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.


Install ESXCLI. See Getting Started with ESXCLI. For troubleshooting, run esxcli commands in the ESXi Shell.


  • To add or duplicate an iSCSI session, run the following command:
    esxcli iscsi session add
    The command takes these options:
    Option Description
    -A|--adapter=str The iSCSI adapter name, for example, vmhba34. This option is required.
    -s|--isid=str The ISID of a session to duplicate. You can find it by listing all sessions.
    -n|--name=str The iSCSI target name, for example, iqn.X.

What to do next

Rescan the iSCSI adapter.
