E. Installation steps for large volume (over 2TB)
Introduction:
This iSCSI RAID subsystem is capable of supporting large volumes (>2TB). When
connecting the iSCSI RAID system to host/server with 64bit OS installed, the
host/server is inherently capable for large volumes from the 64bit address. On the
other side, if the host/server is installed with 32bit OS, user has to change the block
size to 1KB, 2KB or 4KB to support volumes up to 4TB, 8TB or 16TB, for the 32bit
host/server is not LBA (Logical Block Addressing) 64bit supported. For detailed
installation steps, please refer to following steps below.
Step 1:
Configure target
1.
Prepare the hard drivers whose total capacity will be over 2TB. Follow the
example in chapter 3 to create a RG/VD. Then attach LUN.
NOTE: If the OS is 64bit, user can set the block size to any
available value. If the OS is 32bit, user must change the block size
to larger values than 512B. There will be a confirmation pop-up
message when VD size is over 2TB.
In the figure above, choose “OK” for 64bit OS, choose “Cancel” for 32bit
OS, this step will change block size to 4K automatically.
2.
Move the mouse pointer to the gray button next to the VD number; click
“More information”
. Look at the block size; 512B for 64bit OS setting, 4K
for 32bit OS setting.
