Managing Your Storage Enclosure - Dell PowerVault MD1000 Hardware Owner's Manual

To change to either mode from a previous configuration:
1 Back up all data contained in the enclosure and store the backed up data in a secure location.
2 When changing from unified mode to split mode, remove any virtual disk configurations that span slot
ranges 0-6 and 7-14. For more information, see your Server Administrator documentation.
NOTE:
When changing from split mode to unified mode, some virtual disks may appear as foreign if the
configuration was not deleted before powering the enclosure back on. These disks must be imported via Server
Administrator or the PERC 5/E Ctrl-R BIOS utility before they can be used.
NOTE:
If changing from unified mode to split mode, keep in mind that daisy chaining of enclosures is not supported
in split mode.
3 Power down the server.
4 Power down the enclosure by turning off both power supply/cooling fan modules.
5 Change the position of the enclosure mode switch (see Figure 1-7).
6 Rearrange the disks in the enclosure as necessary.
7 Power on the enclosure by turning on both power supply/cooling fan modules.
8 Power on the server.
9 Re-create any virtual disks within the enclosure, if necessary.

Managing Your Storage Enclosure

Disk storage within the enclosure can be configured using either the PERC 5/E Ctrl-R BIOS firmware or
Server Administrator. For optimal management and serviceability of your enclosure, Dell recommends use
of Server Administrator.
NOTE:
Online configuration, enclosure status, and active event notification is supported with Server Administrator
version 4.5.1 or later only.
Dell OpenManage™ Server Assistant provides a comprehensive server/storage management solution with
an integrated graphical view and command line interface. It enables online configuration and
management for both server-internal storage and externally attached storage.
Server Assistant obtains information about physical storage devices, disk enclosures, virtual disks/RAID
arrays, and logical devices and displays the information in both physical and logical views. These views
are accessed via a storage controller icon or a textual link. From the Server Assistant console, you can
create and manage RAID storage configurations, display storage information, customize event reporting,
and view logged events. Logged events can also be used to create alerts containing detailed enclosure
(logical and physical) device status. From the Server Assistant console, you can also run diagnostics and
perform firmware downloads to the enclosure.
For more information, see the Server Assistant documentation for more details.
