=head1 NAME

B<getmacs> - Collects node MAC address.

=head1 SYNOPSIS

I<getmacs [-h| --help]>

I<getmacs [-v| --version]>

I<getmacs [-V| --verbose] noderange> [-f][-d][-D -S server -G gateway -C client]


=head1 DESCRIPTION

The getmacs command collects MAC address from a single or range of nodes.
Note that on AIX systems, the returned MAC address is not colon-seperated (for example 8ee2245cf004), while on Linux systems the MAC address is colon-seperated (for example 8e:e2:24:5c:f0:04).
If no ping test performed,  getmacs writes the first adapter MAC to the xCAT database.  If ping test performed, getmacs will write the first successfully pinged MAC to xCAT database.

=head1 OPTIONS

B<-C>          Specify the IP address of the partition for ping test. The default is to read from xCAT database if no -C specified. 

B<-d>          Display MAC only. The default is to write the first valid adapter MAC to the xCAT database.

B<-D>          Perform ping test.

B<-f>          Force immediate shutdown of the partition.

B<-G>          Gateway IP address of the partition.  The default is to read from xCAT database if no -G specified.

B<-h>          Display usage message.

B<-S>          The IP address of the machine to ping.  The default is to read from xCAT databse if no -S specified.

B<-v>          Command Version.

B<-V>          Verbose output.


=head1 RETURN VALUE

  0 The command completed successfully.

  1 An error has occurred.


=head1 EXAMPLES

1. To retrieve the MAC address for the HMC-managed partition lpar4 and write the first valid adapter MAC to the xCAT database, enter:

I<getmacs lpar4>

Output is similar to:

lpar4:

#Type  Location Code   MAC Address      Full Path Name  Ping Result

ent U9133.55A.10B7D1G-V12-C4-T1 8e:e2:24:5c:f0:04 /vdevice/l-lan@30000004  virtual



2. To retrieve the MAC address for the HMC-managed partition lpar4 and display the result only, enter:

I<getmacs lpar4 -d>

Output is similar to:

lpar4:

#Type  Location Code   MAC Address      Full Path Name  Ping Result

ent U9133.55A.10B7D1G-V12-C4-T1 8ee2245cf004 /vdevice/l-lan@30000004 virtual



3. To retrieve the MAC address while performing a ping test for the HMC-managed partition lpar4 and display the result only, enter:

I<getmacs lpar4 -d -D -S 9.3.6.49 -G 9.3.6.1 -C 9.3.6.234>

#Type  Location Code   MAC Address      Full Path Name  Ping Result

ent U9133.55A.10B7D1G-V12-C4-T1 8e:e2:24:5c:f0:04 /vdevice/l-lan@30000004 successful virtual
