The iswd daemon is involved in the connection management for the
iSCSI Software Interface Driver. It opens and terminates TCP connections
interfacing with the iSCSI Software Interface Driver.

 | CAUTION: The iswd deamon is required to access the iSCSI devices. To avoid
upredictable results, the deamon must not be terminated. |

If a target device cannot be seen from the HP-UX host, verify
that the iswd daemon is alive by executing
If the iswd daemon is not alive, restart the daemon and re-issue
an ioscan by executing
# /usr/sbin/ioscan -H 255
If the iswd daemon is accidentally terminated the behavior displayed
depends on the state of the iswd daemon. The most likely scenario
would be:
An attempt to
terminate (kill) the iswd daemon will have no effect initially as
the daemon thread is sleeping in the kernel waiting for connection
open requests. The active outstanding connections will not be affected
as long as the daemon thread is in kernel space.
The signal sent by the kill(1)
command is queued and serviced once the daemon thread goes to user
space upon an enqueue of a connection open request, causing the
iswd daemon to be terminated. A Connection open request is enqueued
when a command requiring iSCSI target access is executed.
The less likely scenario would be
An attempt to
terminate (kill) the iswd daemon when the thread is in user space
will cause the daemon to be terminated immediately.
ACTION: Restart the iswd daemon in both the above scenerios
The following message will be displayed during execution of
shutdown(1m) or reboot(1m).
reboot: CAUTION: some process(es)
wouldn’t die
This message is the result of the iswd daemon being kept alive
to complete various tasks during reboot. When iSCSI is configured
in a system, this message may be ignored.
