Sorry, it took me a while longer than i thought to come back to here:
you look for an existing device file as a test if the VG is online. You should use the AIX methods instead, because they always work, while this may or may not work. Use
to get a list of online VGs. Change your test accordingly. Then
Even if this would be syntactically correct (which it isn't, see posts above) it would be better to use normal AIX methods to get a list of LVs in a VG. Use

I've looked a little but haven't found a solid answer, assuming there is one.
What's better, hardware mirroring or ZFS mirroring? Common practice for us was to use the raid controllers on the Sun x86 servers. Now we've been using ZFS mirroring since U6. Any performance difference? Any other... (3 Replies)

io::async::detachedcode
IO::Async::DetachedCode(3pm) User Contributed Perl Documentation IO::Async::DetachedCode(3pm)NAME
"IO::Async::DetachedCode" - execute code asynchronously in child processes
SYNOPSIS
This object is used indirectly via the "IO::Async::Loop"'s "detach_code" method.
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $code = $loop->detach_code(
code => sub {
my ( $number ) = @_;
return is_prime( $number );
}
);
$code->call(
args => [ 123454321 ],
on_return => sub {
my $isprime = shift;
print "123454321 " . ( $isprime ? "is" : "is not" ) . " a prime number
";
},
on_error => sub {
print STDERR "Cannot determine if it's prime - $_[0]
";
},
);
$loop->run;
DESCRIPTION
This object class provides a legacy compatibility layer for existing code that tries to construct such an object. It should not be used for
new code; see instead the IO::Async::Function object, for which this is now a wrapper.
CONSTRUCTOR
$code = $loop->detach_code( %params )
This function returns a new instance of a "IO::Async::DetachedCode" object. The %params hash takes the following keys:
code => CODE
A block of code to call in the child process.
stream
marshaller
These arguments are no longer used; any values passed will be ignored.
workers => INT
Optional integer, specifies the number of parallel workers to create.
If not supplied, 1 is used.
exit_on_die => BOOL
setup => ARRAY
Passed through to the underlying "IO::Async::Function" object.
METHODS
$code->call( %params )
Calls one invocation of the contained function code block. See the "call" method on "IO::Async::Function" for more detail.
$code->shutdown
This method requests that the detached worker processes stop running.
$n_workers = $code->workers
This method in scalar context returns the number of workers currently running.
@worker_pids = $code->workers
This method in list context returns a list of the PID numbers of all the currently running worker processes.
