5.  Select the UDV for snapshot by checking the front square and 

click

.  

6.  A snapshot UDV is now created with the date and time stamp of when 

the image was taken. 

7.  Attach Bus ID, SCSI, ID, and LUN to the snapshot UDV. Please see 

section 5.3 for more detail on attaching the IDs and LUN. 

 

 

Figure 5.7.1 

(Figure 5.7.1: No.1 is a RAID 0 UDV. Snapshot space set to 56GB. No.2 is a snapshot UDV 

taken on 07/24 15:12:21.) 

 
Snapshot function may have some limits in the current version as described 
below: 
 

1.  Snapshot function is incremental. For example: three snapshots have 

been taken and named as “snap1” (first), “snap2”, “sanp3” (last). When 
deleting “snap2”, both of “snap1” and “snap2” will be deleted because 
“snap1” are related to “snap2”. 

2.  The max number of snapshots is 8. 
3.  If snapshot space is full, snapshot UDVs will fail and become unusable. 
4.  Snapshot UDVs can not migrate with the VG and will be deleted when 

migration is executed. 

 
 

5.8 Auto 

snapshot 

 
Snapshot function can be setup to automatically take images of a UDV at 
specified period of time or intervals. Please follow these instructions to setup 
automatic snapshot. 
 

1. Enter 

Volume config

. 

2. Enter 

User data volume

. 

3.  Create a snapshot space. Please see section 5.7 for more detail.
