Chapter 4 Volume Status
4.1 Volume (Basic Information)
• Allocation
The allocation method for the volume is displayed.
A "-" (hyphen) is displayed when the volume type is other than "TPV" or "FTV".
- Thin
Physical area is allocated to the target area of the volume when a write I/O is received.
- Thick
Physical area is allocated to the whole area of the volume when volumes are created.
• Used Capacity
The used capacity (physically allocated capacity) of volume is displayed with "MB", "GB", or "TB".
A "-" (hyphen) is displayed in the following conditions:
- The volume type is not "TPV" or "FTV"
- Deduplication/Compression Volumes (*1)
*1: The used capacity of the Deduplication/Compression Volumes in the TPP can be determined by checking the
used capacity of the DEDUP_SYS Volume that is created in the TPP. The used capacity of the DEDUP_SYS Vol-
ume approximately corresponds to the total used capacity of the Deduplication/Compression Volumes in the
relevant TPP.
• Used Rate
The volume utilization is displayed between 0% - 100%.
Used Rate = Used Capacity / Capacity
A "-" (hyphen) is displayed in the following conditions:
- The volume type is not "TPV" or "FTV"
- Deduplication/Compression Volumes (*1)
*1: The used rate of the Deduplication/Compression Volumes in the TPP can be determined by checking the used
rate of the DEDUP_SYS Volume that is created in the TPP. The used rate of the DEDUP_SYS Volume approxi-
mately corresponds to the total used rate of the Deduplication/Compression Volumes in the relevant TPP.
Note that the capacity reduction rate for the TPP due to the Deduplication/Compression function can be
checked in the [Thin Provisioning Pool] screen. Refer to
(page 325)
• Threshold
The threshold for monitoring the volume utilization is displayed between 1% - 100%.
If the "Used Rate" value exceeds the "Threshold", a Host Sense Key Code Qualifier is notified.
A "-" (hyphen) is displayed in the following conditions:
- The volume type is not "TPV" or "FTV"
- Deduplication/Compression Volumes or Deduplication/Compression System Volumes
• The threshold for TPPs can be checked in the [Threshold] screen. Refer to
Provisioning Pool)" (page 334)
• The threshold for FTRPs can be checked in the [Flexible Tier Pool] screen. Refer to
Pool (Basic Information)" (page 340)
