NAME ^

IBM::StorageSystem::Snapshot - Class for operations with a IBM StorageSystem snapshot objects

VERSION ^

Version 0.01

SYNOPSIS ^

IBM::StorageSystem::Snapshot is a class for operations with a IBM StorageSystem snapshot objects.

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

        # Print a list of all snapshots tabularly ordered by file system and fileset,
        # including the age of each snapshot in days.

        use Date::Calc qw(Today Delta_Days);

        my ( $y, $m, $d ) = Today;

        foreach my $filesystem ( $ibm->get_filesystems ) { 
                print "Filesystem: ". $filesystem->device_name ."\n";
            
                foreach my $fileset ( $filesystem->get_filesets ) { 
                        print "\tFileset : ". $fileset->name ."\n";
            
                        foreach my $snapshot ( $fileset->get_snapshots ) { 
                                my $dd = Delta_Days( ( split /-/, ( split / /, $snapshot->creation )[0], 3 ), $y, $m, $d );
                                print "\t\tSnapshot ID: ". $snapshot->id ." is $dd days old\n"
                        }   
                }   
        }

        # Prints something like:
        # Filesystem: fs1
        #       Fileset : root
        #       Fileset : share-dlf
        #               Snapshot ID: 2790 is 0 days old
        #               Snapshot ID: 2742 is 0 days old
        #               Snapshot ID: 2693 is 1 days old
        #               Snapshot ID: 2645 is 1 days old
        #               Snapshot ID: 2597 is 1 days old
        #               Snapshot ID: 2550 is 1 days old
        #               Snapshot ID: 2456 is 2 days old
        #               Snapshot ID: 2409 is 2 days old
        #               Snapshot ID: 2362 is 2 days old
        #               Snapshot ID: 2314 is 3 days old
        # ... etc.

METHODS ^

device_name

Returns the name of the filesystem on which the snapshot resides (use in combination with the fileset method).

fileset_name

Returns the name of the fileset to which the snapshot applies - this will be null for filesystem level snapshots.

snapshot_id

Returns the snapshot unique ID.

rule_name

Returns the name of the rule which generated the snapshot.

status

Returns the status of the snapshot - either valid or invalid.

creation

Returns the creation time of the snapshot in the format 'YYYY-MM-DD HH:MM:SS'.

used_metadata

Returns the snapshot metadata storage usage in KB.

used_data

Returns the snapshot data storage usage in KB.

id

Returns the snapshot integer ID - note that this may not be unique on the target system.

timestamp

Returns a timestamp in the format 'YYYY-MM-DD HH:MM:SS' at which the snapshot CTDB data was last verified.
