Information

 

 

 

 

DOS ASPI

 

 

MEGASPI.SYS, the MegaRAID DOS ASPI manager, uses 6 Kbytes of system

 

 

 

memory once it is loaded.

 

 

 

CD drives under

 

At this time, copied CDs are not accessible from DOS even after loading

DOS

 

 

MEGASPI.SYS and MEGACDR.SYS.

 

 

 

Physical drive errors

 

To display the MegaRAID Manager Media Error and Other Error options, select

 

 

 

the Objects menu, then Physical Drive. Select a physical drive and press <F2>.

 

 

 

The windows displays the number of errors.

 

 

 

A Media Error is an error that occurred while actually transferring data. An

 

 

 

Other Error is an error that occurs at the hardware level because of a device

 

 

 

failure, poor cabling, bad termination, signal loss, etc.

 

 

 

 

Virtual sizing

 

 

The virtual sizing option enables RAID expansion. Virtual sizing must be

 

 

 

enabled to increase the size of a logical drive or add a physical drive to an

 

 

 

existing logical drive.

 

 

 

Run the BIOS Configuration Utility by pressing <Ctrl><M> to enable virtual

 

 

 

sizing. Select Objects, then Logical Drive. Next, select View/Update

 

 

 

Parameters, then set virtual sizing to Enabled.

 

 

 

 

BSD Unix

 

 

We do not provide a driver for BSDI Unix. MegaRAID SCSI 320-0 does not

 

 

 

support BSDI Unix.

 

 

 

Multiple LUNs

 

MegaRAID SCSI 320-0 supports one logical unit number (LUN) per each target

 

 

 

ID. No multiple LUN devices are supported.
