<> == People == * BtTempleton * SrikanthSastry * ClintonEbadi == Goals == * Install new disks that actually work into fritz * Determine whether Belkin KVM and IPKVM are dead or alive * Remove dead [[KrunkInfoz|dead server]] and hard drives from rack * Clean up cables in rack as best as possible * Set up management LAN == Report == * New disks installed and set up * Disks were removed from krunk, and, after a short wake, krunk was placed onto the recycling pile * The Belkin KVM is alive. The IPKVM's status is still unknown. * The switch ordered at the last minute for the management LAN was not useful. Will be RMA'd and replaced. Thus, the management LAN does not yet exist. * SrikanthSastry is now familiar with the inner workings of the datacenter facilities and our cabinet, and spearheaded a multi-hour effort to eliminate the rat's nest of cables * Detritus, and its fate: * An ethernet cable and two power cables were found that went nowhere, and were recycled. * We managed to get everything plugged into the colo provided power strip, and similarly threw our old ratshack power strip into the recycling pile * We decided that we really did not need the drive blanks for fritz and dropped them on the spare-hardware/recycle-if-no-one-wants-it table * The two 500G disks that did not work in fritz were labelled "Good" and placed into a similarly labeled box left in the rack. We can put them into our next machine since they are past the return period. === Status of the Cabinet === (These pictures have been resized somewhat, and are from ClintonEbadi's mediocre phone camera. A bit more detail is available if you view the image directly). Front/Back of cabinet before we removed detritus and made a first pass at clearing cables: {{attachment:front-of-rack-20130626.jpg|Front of Cabinet, before|width=512}} {{attachment:back-of-rack-20130626.jpg|Back of Cabinet, before|width=512}} Front/Back of cabinet after we removed detritus and tried to clear the cable nest: {{attachment:front-of-rack-20130627.jpg|Front of Cabinet, after|width=512}} {{attachment:back-of-rack-20130627.jpg|Back of Cabinet, after|width=512}} Although the back of the rack might not look much better from this picture, it is actually significantly more accessible. A number of power and Ethernet cables were completely entangled and now every cable has a clear route. The main problem now is that all of our cables are 6+ feet long in a two foot tall space... And a funeral for [[Krunk|KrunkInfoz]] before being thrown onto the recycling pyre: {{attachment:krunk-drives-removed.jpg|Drives removed from krunk|width=512}} {{attachment:clinton-says-goodbye-to-krunk.jpg|Clinton hugs krunk goodbye|width=512}} == Plans == * Order a new positive-polarity 12V/1.5A power supply and see if the IPKVM is still alive * We might just want to give up and de-rack the Belkin KVM to get an extra 1U of space and also eliminate the bulky VGA/PS2 cables. Seems viable, especially since most of our machines are usb-only, and the usb to ps/2 adapters we have are occasionally flaky, defeating the purpose of having a remote console. * Acquire another switch for an IPMI management LAN * If we do this, then deleuze and fritz can be controlled, securely, from hopper. We would have power management and a remote serial console (after some BIOS/grub/getty hacking on-site). Any new machines we will get will also support IPMI, so this seems like the way forward for remote control. * Alternative: Acquire a 16+ port managed gigabit switch that can segregate ports into separate "physical" LANs or at least VLANs. Depends on opportunity cost. * All of our ethernet cables are way too long. Replace with shorter ones, ideally ones that we cut to length. * We should replace the power cables, since they are also all way too long (6-10' each!) * We might want to acquire a rack mounted PDU to supplement the colo-provided strip. Not a huge deal (yet), since we have to remove at least one server to put anything new in.
