Attached to a Dell PERC Adapter before

Connecting It to an MD3000

Use this procedure if your MD1000 is now directly attached to and configured

on a Dell PERC system and you wish to connect it to your MD3000. Data

from virtual disks created on a PERC SAS controller cannot be directly

migrated to an MD3000 or to an MD1000 expansion enclosure connected to

an MD3000.

NOTE: If an MD1000 that was previously attached to PERC SAS controller is used

as an expansion enclosure to an MD3000, the physical disks of the MD1000

enclosure will be re-initialized and data will be lost. All data on the MD1000 must be

backed up before attempting the expansion.

Perform the following steps to attach a previously configured MD1000

expansion enclosure to the MD3000:

Back up all data on the MD1000 enclosure(s).
