The following table describes the labels in this screen.
Table 7 Storage Manager > Overview > Internal Volumes
LABEL DESCRIPTION
Storage The circular icon displays the overall health state of the NAS.
A green circle with a check mark indicates healthy.
An orange circle with an exclamation mark indicates attention. This appears when a
volume or disk group is degraded. Click Repair to repair it.
An red circle with an exclamation mark indicates danger. This appears when a
volume or disk group is crashed. You cannot recover the volume.
Volume on RAID This section shows the current storage usage for each volume built directly on top of a
RAID. These volumes have higher access performance than volumes on a disk group
but are less flexible in regards to size.
Details include the currently used percentage of the volume.
Shared Folder (Normal) - green on the circle represents the volume’s percentage of
used capacity in a healthy state.
LUN (Normal) - blue on the circle represents the iSCSI LUN’s percentage of used
capacity.
Degraded - orange on the circle represents the volume’s percentage of used
capacity in a degraded state. Degraded means one or more disks has failed but you
can still replace a faulty disk to recover the volume.
Crashed/Full - a red exclamation point represents the volume is in a down state.
Down means you cannot recover the volume. Full means the volume has run out of
space.
Available - gray on the circle represents the volume’s percentage of unused
capacity.
This section also displays the volume’s used capacity, and total capacity available.
Volume on Disk Group This section shows the current storage usage for each volume built on top of a disk
group. You can expand a volume’s size after creation if the disk group has
unallocated space. You can also expand a disk group by adding hard disks.
