Megaraid Drive Characteristics; Deleting Logical Drives - LSI SCSI 320-0 Configuration

MegaRAID Drive Characteristics

Mraid35x.sys Driver versions 2.19 and above are capable of reporting newly
configured logical drives to Windows NT Disk Administrator without rebooting
the operating system.
After creating the drive arrays and logical drives in Power Console Plus,
configure the new logical drive(s) in the NT Disk Administrator. If you're not
familiar with NT Disk Administrator, refer to the Windows NT Operations
manual.
There are rules that need to be followed for proper operation:
•
If the controller's configuration is reset, any logical drives created after the
reset will not be seen properly, and the operating system must be rebooted.
•
If you delete a logical drive, the capacity of the next logical drive that you
add will not be seen properly in Disk Administrator. Disk Administrator
will see the capacity of the deleted logical drive. You must reboot the
operating system to display the proper capacity of the newly configured
logical drive.
•
If Virtual Sizing is enabled during the creation of the logical drive, the
operating system must be rebooted. Virtual Sizing is reported to Disk
Administrator by the firmware, not the driver. The driver reports the size;
however, it is valid only on operating system load time.

Deleting Logical Drives

Logical drives can be deleted, but only the last logical drive that was created can
be deleted. Once a logical drive is deleted, the capacity of the next logical drive
that you add will not be seen correctly in Disk Administrator until the operating
system is rebooted.
