MVC Shows Invalid Status Of 'Mounted' When The Tape Has Been Ejected From The Library (Doc ID 1616684.1)

Last updated on JUNE 12, 2018

Applies to:

Sun StorageTek Host Software Component (HSC) - Version 6.2 and later
Sun StorageTek Virtual Tape Control Software (VTCS) - Version 6.2 and later
Sun StorageTek Enterprise Library Software (ELS) - Version 7.0 and later
IBM z/OS on System z


This is to document the rare possibility of an MVC having a corrupted status of 'Mounted' and its effect when using VOLPARM to delete an MVC range that includes the MVC volser.

An MVC has a corrupted status of 'Mounted' when in fact it is not. The tape can be ejected from the Library and still have the Mounted status remain.  Somewhere in the past, an MVC status got corrupted and it kept the status of 'Mounted' when in fact it was not.  There is no utility to correct this status. This corrupted status can cause VOLPARM to fail when attempting to delete the MVC.
