Open-iSCSI Supported Features

3-3

Open-iSCSI is enabled by default on SLES 11 SP2 and login to boot targets is 
triggered by iscsiadm during installation.

The default behavior can be changed by setting the driver parameter 
ql4xdisablesysfsboot to 1, in which case the boot targets in Flash are not 

exported to sysfs, and the driver logs in to the boot targets. The kernel parameter 
withiscsi=1 is not used when ql4xdisablesysfsboot is set to 1.

Prior to RHEL 6.2 and SLES 11 SP2, targets were made persistent by saving the 
entries in Flash. In RHEL 6.2 and SLES 11 SP2, targets managed by Open-iSCSI 
are made persistent by saving them in the user space node and sendtarget 
persistent database. 

For targets in Flash, auto-login is triggered by the QLogic iSCSI driver and 
firmware. For targets saved in the Open-iSCSI persistent database, the iSCSI 
daemon iscsid can be configured to automatically start discovery and login 

through the sendtarget and node persistent databases.

Refer to the following Red Hat Technical Note about issues and 
workarounds when upgrading from RHEL 6.1 to RHEL 6.2: 

 



The additional command line kernel parameter withiscsi=1 must be 

passed before beginning the OS installation. If not, the iSCSI disks will 
not be detected.



The modules qla3xxx and qlcnic should be loaded respectively for 

the 1G and 10G QLogic iSCSI initiator entries to appear in the 
iscsi-client through YaST.

Refer to the following Release Notes for SLES 11 SP2 for the kernel 
parameter withiscsi=1:
