Use of event triggers not working

Can you provide out of following:

hagrp -display

Mike

Sorry, in perl "\" is a special character which means ignore meaning of next character, so for example if you want to use a double quote you use:

\"

so the double quote is not interpreted as the end of the string, so if you want to use a \ you have to use \\, so you code needs to be:

VCSAG_SYSTEM("net use Z: \\\\server3\\fileshare");

You can test trigger script as follows:

C:\>cd "\Program Files\VERITAS\cluster server\bin\Triggers"

C:\Program Files\VERITAS\cluster server\bin\Triggers>"\Program Files\VERITAS\VRTSPerl\bin\perl.exe" preonline.pl node1 EV MANUAL

# give control back to HAD.

Your batch file did not work properly as you must do a hagrp -online -nopre at the end of the script as in the perl script:

`\"$vcs_home\\bin\\hagrp\" -online -nopre $ARGV[1] -sys $ARGV[0]`;

hagrp online -nopre %2 -sys %1

halog -add "Invoked with system %1, group %2 for reason %3" -sev I -sys %1

Thanks again Mike. I'm not much of perl scripter. :-)

I modified and tried to run first form CLI like below, and it worked fine, share got mounted and SG onlined.

C:\Program Files\VERITAS\cluster server\bin\Triggers>"\Program Files\VERITAS\VRTSPerl\bin\perl.exe" preonline.pl node1 EV MANUAL

However, when I online SG from JAva Console, mounting behaves like running batch file i mentioned before, it mounted share drive but shows disconnected from My Computer though I can access it and SG got onlined.

Tried using vmware environment, results still the same. could it be credential issue?

Also, i tried using postoffline.pl to unmount after offline and it offlined SG but did not unmount (when i mount it using CLI above). I just appended below lines to postoffline.pl script, the syntax running from CLI is "net use Z: /DELETE".

I tried to run postoffline.pl script manually from CLI (after mounting it via preonline.pl using CLI as well) and it did unmount the drive properly, though it did not offline SG but that's OK since i don't have offline command onpostoffline.pl.

Why is it that when it executed from CLI it works but not from VC Manager Java Console? any difference there?

The PreOnline can used to make a decision about whether to online the service group, so suppose EV will not work without Z been mounted then the code can be something like:

$return_code=0;
$group = $ARGV[1];
if ($group eq "EV") {
    $return_code=VCSAG_SYSTEM("net use Z: \\server3\fileshare");
}

if ($return_code eq 0) {
    if (defined $ARGV[3]) {
        `\"$vcs_home\\bin\\hagrp\" -online -nopre $ARGV[1] -sys $ARGV[0] -checkpartial $ARGV[3]`;
        exit;
    }
    `\"$vcs_home\\bin\\hagrp\" -online -nopre $ARGV[1] -sys $ARGV[0]`;
}
else {
    VCSAG_LOG_MSG ("E", "Mount of Z: failed, so not onlining EV",9000 )
}
exit;

So that is why Preonline requires "hagrp -online -nopre" in the code and why if you run manually the group will be onlined.  All other trigger scripts just run and do not effect onlining or offlining service groups,  so don't required any "hagrp" commands which is why if you run a postoffline manually, it will not offline the group.

The difference in running script manually and through VCS, is that manually you are running script as a "logged in user" to your session, whereas when VCS runs it, it is being run by the "non-logged in user" that the "had" service runs as.

I have seen before that if you are using Terminal services that if a drive is assigned by VCS, My Computer doesn't see it but it is there and if you log out of terminal services session and back in, then it sees it.  I guess this is an issue with terminal services, something like, where it doesn't expect a drive to arrive where a command was not issued in it's session.  I think when a drive is assigned via the MountV resource, Terminal serivce DOES see it, so there is probably some extra coding to make this happen in the MountV agent.

Thanks Mike for the script. I supposed i can just cut & paste this to preonline.pl and test.

This code was an example if EV MUST have Z:

So if EV will work partially without Z: then I would not fail the online of the EV group if mount Z: fails, but if EV will not work at all without Z:, then yes you should copy this code into your script.

If mount does fail, I would give error code in log, like:

Thanks Mike, I tried but same thing. When I online via Java SG went online but the drive was mounted with a red x & shows disconnected and yet it can be accessed normally. At this point it cannot be unmounted and have to reboot to clear the mount. If I execute the online trigger via CLI it went perfectly fine. I have to use Java of course, and this is my dilema now.

Are you using terminal services or do you have console access  - I have only seen this sort of behaviour with terminal server access.   If you are using terminal services, try logging user out and logging back in again.

Have you tried umounting by implementing postoffline trigger so that trigger is called when you offline service group?

What shows red x - is this VEA?
