Method Details [hide private]

__init__(self, name, dev=None)
(Constructor)

source code 

A PSCSIStorageObject can be instantiated in two ways:

  • Creation mode: If dev is specified, the underlying configFS object will be created with that parameter. No PSCSIStorageObject with the same name can pre-exist in the parent PSCSIBackstore in that mode, or instantiation will fail.
  • Lookup mode: If dev is not set, then the PSCSIStorageObject will be bound to the existing configFS object in the parent PSCSIBackstore having the specified name. The underlying configFS object must already exist in that mode, or instantiation will fail.
Parameters:
  • name (string) - The name of the PSCSIStorageObject.
  • dev (string) - You have two choices:
    • Use the SCSI id of the device: dev="H:C:T:L".
    • Use the path to the SCSI device: dev="/path/to/dev".
Returns:
A PSCSIStorageObject object.
Overrides: object.__init__

_configure(self, dev)

source code 
Overrides: StorageObject._configure

_set_wwn(self, wwn)

source code
