Re: [Nut-upsuser] problem with nut APC BackUPS RS 1500 (white)

2018-03-28 Thread p1_p1_p1
i have tested maxretry + retrydelay with ups in usb 2.0 port with same 
result - driver cant start automaticaly, after two manual starts is nut 
running, so no difference if i specify maxretry 10 retrydelay 20 or 30 or 60 
and same results -

driver wont start automaticaly

so i moved with this ups today to test it on 3 another VMware servers and 
that coincidence works well, i have installed new fresh centos VM, 
downloaded nut, installed, tried ups on
DELL T130 USB 2.0 - nut driver fails to autostart, after 2-3 manual starts 
it runs, also tried maxretry+ retrydelay also with no difference, ups 
plugged in USB 3.0, VM usb root hub also 3.0 too and it works!


HP PROLIANT ML110 gen6?or5? + usb addon card 1.1 in PCI slot so i tried 1.1 
first - and ups fails with allmost same results, also tried to plug ups into 
onboard usb 2.0 and leave usb 2.0 root hub in VM - FAILS! so removed VM 
usb2.0 and added VM usb3.0 hub and ups works great! also i entered into HP 
bios and switched USB form 2.0 to 1.1 starndard, booted and tested results 
in VM (onboard forced to 1.1usb and VM usb 3.0hub) runs automaticaly but 
sometimes ups disconnects, also i switched VM usb to 2.0 and fails again!


unknown DELL rackmount with i5-7500 8g ram - usb 2.0 with VM usb 2.0 fails, 
usb 2.0 with VM usb 3.0 fails/disconnects, usb 3.0 with VM usb 2.0 fails, 
usb 3.0 with VM usb 3.0 runs OK



so it looks like some problem with VM ESXi 2.0 HUB but also with slower 
speed native USB hubs and/or combinations,
hope this helps anyone trying to run big BackUPS on ESXi - also note i have 
BackUPS 1500 BLACK - newer and there are no problems
with this newer black model - this one works well same as SmartUPS 1000, 
SmartUPS1500, SmartUPS750


dunno if NUT developers can solve this issue somehow, but after week of 
problems this looks like workaround.

According to this, your UPS is using the slowest possible USB 1.1 signaling 
rate, so success after changing from a 2.0 to a 3.0 port might just be 
coincidence:

Also, if you are having intermittent trouble with drivers, you can use the 
maxrestart and retrydelay options: 
http://networkupstools.org/docs/man/ups.conf.html


We have had some reports of issues with VMware and USB. This can affect 
systems with APC UPSes, because the driver needs to be able to pull the 
model number to apply model-specific fixes. Versions after NUT 2.7.2 have a 
partial fix for this, but in your case, you should be able to automatically 
retry with the aforementioned options.=
