AIX with 2 Net Interfaces lose connectivity
hi guys
We have a AIX Server with TSM installed.
This server has en0 for administration purposes and we have en1 for backup stuff.
en0 subnet 10.10.10.x
en1 subnet 10.10.20.x
The issue we are having is all of a sudden the LPARs we are backing up lose connectivity to the AIX-TSM Server. for example
en1 ip is 10.10.20.10 and a TSM LPAR client that we are backing up is 10.10.20.11
Backup fails and we found that LPAR client 10.10.20.11 won't ping 10.10.20.10, but if go to the AIX-TSM server ping works and ping from LPAR client is back.
It's like ping from the AIX-TSM box reactivates connectivity.
Something important to mention we found the problem making backups but today we were doing to test and the connectivity is gone doing nothing and pinging from AIX-TSM server to LPAR Clients reactivates it
Anyone has seen an issue like this?
en0 is always fine
thanks a lot

net::subnets
Net::Subnets(3pm) User Contributed Perl Documentation Net::Subnets(3pm)
NAME
Net::Subnets - Computing Subnets In Large Scale Networks
SYNOPSIS
use Net::Subnets;
my $sn = Net::Subnets->new;
$sn->subnets(@subnets);
if (my $subnetref = $sn->check($address)) {
...
}
my ($lowipref, highipref) = $sn->range($subnet);
my $listref = $sn->list(($lowipref, $highipref));
DESCRIPTION
Very fast matches large lists of IP addresses against many CIDR subnets and calculates IP address ranges.
This is a simple and efficient example for subnet matching:
use Net::Subnets;
my @subnets = qw(10.0.0.0/24 10.0.1.0/24);
my @addresses = qw/10.0.0.1 10.0.1.2 10.0.3.1/;
my $sn = Net::Subnets->new;
$sn->subnets(@subnets);
my $results;
foreach my $address (@addresses) {
if (my $subnetref = $sn->check($address)) {
$results .= "$address: $$subnetref
";
}
else {
$results .= "$address: not found
";
}
}
print($results);
This is a simple example for range calculation:
use Net::Subnets;
my @subnets = qw(10.0.0.0/24 10.0.1.0/24);
my $sn = Net::Subnets->new;
my $results;
foreach my $subnet (@subnets) {
my ($lowipref, $highipref) = $sn->range($subnet);
$results .= "$subnet: $$lowipref - $$highipref
";
}
print( $results );
This is a simple example for list generation:
use Net::Subnets;
my $lowip = '192.168.0.1';
my $highip = '192.168.0.100';
my $sn = Net::Subnets->new;
my $listref = $sn->list(($lowip, $highip));
foreach my $address (@$listref) {
# do something cool
}
METHODS
"new"
my $subnets = Net::Subnets->new;
Creates an "Net::Subnets" object.
"subnets"
$subnets->subnets([qw(10.0.0.0/24 10.0.1.0/24)]);
The C<subnets> method lets you prepare a list of CIDR subnets.
"check"
my $match = $subnets->check($address);
The C<check> method lets you check an IP address against the previously
prepared subnets.
"range"
my ($lowest, $highest) = $subnets->range($subnet)
The C<range> method lets you calculate the IP address range of a subnet.
"list"
my $list = $subnets->list($lowest, $highest);
The C<list> method lets you calculate a list containing all IP addresses
in a given range.
