"W" means "don't know When this task will be done"
Soon: /etc/motd on pcluster, zcluster
========================================================================
Wednesday:
Morning: GD message to users
2 PM: CC VM snapshots
3 PM:
PB disable logins pcluster
PB disable logins zcluster (except for jkissing, students)
PB kick users off pcluster
PB kick users off zcluster?
PB drain all nodes or queues, pcluster
PB disable all queues except somedevq, zcluster
PB kill all jobs pcluster
PB kill all jobs zcluster
JS move some rack15 nodes to rack 16?
do GE jobs testing MPI and storage I/O throughput
CC to use fsr15 for iozone
ST to use fsr12 for MPI/NAMD
PB to use fsr7 for dumb I/O
PB stop execd on all nodes, zcluster
shut down racks 8,9,10,11
4 PM:
CC reconfigs NICs/LAGs on storage units
PB modify PanFS blksize on remaining nodes
CC shut down VMs (wait for Jessie off zcluster)
shut down 3070s (umount first)
PB shut down Panasas (umount first)
CC connect ESX IPMI cat5
by 5PM:
we tell NEG "go ahead"
CC recable storage unit cat5, and work with Brian M on switch port configs
probably between 9 and 12PM, NEG finishes
================================================================================ "Midnight" (when NEG is done): power up 3070s power up Panasas CC power up ESX servers and VMs PB start final rsyncs power up racks 8,9,10,11 "Morning" (starting by 8AM)======================================================= PB panasas OS upgrade PB switch and test /db, /usr/local mounts on the zcluster PB/ST, CC do GE jobs testing MPI and storage I/O throughput PB enable Panasas jumbo frames and reboot Panasas VMWare updates W: PB GE upgrade W: PB yum updates of nodes W: PB yum update of zhead W: PB update FW on Dells W: CC thumper upgrades W: CC rccstor upgrades W: PB reinstall rack11, if time W: PB upgrade PGI compiler PB switch and test NFS mounts on pcluster PB reenable queues on zcluster PB resume queues on pcluster enable logins pcluster enable logins zcluster email users that outage is over contact Lab Storage users about their mounts
