Software Multipath
Hello everybody...
I have a Server conected to a Disk Array through 2 canals of FiberChannel... I've installed RedHat Advance Server 3 and of course i see two device files that refer the same disk: for example: /dev/sda and /dev/sdb are refered to the same Lun... This is the same case for a new Solaris Server...
The fiber channel Cards are Emulex in the case of Linux... I know until now that QLogic Cards resolve the multipath issue and there are so many property software Multipath like SecurePath of HP.
Is there any software Multipath in free software Comunity???
Is there any solution Multipath in the comunity???
I hope you can help me..

net::server::multitype
Net::Server::MultiType(3) User Contributed Perl Documentation Net::Server::MultiType(3)
NAME
Net::Server::MultiType - Net::Server personality
SYNOPSIS
use base qw(Net::Server::MultiType);
sub process_request {
#...code...
}
my @types = qw(PreFork Fork Single);
Net::Server::MultiType->run(server_type => @types);
DESCRIPTION
Please read the pod on Net::Server first. This module is a personality, or extension, or sub class, of the Net::Server module.
This personality is intended to allow for easy use of multiple Net::Server personalities. Given a list of server types,
Net::Server::MultiType will require one at a time until it finds one that is installed on the system. It then adds that package to its
@ISA, thus inheriting the methods of that personality.
ARGUMENTS
In addition to the command line arguments of the Net::Server base class, Net::Server::MultiType contains one other configurable parameter.
Key Value Default
server_type 'server_type' 'Single'
server_type
May be called many times to build up an array or possible server_types. At execution, Net::Server::MultiType will find the first
available one and then inherit the methods of that personality
