Topic Information
DOS ASPI MEGASPI.SYS, the MegaRAID DOS ASPI manager, uses 6 Kbytes of system
memory once it is loaded.
CD drives under
DOS
At this time, copied CDs are not accessible from DOS even after loading
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.
