NAME

6       isnsdd - iSNS discovery daemon
7

SYNOPSIS

9       isnsdd [-f] [-c filename] [-d debug-facility]
10
11

DESCRIPTION

13       Isnsdd is a client side daemon for iSNS. It registers storage nodes and
14       portals with the iSNS service, and refreshes these registrations  in  a
15       timely manner.
16
17       The daemon also registers itself to receive SCN notifications, and pro‐
18       cesses these. It can be configured to invoke an external helper  appli‐
19       cation  for  each  status  notification  received. The path name of the
20       helper application can be specified via the SCNCallout  option  in  the
21       configuration file.
22

OPTIONS

24       By default, isnsd will take most of its settings from the configuration
25       file /etc/isns/isnsdd.conf, with the addition of the following  command
26       line options:
27
28       --config filename, -c filename
29              This option overrides the default configuration file.
30
31       --foreground,-f
32              By default, isnsd will put itself into the background. By speci‐
33              fying this option, you can tell it to run in the foreground. Any
34              error  messages  or  debug output will be printed to the console
35              rather than being sent to syslog.
36
37       --role role
38              This tells the discovery daemon in which capacity is should reg‐
39              ister  itself  with the iSNS server.  Role can be either initia‐
40              tor, or control.  The default is to register as an initiator.
41
42              Registering target nodes needs to use a different mechanism,  as
43              the  iSCSI  target  server  needs to inform the discovery daemon
44              about each exported target separately. This is  not  implemented
45              yet.
46
47       --debug facility, -d facility
48              enables debugging. Valid facilities are
