[edit] ATLAS Cluster and related ATLAS Machines

So far, the cluster master is already 64-bit SL5, atlaspc02 is already 32-bit SL5, and the non-cluster machines atlasremote and atlas-tier3-c6 are 64-bit and 32-bit SL5 respectively. We also have the SL5 VMs atlas-sl5x32 and atlas-sl5x64.

[edit] SL5, 32-bit:

atlaspc02 (64-bit arch, full ganglia, nagios ping)
atlas-sl5x32 (VM)
atlas-tier3-c6 (not in cluster anymore, 32-bit arch, local install machine for ALRB)
atlascas1 (formerly atlas-tier3-c7, not in cluster anymore, runs AtCan services)

[edit] SL5, 64-bit:

atlascm (cluster master)
isabel1 (full ganglia, nagios ping)
atlaspc01 (turns out to be 64-bit arch, full ganglia, nagios ping)
atlasremote (not in cluster, used as local install machine for ALRB)
atlas-sl5x64 (VM)

[edit] SL4, 32-bit:

isabel (32-bit arch, full ganglia, nagios ping)
lin29 (64-bit arch)
atlaspc03 (arch?, full ganglia, nagios ping)
atlas-tier3-c1 (32-bit arch, full ganglia, nagios services)
atlas-tier3-c2 (32-bit arch, full ganglia, nagios services)
atlas-tier3-c3 (32-bit arch, full ganglia, nagios services)
atlas-tier3-c4 (32-bit arch, full ganglia, nagios services)
atlas-tier3-c5 (32-bit arch, full ganglia, nagios services)
atlas-tier3 (not in cluster, 32-bit arch, full ganglia, nagios monitors up/down, full nagios services on AtCan  nagios, local install machine for ALRB)
atlas-tier3-b (not in cluster, 32-bit arch, full ganglia, nagios monitors up/down, full nagios services on AtCan nagios)

[edit] SL4, 64-bit:

atlas-tier3-ds01 (full ganglia, nagios services, local install machine for ALRB)
arthurpc (full ganglia, nagios ping)
atlas-tier3-ds02 (no ganglia, nagios thinks it's down - no nrpe)
atlas-tier3-c8 (no ganglia, nagios thinks it's down - no nrpe)
atlas-tier3-c9 (no ganglia, nagios thinks it's down - no nrpe) 

[edit] not sure / need to check

atlascas0 (VM, formerly atlas-canada.triumf.ca, not in cluster, runs AtCan services)
gort (SL5)
klaatu (SL4, VM)
