Installing and Configuring the QLogic HBA and v8.x-Series Driver

QLogic v8.x-series driver parameters

The QLogic driver contains a number of parameters that may be

modified to perform failover functionality or to enhance

performance. The QLogic and EMC recommended values are

inTable 3 and descriptions of the parameters follow the table.

The values to which these parameters are set are dependent upon the

environment and the type of applications and subsequent I/O being

used on the system. Currently, the values in the EMC Default

Recommendations column apply to both PowerPath and non-HA

connections. Please keep in mind that these are merely guidelines as

each environment differs.

Note: EMC does not support the failover functionality within the QLogic

driver. As a result, the parameters related to the failover functionality are not

used by EMC.

The changes to the parameters will not take effect until the driver is

reloaded or the host is rebooted.

Note: Note the following: 0 = disabled; 1 = enabled
