Configuring persistent binding for the Linux QLogic iSCSI HBA
This section provides the instructions for enabling persistent binding for the Linux QLogic iSCSI HBA v3.x- or
Note: Future revisions of this driver will not contain the target level binding mechanism that is now present, and the Linux kernel udev() functionality will be used as a per device persistent binding mechanism. This mechanism may be used in lieu of the driver's target level persistent binding mechanism with this driver.
In an iSCSI LAN environment, EMC recommends, but does not require, enabling persistent binding in the driver.
Without a persistent binding mechanism, the host will be unable to maintain a persistent logical routing of communication from a storage devices object across the fabric to an EMC storage array volume. If the physical configuration of the switch is changed (for example, cables are swapped or the host is rebooted), the logical route becomes inconsistent, which could cause possible data corruption.
Note: Please note that the persistent binding mechanism in the QLogic driver is
