HP-UX I/O Subsystem EVM Events

5.1 I/O Node State Change Event
An I/O node is said to change its state when the software state of the node changes. An I/O node can
assume the following software states:
CLAIMED The I/O node is bound to a driver.
UNCLAIMED The I/O node is not bound to any driver.
UNUSABLE The hardware at this address has become unusable as a result of some error
condition.
SUSPENDED The associated hardware and software are in a suspended state.
NO_HW The hardware at this address is no longer responding to scan requests.
ERROR The hardware at this address is in an error state.
REMOVED The hardware at this address has been removed.
An EVM event is generated when the state of the I/O node is changed to one of the above mentioned
states.
Given below is the format in which the I/O node state change event is generated:
Event Full name:
sys.unix.io.state_change.new_state._class.ccc._instance.
iii._cim.HP_EVMEventIndication

Example: Suspend the driver associated with the card using the command “olrad –r <slot_id>”. This
command prepares a slot for replacement. The associated driver of the card is suspended. For more
information on the olrad command, see the olrad(1M) manpage.
# olrad –r 3
