Fatigue toward the end of a prolonged sporting event may result as much from dehydration as from fuel substrate depletion. Exercise performance is impaired when an individual is dehydrated by as little as 2% of body weight.
When host IPMI system event log status alarm is triggered repeatedly in the Hardware Status tab in vCenter Server 4.x, 5.x or 6.x, clear the IPMI System Event log file located at /var/log/ipmi. This issue occurs when the IPMI System Event log file is full, which triggers the alarm that monitors the log file.
When you plug a USB device in, the host becomes aware (because of the pullup resistor on one data line), that a device has been plugged in. The host now signals a USB Reset to the device, in order that it should start in a known state at the end of the reset. In this state the device responds to the default address 0. Until the device has been reset the host prevents data from being sent downstream from the port. It will only reset one device at a time, so there is no danger of two devices responding to address 0.
