Use the vCLI to add an iSCSI session for a target you specify or to duplicate an existing session. By duplicating sessions, you increase the default number of sessions and create additional paths to storage systems.

About this task

In the procedure, --server=server_name specifies the target server. The specified target server prompts you for a user name and password. Other connection options, such as a configuration file or session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces.


Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.


To add or duplicate an iSCSI session, run the following command:

esxcli --server=server_name iscsi session add

The command takes these options:




The iSCSI adapter name, for example, vmhba34. This option is required.


The ISID of a session to duplicate. You can find it by listing all sessions.


The iSCSI target name, for example, iqn.X.

What to do next

Rescan the iSCSI adapter.
