About multisession configuration

Edit online

Several characteristics must be considered when you configure an iSCSI multisession.

The following points apply to multisession configuration:

  • The AIX® iSCSI initiator does not support multisession.
  • The use of the supported iSCSI multipathing is recommended when running the I/O with multisession.
  • If you use CHAP authentication under the Microsoft Windows operating system, use the same secret across each session that is initiated from that host to a particular target.
  • If the Microsoft Windows clustered system is rebuilt or restored from a backup, hosts must log off and then log back on to any previously connected iSCSI targets that are supplied from the system.
  • If the host application uses SCSI 3 Persistent Reservation, you must run only a single iSCSI session per node.
  • Running with multiple iSCSI sessions is not supported for applications that use Microsoft 2008 Failover clustering over an iSCSI interface. You must run only a single session per node in these situations.
