→ Applies to: SynetoOS 6.0.3 and above

IMPORTANT
Licensing: A valid, active license applied to your SynetoOS node enabling the iSCSI storage feature.

PREREQUISITES
Storage allocation — a LUN/volume configured on the remote NAS, properly mapped and set to accept incoming initiator connections
NAS-level redundancy — data redundancy (RAID/ZFS mirror) is already configured and managed on the NAS; SynetoOS will not add redundancy on top of the presented LUN
Network connectivity — a valid Portal IP address and a working network route between the SynetoOS host and the remote iSCSI target on TCP port 3260
Initiator IQN — the unique IQN (iSCSI Qualified Name) of your SynetoOS host, whitelisted on the remote target to authorize access
Target IQN — the exact IQN of the target storage array/pool you intend to connect to
CHAP credentials (optional) — the CHAP username and secret matching the target server's configuration, if authentication is enabled
