DISKLESS -- Diskless node support information -- 83/09/24
When a diskless node is first powered up, it sends a message through
the network asking for any node with a disk (a "disked" node) to act as
a diskless node boot partner. The diskless node will not normally run
unless a willing partner volunteers.
Configuring a disked node as the boot partner for one or more diskless
nodes is a 2-step process.
1. While seated at the disked node, EDIT the file
/SYS/NET/DISKLESS_LIST, and add to this list the network
node IDs of the nodes for whom this disked node should
volunteer booting aid. An example of a usable diskless_list
file can be found in /SYS/NET/SAMPLE_DISKLESS_LIST.
2. Make sure that the diskless node boot server process NETMAN is
running on the disked node by typing $ PST and looking for a
process named "netman." (This process is normally started
from the startup command file /SYS/NODE_DATA/STARTUP,
which is executed when a disked node is powered up. EDIT this
file and be sure that the line
cps /sys/net/netman
is not commented out with a "#.") If the NETMAN process is not
running on your node, press <CMD> and type
Command: CPS /SYS/NET/NETMAN
Once the node ID of a diskless node is entered into the diskless list of
a node that is running NETMAN, powering up the diskless node should be
the same as powering up a disked node.
