Using the RAID GUI
2-22
• Detailed logical disk information
Click to display a complete list of logical disk information. You will see the following details.
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.
• Delete volumes
Select the volume(s) you want to delete and click Delete. To delete all LUNs of volx, check the ‘Force to delete LUN
mapping(s)’ box. All access to the volume will be stopped.
• DG ID
• LD ID
• UUID
• Created Time and Date
• LD Read Algorithm
• Alignment Offset (sector)
• Write Cache Status
• Write Cache Setting
• Write Sorting
• Read Ahead Policy
• Read Ahead Multiplier
• Read Logs
• Member State
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.
