iSCSI CHAP authentication: iSCSI CHAP (Challenge-Handshake Authentication Protocol) provides enhanced security by requiring a username and password for authentication before establishing a connection. Users can configure iSCSI CHAP authentication using iscsiadm.

iSCSI boot configuration: iscsiadm can be used to configure iSCSI boot settings, allowing a server to boot from an iSCSI target. This feature is particularly useful in diskless server environments or for centralized storage management.

Session and connection management: iscsiadm provides options to manage iSCSI sessions and connections, including listing active sessions, logging in to a target, logging out from a target, and modifying connection parameters.

Performance tuning: Users can use iscsiadm to optimize iSCSI performance by adjusting parameters such as the maximum data transfer size, the number of outstanding commands, and the timeout values.

Multipath support: iscsiadm supports multipathing for iSCSI connections, allowing multiple paths to a target for increased reliability and performance. Users can configure multipath settings using iscsiadm to ensure seamless failover and load balancing.
