An attempt to contact the drive with a given device name failed. This probably means the device name is incorrect, but this attempt can also fail for other reasons.
Operation failed.
The device parameter is probably not valid. This could be temporary, but not necessarily. If this occurs while upgrading from Tivoli® Storage Manager Version 4.1 or previous (where paths were not used), then the drive needs to be deleted, redefined, and a new path needs to be defined with a valid device parameter. If this occurs on a Tivoli Storage Manager server that already has paths (Version 4.2 or higher), then just update the drive to online. The device parameter on the drive path can also be updated before the drive is turned online, if you know the device parameter should be changed.
