TeraStation III iSCSI User Manual
Formatting a drive or array will erase all volumes on the drive or array. After formatting a
disk from Settings, you must allocate a partition and format it before it is usable. Use Disk
Management on Windows to allocate a partition and format it.
Checking Encryption before formatting encrypts the drive or array with 128 bit AES encryption.
Only the TeraStation will be able to read the disk after that. To unencrypt the hard drive,
uncheck Encryption and format it again.
Before physically removing a drive from the TeraStation, select the drive and click Remove Disk
to dismount the disk. It's then safe to remove it.
replacement drive without restarting the TeraStation.
By default, the TeraStation is in RAID 5 mode. You may configure any of the following RAID
modes: RAID 5, RAID 1, RAID 10, and RAID 0.
To configure a RAID array, check the hard drives to use, select RAID mode, and click Create RAID
Array.
• To build a RAID 1 array, check 2 drives.
• To build a RAID 10 or RAID 0 array, check all drives.
• To build a RAID 5 array, check 3 or 4 drives.
• To delete an array, click Delete RAID Array.
Changing RAID modes will erase all data on the array. Back up any important data before
changing the RAID mode.
If you have a leftover drive after building a RAID 5 array with 3 drives, or a RAID 1 array, it can
be set as a hot spare by clicking Set to spare-disk. Click Set to normal disk to change it back to a
normal drive.
• RAID Array Error Detection Response:
With a RAID 1, RAID 5, or RAID 10 array, you may choose to have the system shut down
automatically if an error is detected. This feature is not available for RAID 0 arrays or disks in
normal mode. By default, this is set to Shut Down.
• Boot with iSCSI service:
After an error occurs, the iSCSI service may be enabled or disabled at the next boot. By default,
it will be enabled.
• RAID Array check speed:
Select the speed of the RAID Scan from the following:
High: 10 hours per 1 TB RAID Array
Normal: 20 hours per 1 TB RAID Array
Low: 100 hours per 1 TB RAID Array
