v2 v3 18 18 particular round of repairs. 19 19 20 4) Comment out lines for these nodes from dhcp1:/etc/dhcp3/dhcpd.conf. 21 Restart dhcpd on dhcp1. 22 23 5) For each node to be repaired, remove each node from its mounting in 20 4) For each node to be repaired, remove each node from its mounting in 24 21 the grid, leaving the node id box attached. As you remove nodes, take 25 22 them and their node id box back to the node repair area. One or two … … 28 25 hardware or incorrectly installed connections on the wiki page. 29 26 30 6) Once in the node repair area, remove the node id box and then the 27 ) Once in the node repair area, remove the node id box and then the 31 28 yellow node enclosure. Verify that the node id boxes match the list 32 29 of nodes to be repaired on the wiki page, and that the 802.11 hardware 33 30 vendor matches what is expected. Note exceptions on the wiki page. 34 31 35 7) Replace the power supply. Take care to put old power supplies in 32 6) Replace the power supply. When attaching the new power supply to 33 the chassis, put in all four screws loosely first, then tighten once 34 all four are in place. Take care to put old power supplies in 36 35 the garbage bin. If the 802.11 hardware vendor did not match what is 37 36 expected, correct the hardware. Replace the enclosure. Replace the 38 node id box. 37 node id box. Do not replace the side enclosure screw, we no longer 38 use them. 39 39 40 8) Calibrate the node (NYI). 40 7) Bring the node to the calibration shelf. Attach the CM cable, 41 CONTROL cable, power cable, and two antennas. Run the calibration 42 experiment. 41 43 42 8) Replace the node in the grid. Verify the node id box against two 43 adjacent nodes. 44 8) Replace the node in the grid. 45 adjacent nodes. 44 46 45 47 9) Once all nodes have been repaired and replaced, verify that the 46 48 nodes are not red on the orbit-lab.org/wiki/Staus page. That is, that 47 the CM reports back to the CMC correctly. 49 the CM reports back to the CMC correctly. Note exceptions in the wiki 50 page. 48 51 49 10) Turn the repaired nodes on. Because they obtain pool addresses 50 from dhcp, they will load an 'inventory' image (NYI). Wait five 52 10) Comment out lines for these nodes from dhcp1:/etc/dhcp3/dhcpd.conf. 53 Restart dhcpd on dhcp1. 54 55 11) Turn the repaired nodes on. Because they obtain pool addresses 56 from dhcp, they will load an 'inventory' image. Wait five 51 57 minutes for the inventory image to finish loading, and for the inventory 52 58 script to run. 53 59 54 1 1) Run the gendhcpconf script on repository2. Compare its output 60 1) Run the gendhcpconf script on repository2. Compare its output 55 61 with the entries you commented out in step 4. Correct 56 62 dhcp1:/etc/dhcp3/dhcpd.conf if needed. 57 63 58 12) During the following maintenance slot, verify that you can image 59 all nodes that have been repaired since the last maintenance slot by 60 running the CM stress experiment (NYI). 64 13) If there is time, verify that imaging works on the repaired nodes.
