Use “Expand RAID Set’ function to add disk to a RAID set. The additional capacity
can be used to enlarge the last volume set size or to create another volume set. The
“Modify Volume Set” function can support the “Volume Modification” function. To
expand the last volume set capacity , move the cursor bar to the “ Capacity” item
and entry the capacity size. When finished the above action, press the
ESC
key and
select the
Yes
option
to complete the action. The last volume set starts to expand its capacity.
To expand an existing volume noticed:
•
Only the last volume can expand capacity.
•
When expand volume capacity, you can’t modify stripe size or modify RAID revel
simultaneously.
•
You can expand volume capacity, but can’t reduce volume capacity size.
•
After volume expansion, the volume capacity can't be decreased.
For greater 2TB expansion:
•
If your system installed in the volume, don't expand the volume capacity greater
2TB, currently OS can’t support boot up from a greater 2TB capacity device.
•
Expand over 2TB used LBA64 mode. Please make sure your OS supports LBA64
before expand it.
Volume Set Migration
Migrating occurs when a volume set is migrating from one RAID level to another,
when a volume set strip size changes, or when a disk is added to a RAID set.
Migration status is displayed in the volume state area of the “Volume Set
Information” screen.
Check Volume Set
To check a volume set from a RAID set:
(1). Click on the “Check Volume Set” link.
(2). Click on the volume set from the list that you wish to check. Tick on “Confirm The
Operation” and click on the “Submit” button. Use this option to verify the correctness of the
redundant data in a volume set. For example, in a system with dedicated parity, volume
set check means computing the parity of the data disk drives and comparing the results to
the contents of the dedicated parity disk drive. The checking percentage can also be viewed
by clicking on “RaidSet Hierarchy” in the main menu.
Stop VolumeSet Check
Use this option to stop the “Check Volume Set function”.
Physical Drive
Choose this option to select a physical disk from the main menu and then perform the
operations listed below.
Create Pass Through Disk
To create pass through disk, move the mouse cursor to the main menu and click on the
“Create Pass Through” link. The “Select the IDE Drive For Pass Through” screen appears.
A pass through disk is not controlled by the RM16_EX8 raid engine firmware, it cannot
be a part of a volume set. The disk is available to the operating system as an individual
disk. It is typically used on a system where the operating system is on a disk not
controlled by the RAID firmware. The user can also select the Cache Mode, Tagged
Command Queuing, SCSI channel/SCSI_ID/SCSI_LUN for this pass through disk.
