6. Additional Notes
This section provides additional information according to operating system (OS):
6.1 General (Applies to All OSs)
Two different measurement formats are used when displaying the hard drive size: decimal (GB) and
binary (GB). Both Linux and Windows show the correct number using their numeric format:
● Windows uses binary (numbers that are a power of 2).
● Linux uses decimal (numbers that are a power of 10).
For example:
2^10 is 1,024. The closest decimal number is 10^3 or 1,000.
2^20 is 1,048,576. The closest decimal number is 10^6 or 1,000,000.
2^30 is 1,073,741,824. The closest decimal number is 10^9 or 1,000,000,000.
6.2 Windows
Under Windows, the ConfigRequired parameter in the registry dictates how the OS sees devices.
When ConfigRequired=0, both persistently-bound and new devices appear as enabled. This includes
devices that might have been previously unconfigured using SANsurfer FC HBA CLI. You can set this
parameter in the SANsurfer FC HBA CLI Driver Setting, “Present targets that are
persistently bound plus any new target(s) found.”
When ConfigRequired=1, only persistently-bound devices appear as configured. New devices or
devices that were previously unconfigured using SANsurfer FC HBA CLI appear as unconfigured. You
can set this parameter in the SANsurfer FC HBA CLI Driver Setting, “Present
target(s) that are persistently bound only.”
NOTE: For the new Windows driver (version 8.2.0.10 and later), you must set the ConfigRequired
parameter to 1 to prevent the OS from seeing unconfigured entries.
6.3 Solaris
On Solaris, the qla_mp_config_required parameter in the configuration file dictates how the OS sees
devices. The qla_mp_config_required flag in the QLogic configuration file (qla2x00.conf) controls
persistent binding of targets. The default configuration file that comes with the QLogic driver does not
have an entry for this flag. An entry for this flag appears in the configuration file only after saving the
target configuration data with SANsurfer FC HBA CLI.
By default, SANsurfer FC HBA CLI sets the qla_mp_config_required flag to 1. When this flag is set to
1, the driver reports only target devices that are persistently bound in the configuration file to
the OS. The driver does not report any new or unconfigured targets to the OS. In other words, the
default behavior for this flag is “Persistent Targets Only.”
When the qla_mp_config_required flag is set to 0, the driver reports both persistently bound and new
targets to the OS. This is equivalent to “Persistent Plus New.”
NOTEs:
● SANsurfer FC HBA CLI does not read the value of the persistent-binding-configuration
parameter from the configuration file.
● The QLC driver does not support persistent binding or failover configuration.
