command.
Before running the saconfig command to configure the storage devices connected to a RAID160 SA
controller, you will need to know the device file for the RAID160 SA controller.
Determining the RAID160 SA Device File
The device file for the RAID160 SA controller can be determined from the output of the ioscan -kfn
command. An example of a portion of the ioscan -kfn output listing the RAID160 SA device file follows:
# ioscan -kfn
