Using the RAID GUI
2-32
2.6.5 Volumes
This feature allows you to create, delete, and modify your volume
settings. RAID 30/50/60 are supported by creating striping volumes over
RAID 3/5/6 logical disks.
• Create volumes
Click Create to add a new volume, where up to a maximum of 32
volumes can be created. Specify the following options for the
configuration.
VOL ID Select a VOL ID from the drop-down menu.
Name Use the system default name as volx. ‘x’ is the VOL
identifier.
OR
Uncheck the ‘Use system default name’ box and
enter the name in the Name field. The maximum
name length is 63 bytes.
LD Level Select a RAID level to filter a list of member LDs.
LD Owner
Controller
This option is only available when the redundant-
controller system is in use. Select the owner
controller of the member LDs. Only the LDs whose
owner controller are equal to the specified will be
filtered out in "Member LDs".
Member LDs Select the LDs to be grouped.
Preferred
Controller
This option is only available when the redundant-
controller system is in use. Select the preferred
controller to be in charge of managing and
accessing the volume.
Stripe Size (KB) 4 / 8 / 16 / 32 / 64 / 128 / 256 / 512
The stripe size must be larger than or equal to the
cache unit size.
Alignment
Offset (sector)
Set the alignment offset for volume starting sector
to enhance the controller’s performance. For
Windows OS, it is suggested to set the alignment
offset at sector 63.
Note
1. All logical disks must be in the same RAID level.
2. No two logical disks can be in the same disk group.
3. None of the logical disks can be used by other volumes.
4. None of the logical disks can be bound to any LUNs.
5. All logical disks must be in the optimal state.
6. All disk groups of the logical disks must belong to the same owner
controller.
