2. Once the iSCSI driver is installed the IP host will proceed with a discovery process for iSCSI storage devices as follows The iSCSI driver requests available iSCSI targets from the SR2122 The SR2122 sends available iSCSI target names to the IP host The IP host logs in to the iSCSI targets The SR2122 accepts the IP host login and sends target identifiers The IP host queries targets for device information Targets respond with device information moe pa o oo EQ uq The IP host creates a table of internal devices The HP StorageWorks iSCSI Driver for Microsoft Windows 2000 and Windows 2003 uses Windows 2000 network services to connect to iSCSI remote target nodes that are defined using the iSCSI control panel applet Using the Status button of the iSCSI Configuration Control applet can retrieve status of the iSCSI connections to the remote target nodes and targets Each responding remote target will show up with its IP address connect state and target name or alias The possible connect states are Table 5 Possible Connect States NOTINIT TCP connection CLOSED iSCSI not initialized UP TCP connection ESTABLISHED iSCSI not initialized DOWN TCP connection CLOSED iSCSI down LOGIN TCP connection ESTABLISHED proceeding with iSCSI login sequence ACTIVE TCP connection ESTABLISHED iSCSI active BREAK TCP connection CLOSING iSCSI going down WAIT TCP connection ESTABLISHED iSCSI waiting

5. Linux is unable to find a driver to associate with a SCSI device node that the iSCSI daemon is opening as part of it s symlink creation process To prevent these messages the SCSI device nodes with no associated high level SCSI driver can be removed The iSCSI driver automatically maintains a bindings file var iscsi bindings This file contains persistent bindings to ensure that the same iSCSI bus and target id number are used for every iSCSI session to a particular iSCSI TargetName even when the driver is repeatedly restarted This feature ensures that the SCSI numbers in the device symlinks described above will always map to the same iSCSI target Note that because of the way Linux dynamically allocates SCSI device nodes as SCSI devices are found the driver does not and cannot ensure that any particular SCSI device node e g dev sda will always map to the same iSCSI TargetName The symlinks described in the section on Device Names are intended to provide a persistent device mapping for use by applications and fstab files and should be used instead of direct references to particular SCSI device nodes If the bindings file grows too large lines for targets that no longer exist may be manually removed by editing the file Manual editing should not normally be needed since the driver can maintain up to 65535 different bindings iSCSI SR2122 Storage Router Getting Started Guide 43 Serving Storage to the iSCSI Initiators from the SR2122
