MegaRAID Drive Characteristics
The Mraid2kx.sys driver is 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 Disk Administrator. If you're not familiar with NT Disk
Administrator, refer to the Windows 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.
Adding Capacity to an Array
Adding Capacity under Windows 2000
You can add capacity or a HDD to an existing array only under the following
conditions:
•
The FlexRAID Power Fail Option needs to be enabled
•
Only one logical drive can be configured per array (not per controller)
•
Drives can be added to RAID levels 0, 1, or 5 only
•
New drive(s) have been added to the SCSI bus or subsystem
•
Disk cannot be dynamic; this feature supports Basic Disk only
