The Virtual Disk screen displays any existing Virtual Disks and
allows you to create and delete Virtual Disks. For instructions on
how to create a Virtual Disk, see Section 8.3.2.
The following information is displayed:
Virtual Disk Column Descriptions
No. The Virtual Disk number. Hover your mouse cursor over
the button below the Virtual Disk number for configuration
options.
Name The name of the Virtual Disk.
Total The total capacity of the Virtual Disk. Can be displayed in
MB or GB.
Write The write status of the Virtual Disk.
• WT → Write Through
• WB → Write Back
• RO → Read Only
Priority Displays the priority that the RTX Secure will give to RAID
activities (rebuild, initialization) versus priority given to
file transfers.
• HI → High Priority
• MD → Medium Priority
• LO → Low Priority
BG Rate Background Task Priority. 4 / 3 / 2 / 1 / 0 → The default
value is 4. The higher the number, the more priority will be
given to background input/output.
Status The status of the Virtual Disk.
• Online → The Virtual Disk is online.
• Offline → The Virtual Disk is offline.
• Initiating → The Virtual Disk is being initialized.
• Rebuild → The Virtual Disk is being rebuilt.
• Migrate → The Virtual Disk is being migrated.
• Rollback → The Virtual Disk is being rolled back.
• Parity Checking → The Virtual Disk is undergoing
a parity check.
Type Indicates that the Virtual Disk is part of a RAID Group.
Health The health of the Virtual Disk.
• Optimal → The Virtual Disk is working well and

removed from the RTX Secure.
• Failed → The RAID Group that the Virtual Disk
belongs to has failed and cannot recover from data

ity check, the health status will change to Optimal.
R% Shows the percentage completed of an initialization or
RAID rebuild.
RAID Displays the RAID level.
#LUN The number of Logical Unit Numbers that are attached to
the Virtual Disk.
RG Name The name of the RAID Group to which the Virtual Disk
belongs.
