NAT

10.0.0.1 # cisco firewall, default gateway

defines the 10.0.x.x private network for GT. The WAN name for this NAT is gt1.phy.anl.gov. Note: this NATBOX is not the standard GT ASA box; but the NAT box we use many places at ANL.

Decomposition computers

10.0.1.100              n0000 n0000.gam
10.0.1.1                n0001 n0001.gam
.
.
10.0.1.62               n0062 n0062.gam

n0000 is the Global Event Builder (GEB). The other ~60 nodes are decomposition computers. A few of them are dead.

service/analysis computers

10.0.0.5	dell-6248-master # Dell swith, master, middle rack
10.0.0.7	dell-6248-shack # Dell swith, up on the shack

10.0.0.79	a0.gam a0 a0.gam.nscl.msu.edu
10.0.0.98	a1.gam.nscl.msu.edu a1.gam
10.0.0.99	a2.gam a2 a2.gam.nscl.msu.edu

The role of a1.gam is that of the NIS server, but like a2.gam it is also used for general software developments. At the moment we run all the DAQ control screens (and soft IOCs) from a1.gam

10.0.0.10	dogs.gam dogs dogs.gam.nscl.msu.edu

the decomposition machines get their systems from dogs (true?)

10.0.0.50	fs.gam fs fs.gam.nscl.msu.edu
10.0.0.51	fs2.gam fs2 fs2.gam.nscl.msu.edu
10.0.0.52	fs1.gam fs1 fs1.gam.nscl.msu.edu

the root host machine for fs1.gam is a1 (we think)

10.0.0.70	spdaq44 spdaq44.gam

10.0.0.110	sol.gam sol.gam.nscl.msu.edu sol

sol is the boothost for all the Digiticer IOCs

The computers above get their password file via NIS from a1.gam. Not all computers exists

Digiticer IOCs

10.0.3.1		vme01
10.0.3.2		vme02
.

10.0.3.47		vme47

User and access computers

10.0.10.11     reserved for tl laptop
10.0.10.12     ws1.gam ws1
10.0.10.13     ws2.gam ws2
10.0.10.14     ws3 gam ws3

these computers have their own password files independent of the NIS server a1.gam. In particular, access to ws1 is restricted to personel that need outside access to the GRETINA network at anl. (ws1), ws2 and ws3 are general purpose linux workstations for users to use and sort data on during experiments.

LN fill computers

10.0.4.11		gln1
10.0.4.12		gln2

misc other computers we know of

10.0.4.1       caenps01
10.0.4.2       caenps02
10.0.8.11	jays-happy-place
10.0.8.12	daqtape
10.0.9.11	middlemac

computer shutdown procedure

(for computers in g126 computer room)

- log in to ws1
  umount anything from fs1.gam (or you will have
  problems shutting down ws1)
- a2.gam  (shutdown -h now)
- sol.gam (shutdown -g0 now) turn power off by hand
- ssh [email protected]
    pdsh -w n00[00-61] shutdown -h now
    shutdown dogs.gam (shutdown -h now)
- ssh [email protected]
    lsof | grep global <--- kill processes
    pkill -u gretina
    pkill CArepeater
    umount anything from fs1.gam
    then shutdown fileserver fs1.gam as
       ssh fs1.gam, then issue command 'halt -t 1'
       rsh fs1.gam halt -t 1 <-- not correct
- Turn off the file server shelves
- Turn off the file server head
- a1.gam (shutdown -h now)
- 2 switches in racks sw02  & sw03
- ws1 (shutdown -h now)
- power off gt1.phy.anl.gov NAT box
- throw 5 three phase switches in control panel

computer powerup procedure

- switches - sw02 and sw03
- fileserver - fs1.gam
   - Turn on fs1.gam head
   - Turn on the shelves
- NIS master - a1.gam
- a2.gam
- sol.gam
- dogs cluster
   - Power on dogs.gam
   - 'sh /root/ipmi/ipmi.poweron' to use IPMI to power on all compute nodes
- 30 VMEs
- op3.gam
- op4.gam
- op5.gam
