SYNOPSISisnsdd [-f] [-c filename] [-d debug-facility]
DESCRIPTION
Isnsdd is a client side daemon for iSNS. It registers storage nodes and
portals with the iSNS service, and refreshes these registrations in a
timely manner.
The daemon also registers itself to receive SCN notifications, and pro‐
cesses these. It can be configured to invoke an external helper appli‐
cation for each status notification received. The path name of the
helper application can be specified via the SCNCallout option in the
configuration file.
OPTIONS
By default, isnsd will take most of its settings from the configuration
file /etc/isns/isnsdd.conf, with the addition of the following command
line options:
--config filename, -c filename
This option overrides the default configuration file.
--foreground,-f
By default, isnsd will put itself into the background. By speci‐
fying this option, you can tell it to run in the foreground. Any
error messages or debug output will be printed to the console
rather than being sent to syslog.
--role role
This tells the discovery daemon in which capacity is should reg‐
ister itself with the iSNS server. Role can be either initia‐
tor, or control. The default is to register as an initiator.
Registering target nodes needs to use a different mechanism, as
the iSCSI target server needs to inform the discovery daemon
about each exported target separately. This is not implemented
yet.
--debug facility, -d facility
enables debugging. Valid facilities are
┌────────┬─────────────────────────────────────────────────────┐
│socket │ network send/receive │
│auth │ authentication and security related information │
│message │ iSNS protocol layer │
│state │ database state │
│scn │ SCN (state change notification) messages │
│esi │ ESI (entity status inquiry) messages │
│all │ all of the above │
└────────┴─────────────────────────────────────────────────────┘
