sfd[2330]: started 'insf' to create device special files for newly found devices.

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.

HP recommends that you do not use the legacy device paths; instead, migrate any application
from legacy to persistent device paths by disabling the legacy device paths. All LVM commands
