QNAP QTS 4.5 Series User Manual

The iSCSI Target Creation Wizard window opens.
3. Click Next.
4. Specify a target name.
QTS appends the specified name to the iSCSI qualified name (IQN). IQNs are unique names used to
identify targets and initiators.
• Valid characters: 0 to 9, a to z, A to Z
• Length: 1 to 16 characters
5. Optional: Specify a target alias.
An alias enables you to identify the target more easily on the initiator.
• Length: 1 to 32 characters
• Valid characters: 0 to 9, a to z, A to Z, underscore (_), hyphen (-), space ( )
6. Optional: Select Allow clustered access to this target.
When enabled, multiple iSCSI initiators can access this target and its LUNs simultaneously.
Warning
To prevent data corruption, the initiators and LUN filesystems must all be cluster-aware.
7. Optional: Enable CRC checksums.
Initiators and targets communicate over TCP connections using iSCSI protocol data units (PDU). The
sending device can send a checksum with each PDU. The receiving device uses this checksum to
verify the integrity of the PDU, which is useful in unreliable network environments. There are two
checksum types, which can be enabled separately.
Checksum Type Description
Data Digest The checksum can be used to verify the data portion of the PDU.
Header Digest The checksum can be used to verify the header portion of the
PDU.
8. Click Next.
9. Optional: Enable CHAP authentication.
An initiator must authenticate with the target using the specified username and password. This provides
security, as iSCSI initiators do not require a NAS username or password.
• Username
• Length: 1 to 128 characters
• Valid Characters: 0 to 9, a to z, A to Z
• Password
• Length: 12 to 16 characters
• Valid characters: 0 to 9, a to z, A to Z
10. Optional: Enable mutual CHAP authentication.
Both the initiator and the target must authenticate with each other for additional security. First, the
initiator authenticates with the target using the CHAP authentication username and password. Next, the
target authenticates with the initiator using the mutual CHAP username and password.
