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 Windowsclustered 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.
- 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 in these situations.
