SYNOPSIS

IBM::V7000Unified is a Perl API to IBM V7000 Unified CLI.

METHODS

new

        my $ibm = IBM::V7000Unified->new(      
					user            => 'admin',
                                        host            => 'my-v7000-unified.company.com',
                                        key_path        => '/path/to/my/.ssh/private_key'
                        ) or die "Couldn't create object! $!\n";

Constructor - creates a new IBM::V7000Unified 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.

The optional parameter is:

stats_threshold: The period in seconds for which retrieved system statistics will be considered fresh, after which they will be re-retrieved. If not set, the default value of this parameter is zero meaning that the statistics are not refreshed unless done explicitly via the refresh method of an IBM:StorageSystem::Statistic object.

refresh_system_stats

This method refreshes all system statistics with updated values from the system. This method may be handy if instantiate an IBM::StorageSystem object within a long running or non-exiting process and wish to either periodically retrieve updated system statistics.

Note that you can call refresh on individual system statistics which may have a slight performance increase over this method.

stats_threshold

This method allows you specify the statistics threshold freshness interval in seconds. This interval is used to determine if the value sreturned by a statistics method are fresh or whether they should be refreshed from the atregt system.

By default this value is zero, meaning that the statistics are never refreshed unless explicitly done so by calling the reefresh method of the statistic object. This may result in a performance increase in situations where statistic methods are frequently used, and may also result in more consistent reporting of the target system state as the statistic values will more closely represent a single point in time overview of the system rather than a series of consecutive snapshots.

In situation where you may want to gather a set of statistical values for the target system over a finite period, you could set the threshold value low, and reset it afterwards. e.g.

# Print the current FC IOPS value every two seconds for a minute
$ibm->stats_threshold = 1;
for ( 1 .. 30 ) {
	print $ibm->fc_io_current;
	sleep 2
}
# Disable automatic refreshing
$ibm->stats_threshold = 0;

array( $id )

# Print the capacity and RAID level of array 1 in GB
my $array = $ibm->array( 1 );
print "Array 1 capacity: " . int ( $array->capacity / ( 1024 ** 3 ) )
        . " (" . $array->raid_level . ")\n"

# e.g. Array 1 capacity: 5824G (raid10)

Returns an IBM::StorageSystem::Array object representing the array specified by the numerical id parameter.

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_array( $id )

Returns the array specified by the value of the numerical ID argument as an IBM::StorageSystem:Array object.

Note that this method is non-caching and the array information will always be retrieved from the StorageSystem system even if a cached object exists.

get_arrays

# Print the array status of all arrays in our system
map { print "Array ", $_->mdisk_id, " status ", $_->status, "\n" } $ibm->get_arrays;

Returns an array of IBM::StorageSystem::Array objects representing all arrays in the target system.

disk ( $id )

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

# 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.

get_disk( $id )

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

# -----               ------              -------             
# silver_vol_00       silver              ready               
# silver_vol_01       silver              ready               
# silver_vol_02       silver              ready    
# ... etc.

Returns an array of IBM::StorageSystem::Disk objects representing all disks in the target system.

drive ( $id )

note that this method implements caching and that a cached object will be retrieved if present.

If you require a non-cached object, then use the get_drive method instead.

get_drive( $id )

Returns the drive specified by the value of the integer argument. This method is non-caching and always retrieves information directly from the target system even if a cached object is present.

get_drives( $id )

# Print the SAS port status and drive status for all drives in a nicely formatted list
printf("%-20s%-20s%-20s%-20s\n", 'Drive', 'SAS Port 1 Status', 'SAS Port 2 Status', 'Status');
printf("%-20s%-20s%-20s%-20s\n", '-'x18, '-'x18, '-'x18, '-'x18);
map { printf( "%-20s%-20s%-20s%-20s\n", $_->id, $_->port_1_status, $_->port_2_status, $_->status) } $ibm->get_drives;

# Or alternately;
print "Description: " . $ibm->node( mgmt001st001 )->description . "\n";

Returns the node identified by the value of the node parameter as a IBM::StorageSystem::Node object.

Note that this method implements caching and that a cached object will be returned if one is available. If you require a non-cached object, then please use the non-caching get_node method.
