Topic: Nut and APC Smart-UPS 1000i

[nigeltodd]

Having managed to stuff my config up, I have since found a multitude of conflicting posts as to how to repair it. Does anyone have any idea how to reset nut to defaults (or uninstall/reinstall it) and then configure it for the smart ups connected via serial cable.

There are differing posts about Model, Type, device etc, which only confuse the issue further for me.

Any thoughts?

Thanks in advance

It would help if you told us what cable came with the ups (eg. 940-0095A).  The cable number can usually be found on the serial connector.

What serial port is it connected to? (eg ttyS0, ttyS12, etc)

Also, tell us your current nut configuration by showing the output of:

config show nut

[nigeltodd]

[root@gateway ~]# config show nut
nut=service
    Cable=940-0024C
    Device=/dev/ttyS0
    MasterPass=887638619708926
    Model=apcsmart
    SlavePass=979090968004555
    status=enabled
[root@gateway ~]#

I need to double check cable and port when i get home - I have tried both ttyS0 & ttyS1 - permissions are crw_cr____ for both, owne ris root, grpoup is uucp.

hope this helps

Cable is not a valid db setting. It won't do anything and the apcsmart driver expects that cable by default anyway. You can remove it if you want but it doesn't matter,

config delprop nut Cable

The rest of the configuration looks correct for that type of UPS/cable combination.

Are you sure your comm port(s) are enabled in your server's bios settings?

Did you?:

expand-template /etc/sysconfig/ups
expand-template /etc/ups/*
/etc/rc7.d/S38nut stop
*wait 5 seconds*
/etc/rc7.d/S38nut start

That sometimes doesn't always do the trick and you need to reboot so to be on the safe side you should:

signal-event post-upgrade
signal-event reboot

There are differing posts about Model, Type, device etc, which only confuse the issue further for me.

Did you look in the documentation?

http://wiki.contribs.org/Uninterruptable_Power_Supply

and more specifically for APC devices using a serial connections:

http://wiki.contribs.org/APC_Serial_UPS

The second link also provides information about setting your serial port up as a symlink, read it carefully as it is a bit confusing at first glance.

All fixed now I think!!

Once I inspected the cable, I discovered it was no longer connected to the UPS!! restarted S38nut - all ok - although I do ghet a battery low message when I start S38nut
 This is output from upsc UPS@localhost

Will see how it stands up in next few days, and will force a power outage for testing.

Does anyone have any idea how to reset nut to defaults

config delete nut
signal-event post-upgrade
signal-event reboot

Note that 'default' for nut is configured for USB connection, but disabled.

[nigeltodd]

OK- once more .....
I have deleted the nut from the config as  per CharlieBrady's instruction - but how do i get it back now?

Thanks Mary,

However I should have added the following :

When I do the following:
{
[root@gateway ~]# config show nut
[root@gateway ~]# config setprop nut Device /dev/ttyS0
[root@gateway ~]# config setprop nut Model apcsmart
[root@gateway ~]# config setprop nut status enabled
[root@gateway ~]# config show nut
[root@gateway ~]#
}
I get no output from the show command. Somehow the nut config is not being saved.

I have been trhought the expand-template commands, and started the servuce - which fails with a "Driver Error 1".

then -
  signal-event post-upgrade
  signal-event reboot
makes no difference either

This all occurred after i did the "config delete nut" command.

What i suspect I need to do is to re-install  nut, and then perform the configuration, hence the 'how do I get it back' question.
I have searched through yum and rpm, but have not been able to find any way to remove and/or update it for sme.

Hopefully someone will have an answer?

Thanks,

Nigel

As you have previously deleted the service then first do
config set nut service
then
config setprop nut Device /dev/ttyS0
config setprop nut Model apcsmart
config setprop nut status enabled
config show nut

[nigeltodd]

Thanks again Mary,

The set nut service has rebirthed the nut entries ok now.

Now when I go through the expand-templates I get the following:

[root@gateway ups]# config show nut
nut=service
    Device=/dev/ttyS0
    Model=apcsmart
    status=enabled

[root@gateway ups]# expand-template /etc/sysconfig/ups

[root@gateway ups]# expand-template /etc/ups/ups*

Getting closer at least!

Any thoughts? the HowTo's etc don't cover these situations alas!
I have also seen a message regarding the worng version of mONITOR Suggests upgrading it) and no user found in ups.users.

Should I add the previous entries as shown above?

Sorry the
config set nut service
command is not enough to fix your issues.

It looks like you have a custom template that is creating problems. Delete it.

rm /etc/e-smith/templates-custom/etc/ups/ups.conf

Then please as Charlie has advised do
config delete nut
signal-event post-upgrade
signal-event reboot

Don't just do expanding of templates as you have obviously been playing with your system and a post-upgrade is needed.
Default values should be reinstated after this, so again issue your setprop commands

config setprop nut Device /dev/ttyS0
config setprop nut Model apcsmart
config setprop nut status enabled

and to avoid further problems do
signal-event post-upgrade
signal-event reboot
