Description The iscsi-initiator-utils packages provide the server daemon for the Internet Small Computer System Interface (iSCSI) protocol, as well as the utility programs used to manage it. el7 I used discovery mode to make a connect to a Share box. iSCSI stands for Internet Small Computer Systems Interface, IP-based storage, works on top of internet protocol by carrying SCSI commands over IP network. Here you will find RHEL 7 instructions to configure a system as either an iSCSI target or initiator that persistently mounts an iSCSI target. I'm using IET iscsi target on 2 CentOS 4.
