sfd[2330]: execution of 'insf' completed.
Always use the -N option for the ioscan command to see the persistent devices or agile
devices. Without the -N option, legacy devices will be seen.
NOTE: Broken or stale device paths are displayed with S/W state of NO_HW in the output
of the ioscan -kfnNC disk command. The CLAIMED state indicates a valid disk device
path existence.
Example: Without the -N option, legacy devices are shown.
# ioscan -kfnC disk
