IBM::SONAS - Perl API to IBM SONAS CLI

VERSION

Version 0.01

SYNOPSIS

IBM::SONAS is a Perl API to IBM SONAS CLI.

        use IBM::SONAS;

        # Create an IBM::SONAS object

        my $ibm = IBM::SONAS->new(      
                                user     => 'admin',
                                host     => 'my-sonas.company.com',
                                key_path => '/path/to/my/.ssh/private_key'
                ) or die "Couldn't create object! $!\n";

METHODS

new ( %ARGS )

        my $ibm = IBM::SONAS->new(      
                                user     => 'admin',
                                host     => 'my-sonas.company.com',
                                key_path => '/path/to/my/.ssh/private_key'
                ) or die "Couldn't create object! $!\n";

Constructor - creates a new IBM::SONAS object. This method accepts three mandatory parameters and one optional parameter, the three mandatory parameters are:

user: The username of the user with which to connect to the device.
host: The hostname or IP address of the device to which we are connecting.
key_path: Either a relative or fully qualified path to the private ssh key valid for the user name and device to which we are connecting. Please note that the executing user must have read permission to this key.

disk ( $id )

        # Get the disk named "system_vol_00" as an IBM::StorageSystem::Disk object

        my $disk = $ibm->disk(system_vol_00);
        
        # Print the disk status

        print $disk->status;

        # Alternately

        print $ibm->disk(system_vol_00)->status;

Returns a IBM::StorageSystem::Disk object representing the disk specified by the value of the id parameter, which should be a valid disk name in the target system.

Note that this is a caching method and that a previously retrieved IBM::StorageSystem::Array object will be returned if one has been cached from previous invocations.

get_disk( $id )

This is a functionally equivalent non-caching implementation of the disk method.

get_disks

        # Print a listing of all disks in the target system including their name, the assigned pool and status

        printf( "%-20s%-20s%-20s\n", 
                "Name", 
                "Pool", 
                "Status" 
        );
        printf( "%-20s%-20s%-20s\n", 
                "-----", 
                "------", 
                "-------" 
        );

        foreach my $disk ( $ibm->get_disks ) { 
                printf( "%-20s%-20s%-20s\n", 
                        $disk->name, 
                        $disk->pool, 
                        $disk->status 
                ) 
        }

        # Prints something like:
        #
        # Name                Pool                Status              
        # -----               ------              -------             
        # silver_vol_00       silver              ready               
        # silver_vol_01       silver              ready

                'Name', 
                'Path', 
                'Protocol', 
                'Active' 
        );

        foreach my $export ( $ibm->get_exports ) { 
                print '-'x55,"\n";
