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 <C> and then select
Save changes
when the virtual disk has been fully configured.
8
Press <F3> 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 <Ctrl><C> 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.
