chrisgreenwood Posted August 9, 2023 Posted August 9, 2023 Hi, Been setting up our VMs to autostart on the hosts (and even the hosts them selves) but been thinking about the actual server itself. i read it should auto turn it self on after a powercut but if i was to gracefully shut it down in a powercut, whats the best procedure for turning everything back on or will it do it self?
FN-GM Posted August 9, 2023 Posted August 9, 2023 Usually there are 2 bios options 1. Always Power On 2. Use the last power state. 1. Will always turn on the server when the poet cycles. 2 will only power it on if it was running when the power was lost. If it was gracefully shutdown it will stay off. 1
DavR Posted August 10, 2023 Posted August 10, 2023 We used to have one of those (well, still do, because I'm loathe to scrap that much storage). IIRC, I had the blade servers themselves set to shut down gracefully after UPS power expires, then start again when power is restored. VMs shutdown / start up with the servers. I may have put a 180s delay in there, to guard against intermittent power faults, but I'm not sure now. The chassis itself didn't have any useful power control options that didn't involve scripting, so I just left that on ungraceful shutdown when power runs out, and automatic start when power returned. 1

How did you get them to gracefully shutdown?
DavR Posted August 10, 2023 Posted August 10, 2023 How did you get them to gracefully shutdown? We had a network connected UPS, and ran the APC network appliance as a VM, which shut down VMs and blade servers when power runtime started running out. It's a bit fiddly to set up, but it was the only way for us to shut down multiple blade servers with a single UPS.
