APAR IC45703 resolves an issue where ACSLS libraries are unable to mount
scratch volumes.  ACLSL libraries will fail to mount scratch volumes,
though private volumes can be successfully mounted.  Any attempt to mount
a scratch volume will fail with the following error:

ANR1405W Scratch volume mount request denied - no scratch volume
available.

If your tape library is ACSLS, please wait to install 5.3.1.0 until
5.3.1.1 is available where this problem is corrected.  We are in the
process of refreshing the README on the FTP site indicating that this
level should not be installed by customers using ACSLS libraries. We
apologize for this inconvenience.
