iSCSI Sessions 8.1.2 Individual Device Info By clicking on the blue triangle in the Device info box you can display further information about each SAS device. The expanded information also gives you two further options. Persistent LUN - if you select this option, the device will always be presented to the iSCSI interface in exactly the same way - i.e. the same IQN. If the device is disabled or has been removed from the SAS port the IQN will be reserved and will not be assigned to any other SAS device. Enabled - This pull down menu option allows you to disable a SAS device from appearing on the iSCSI interface. This is useful if you wish to reserve a device or to take it out of commission for repair or replacement at a later date without powering down the bridge. IQN - iSCSI Qualified Name iSCSI naming convention that uniquely identifies every device. An IQN is up to 255 characters long. LUN - Logical Unit Number - A LUN is a number which identifies a sub-element within a SCSI target device. This is normally used to refer to the device itself.
