General System Configuration

6 As disks are added, the Virtual Disk Size field will change to reflect the size of the new virtual

disk. There are several limitations when creating an IM virtual disk:

•

All disks must be either SAS or SATA physical disks. A mixture of SAS and SATA drives is
not supported

•

Disks must have 512-byte blocks and must not have removable media.

•

There must be 2 physical disks in an IM virtual disk.

7 Press and then select Save changes when the virtual disk has been fully configured.
8 Press to confirm that existing data will be lost with the creation of the virtual disk.

The Configuration Utility will pause while the virtual disk is being created.

NOTE:

IM provides protection against the failure of a single physical disk. When a disk fails, the

physical disk can be replaced and the data re-mirrored to the physical disk, maintaining data
integrity.

Additional Integrated Mirroring Guidelines

•

The hard-drive status indicator does not display any status information until after the
operating system driver initialization has occurred. To check for status information of a hard
drive prior to operating system load, use during POST. During normal
operation, the status indicator is off.

NOTE:

The hard-drive activity indicator functions normally before and after the operating system driver

initialization.

•

Any replacement drives should be blank and not previously configured.

•

You should replace hard drives in an integrated-mirror configuration with drives of the same
capacity.

•

After removing a hard drive in a hot-pluggable environment, wait at least 30 seconds prior
to installing the new hard drive.

Connecting a USB Drive, Keyboard, and Mouse to the Server
Module Front Panel

If you need to connect a USB drive (DVD-ROM, CD-ROM, or diskette drive), USB keyboard, and
USB mouse to the server module front panel, connect a powered USB hub to one of the two front
panel USB connectors, and then connect the drive, keyboard, and mouse to the powered USB hub.

NOTE:

The optional DVD-ROM drive requires two USB 2.0 ports.

Installing an Operating System

NOTICE:

If you install an operating system on a server module and your system uses an Avocent Digital

Access KVM module, you must connect the monitor to the KVM module rather than the server module
front panel.
