Allow the ssh connection to automatically wake a remote machine, with the appropriate parameters, to establish a connection to the disks.
When the "Wake on ethernet network administrator access" option in the system prefs is selected, a remote Mac can be awakened by a specially formed "magic packet". This packet can be generated (for example) by the following script:

import time, struct, socket, commands
def WakeOnLan(ethernet_address, hostname):
ipaddr=commands.getoutput('host %s' % hostname).split()[-1]
print ipaddr
# Construct a six-byte hardware address
addr_byte = ethernet_address.split(':')
hw_addr = struct.pack('BBBBBB', int(addr_byte[0], 16),
int(addr_byte[1], 16),
int(addr_byte[2], 16),
int(addr_byte[3], 16),
int(addr_byte[4], 16),
int(addr_byte[5], 16))
# Build the Wake-On-LAN "Magic Packet"...
msg = '\xff' * 6 + hw_addr * 16
# ...and send it to the broadcast address using UDP
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
s.sendto(msg, (ipaddr, 9))
s.close()
# Example use
#time.sleep(60)
WakeOnLan('FF:FF:FF:FF:FF:FF','me.site.org')
The user would have to supply the MAC address of the machine to be able to do this trick. The IP address should be determined via DNS lookup.
