Procedure
Use the following procedure to scan the devices and make them available to multipathing without
rebooting the system.
1 On the storage subsystem, use the vendor's tools to allocate the device and update its access
control settings to allow the Linux system access to the new storage. Refer to the vendor's
documentation for details.
2 Scan all targets for a host to make its new device known to the middle layer of the Linux
kernel's SCSI subsystem. At a terminal console prompt, enter
