Target Scan - Hitachi GVX-CC64GxBX series User Manual

Target Scan

[Function] If you execute on this command in the system configuration which FC-SAN disk is
connected through FC-Switch, the driver initiates to scan process of the target then it can detect
new target.
When Windows has already identified the target and only LUs are added or removed, the driver
does not detect added or removed LUs when executing this command. In such case, execute
rescan operation, which OS is provided. (For example, a disk scan is performed from the device
manager of Windows.)
In the following cases, the new target is detected by the driver without executing this command.
 When RSCN is reported to the adapter, such as 1) cables is plugged or
unplugged between the adapter port to FC-Switch, or FC-Switch to the FC-SAN
disk, or 2) zoning is changed in FC-Switch.
 The FC-SAN disk has a feature to send RSCN to the adapter when changing
LUN security.
