NAME¶
isnsdd - iSNS discovery daemon
SYNOPSIS¶
isnsdd [
-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 processes
these. It can be configured to invoke an external helper application 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
specifying 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 register
itself with the iSNS server. Role can be either initiator,
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
