Hello,
We have a script which when run on the host gives us the status of the internal and SAN attached disks. The output of which is as follows:
Nm DEVICE VEND PROD LunID SYM DevID DISKGROUP SIZE N E
----------------------------------------------------------------------------------------
1. cciss/c0d0 HP LOGICAL VOLUME N/A N/A N/A 68.33 1 1
2. sdb EMC SYMMETRIX 27 7300 251 app_DG 50.58 2 2
----------------------------------------------------------------------------------------
N =Number of Paths (NE =Not Enabled)
E =Number of Currently Enabled Paths
================================================== =======
The requirement now is to create another script which will check the SAN path status from the above script. If the no of Paths shows less than 1 for SAN disks, then I should get an alert that SAN path failed or if all the path is ok, then SAN path is ok.
Thanking in anticipation.
Regards,
Mahive.

Thanks I need to know if my server has dual HBA and if multipath has been configured. For Multipath I ran lspath and it shows all drives and if MPIO is configured for that drive.

Graphics::Primitive::Canvas(3pm) User Contributed Perl Documentation Graphics::Primitive::Canvas(3pm)
NAME
Graphics::Primitive::Canvas - Component composed of paths
DESCRIPTION
Graphics::Primitive::Canvas is a component for drawing arbitrary things. It holds Paths and Operations.
SYNOPSIS
use Graphics::Primitive::Canvas;
my $canvas = Graphics::Primitive::Canvas->new;
$canvas->move_to($point); # or just $x, $y
$canvas->do($op);
DESCRIPTION
The Canvas is a container for multiple Paths. It has a path that is the operative path for all path-related methods. You can treat the
Canvas as if it was a path, calling methods like line_to or move_to.
When you are ready to perform an operation on the path, call the do method with the operation you want to call as an argument. Drawing a
line and stroking it would look like:
$canvas->move_to(0, 0);
$canvas->line_to(10, 10);
my $op = Graphics::Primitive::Operation::Stroke->new;
$stroke->brush->color(
Graphics::Color::RGB->new(red => 0, blue => 1, green => 1)
);
$canvas->do($op);
When you instantiate a Canvas a newly instantiated path resides in path. After you call do that current path is moved to the paths list
and new path is placed in current_path. If you want to keep the path around you can call save before do then call restore to put a saved
copy of the path back into path.
METHODS
Constructor
new Creates a new Graphics::Primitive::Canvas
Instance Methods
do Given an operation, pushes the current path onto the path stack.
FIXME: Example
path
The current path this canvas is using.
path_count
Count of paths in paths.
paths
Arrayref of hashrefs representing paths combined with their operations:
[
{
path => $path,
op => $op
},
]
restore
Replace the current path by popping the top path from the saved path list.
save
Copy the current path and push it onto the stack of saved paths.
saved_paths
List of saved paths. Add to the list with save and pop from it using restore.
saved_path_count
Count of paths saved in saved_paths.
