Drives will be listed in the table of “View and Edit SCSI Drives.”
Use arrow keys to scroll the table. You may first examine whether
there is any drive installed but not listed here. If there is a drive
installed but not listed, the drive may be defective or not installed
correctly, please contact your RAID supplier.
IMPORTANT!
•
Drives of the same brand/model/capacity might not have the same block
number.
• The basic read/write unit of a hard drive is block. If members of a logical
drive have different block numbers (capacity), the smallest block number will
be taken as the maximum capacity to be used in every drive. Therefore, use
drives of the same capacity.
• You may assign a Local/Global Spare Drive to a logical drive whose
members has a block number equal or smaller than the Local/Global Spare
Drive but you should not do the reverse.
