Shutdown priorities

The following list puts priorities on computers, equipment and other items of interest. Computers in racks, which will stay powered up, should be unplugged!

Shutdown plan

level	what / detailed ordered list
1	no standard computation, quick to recover
1.1	ra01..ra10
1.2	n0422..n0588 (Lenny)
1.3	n0589..n0840
1.4	n1345..n1662
1.5	E@H mirror
2	harder to recover
2.1	obsolete Racks, obsolete LCPs, Umluftkühler
2.2	gpudev{1,2,3,4}, gpu0{1,4,5,8}, PS3
2.3	mds2, s00, FAI-lenny, monitor-nodes
2.4	E@H dev machines (PowerMac, MacPro, ...)
3	basic cluster service down
3.1	bob, scr01, einstein-dl2, QFS-clients, DDN
3.2	cfengine, kerberos, unknown(mgmt/25), epilog, cornell, p-kvm, condorslave, external01
3.3	einstein-home, d3{3,4,6,7,8,9}
3.4	file server (possible except d03 for now)
4	limited access to cluster
4.1	postfix, titan1, titan2, titan3, atlas3, atlas4
4.2	switch off condor on atlas1, then condormaster, backup server
4.3	vm, n0, LDR, geosegdb
4.4	switch off 8 of condordev's pool
5	no user access possible
5.1	thumper (not s12), MDS server, 6780, atlas2, fluffier, bute
6	going unsafe
6.1	nut
6.2	by-pass UPS
7	second to last barrier
7.1	condor dev pool, condordev, s12, orion
7.2	einstein-wug, einstein-db
7.3	einstein-abp1, einstein-dl
7.4	atlas1, fai
8	no network, no monitoring, no access, no nothin'
8.1	darkness (switching...)

Core/External network

• Cisco switch
• Woven/Fortinet switches
• HP mgmt switch

Head node/condor - most important ones

• atlas1 (web server for LVC meeting)
• condormaster?
• monitoring server/nodes
• n0
• VM
• LDR
• FAI

einstein related - important

I think these are all needed

• einstein-wug
• einstein-abp1
• einstein-dl
• condordev
• orion
• very few condordev nodes
• s12

einstein related - not that important

These might not be needed right now (ask Bernd/Olli)

• einstein-db
• einstein-dl2

$HOME servers

• s02..s11/s13
• HSM
• MDS/MDS2
• QFS clients

headnodes/othe rmachines - not so important

• atlas2/3/4 (atlas4 should be more available than atlas2)
• atlas2 is NAT gateway, but needed?
• titan1/2/3

misc (mgmt) nodes

• nut
• bob
• gpudev
• gpu
• eahm
• scr01
• Macs/Playstation
• file server (d01.."d40")

most dispensable

• compute nodes
• s00
• gpuXXX *

MISC

• Any Rittal racks should be shut down which are not needed
• Air conditioning
• UPS?
