Partitioning

Partition management functions.

lmi.scripts.storage.partition.create_partition(ns, device, size=None, partition_type=None)

Create new partition on given device.

Parameters:
  • device (LMIInstance/CIM_StorageExtent or string) – Device which should be partitioned.
  • size (int) – Size of the device, in blocks. See device’s BlockSize to get it. If no size is provided, the largest possible partition is created.
  • partition_type (int) – Requested partition type. See PARTITION_TYPE_xxx variables. If no type is given, extended partition will be automatically created as 4th partition on MS-DOS style partition table with a logical partition with requested size on it.
Return type:

LMIInstance/CIM_GenericDiskPartition.
lmi.scripts.storage.partition.create_partition_table(ns, device, table_type)

Create new partition table on a device. The device must be empty, i.e. must not have any partitions on it.

Parameters:
  • device (LMIInstance/CIM_StorageExtent) – Device where the partition table should be created.
  • table_type (int) – Requested partition table type. See PARTITION_TABLE_TYPE_xxx variables.
lmi.scripts.storage.partition.delete_partition(ns, partition)

Remove given partition

Parameters:partition (LMIInstance/CIM_GenericDiskPartition) – Partition to delete.
lmi.scripts.storage.partition.get_disk_partition_table(ns, device)

Returns LMI_DiskPartitionTableCapabilities representing partition table on given disk.

Parameters:device (LMIInstance/CIM_StorageExtent or string) – Device which should be examined.
Return type:LMIInstance/LMI_DiskPartitionConfigurationCapabilities.
lmi.scripts.storage.partition.get_disk_partitions(ns, disk)

Return list of partitions on the device (not necessarily disk).

Parameters:device (LMIInstance/CIM_StorageExtent or string) – Device which should be partitioned.
Return type:List of LMIInstance/CIM_GenericDiskPartition.
lmi.scripts.storage.partition.get_largest_partition_size(ns, device)

Returns size of the largest free region (in blocks), which can accommodate a partition on given device. There must be partition table present on this device.

Parameters:device (LMIInstance/CIM_StorageExtent or string) – Device which should be examined.
Return type:int
lmi.scripts.storage.partition.get_partition_disk(ns, partition)

Return a device on which is located the given partition.

Parameters:partition (LMIInstance/CIM_GenericDiskPartition or string) – Partition to examine.
Return type:LMIInstance/CIM_StorageExtent.
lmi.scripts.storage.partition.get_partition_tables(ns, devices=None)

Returns list of partition tables on given devices. If no devices are given, all partitions on all devices are returned.

Parameters:devices (list of LMIInstance/CIM_StorageExtent or list of strings) – Devices to list partition tables on.
Return type:List of tuples (LMIInstance/CIM_StorageExtent, LMIInstance/LMI_DiskPartitionConfigurationCapabilities).
lmi.scripts.storage.partition.get_partitions(ns, devices=None)

Retrieve list of partitions on given devices. If no devices are given, all partitions on all devices are returned.

Parameters:devices (List of LMIInstance/CIM_StorageExtent or list of string) – Devices to list partitions on.
Return type:List of LMIInstance/CIM_GenericPartition.
