Can two computers connect to the same iSCSI target?
The short answer to the first part of the question is yes. In the diagram, multiple hosts are, indeed, connecting to a single iSCSI array. The hosts may be connecting to different individual LUNs/targets or multiple hosts may be connecting to the same target.
How do I create an iSCSI target in openfiler?
Configure iSCSI Target in Openfiler:- – Go to Volumes Tab, Click on iSCSI Target in right panel. – Click on Target Configuration. You will see Target IQN number, Click Add to make this as new iSCSI Target. – Now Click on LUN Mapping tab under same option, and allow Write-thru access to Volumes to map LUN.
Is it possible for multiple hosts to share a LUN?
When a LUN is shared by multiple hosts, if a file is used by multiple hosts at the same time, the file may be damaged. Therefore, in order to avoid this situation, multiple hosts must be included in a cluster system to manage the activities of the host.
What is used to connect to an iSCSI target?
iSCSI stands for “Internet Small Computer Systems Interface”. The Microsoft iSCSI Initiator will be used to connect to an iSCSI target from a Windows 7, 8, or other Windows PC. The iSCSI Initiator can connect to an iSCSI target by the Seagate NAS Host Name or by IP Address.
Can multiple iSCSI initiators single target?
The only time to connect multiple initiators to a target LUN is in a failover cluster where only one unit is active using the iSCSI target at a time and the other hosts are inactive. You will screw up something having two or more active hosts on a single iSCSI target as you are now becoming aware.
What is iSCSI multipath?
Multipath I/O is a technique called to increase fault tolerance and performance by establishing multiple paths to the same iSCSI target. In case one of the network connections fails, the iSCSI targets will still be accessible via the other one.
How configure Openfiler iSCSI storage for vmware?

How do I reconnect my target to iSCSI?
To fix this error, go to iSCSI Initiator and delete the reconnecting target from the Favorite Targets tab. After you have done this, follow to the Targets tab, disconnect the reconnecting target manually by pressing the Disconnect button and connect it again.
Do I need iSCSI initiator?
The need for a NIC-based TCP/IP offload engine (TOE) has declined as servers have gained more powerful processing cores. A hardware iSCSI initiator may still be useful for data protection, when booting a server from a local disk, or for security, if the card has built-in encryption capabilities.
How do I use iSCSI targets on Vmware ESXi server with multipath support?
Connect iSCSI Target on the ESXi Server with Multipath Click Configure to configure the settings of the iSCSI Initiator. Make sure the iSCSI Initiator is Enabled. Once the iSCSI Initiator is enabled, click on Dynamic Discovery. Click Add and enter the primary IP Address of the Synology NAS.
How to add an iSCSI port to Openfiler?
Select vmhba33 adapter and click on Properties. – iSCSI Initiator Properties window will appear. Click on Dynamic Discovery tab. – Click Add. – It will ask to provide iSCSI Server IP address. Enter Openfiler IP address here and leave default port as 3260.
How to enable multiple iSCSI sessions for a target?
The MS/T feature creates two or more sessions on the target by varying the initiator’s session ID (ISID). Enabling this feature creates two SCSI layer paths on the network so that multiple targets are exposed through the iSCSI layer to the Solaris I/O layer.
Can a SCSI have more than one host?
SCSI has always been single host and multiple target systems like IDE and SATA. The only time to connect multiple initiators to a target LUN is in a failover cluster where only one unit is active using the iSCSI target at a time and the other hosts are inactive.
Can you connect two hosts to one iSCSI Lun?
You should really study up on iSCSI (I need to study it a bit more too). You should not be connecting two active hosts to one target LUN. iSCSI is an implementation of the SCSI protocol over IP networks. SCSI has always been single host and multiple target systems like IDE and SATA.
