Dear Caldera Customer,

Support Level Supplement (SLS) ptf7640b, the UnixWare 7.1.0, 7.1.1 vxslicer 
supplement, addresses the following problems.


SLS ptf7640a addresses this issue:

1. The root disk cannot be encapsulated due to a gap between dump and swap. 
   The gap is created during a previous attempt to encapsulate the root drive, 
   and results from the use of swap as a temporary working area during 
   encapsulation. If the swap is large enough, the end track lies beyond the 
   2GB limit from the start of the encapsulation area. Since vxslicer is not 
   large file capable, this can result in transfer errors.

SLS ptf7640b addresses this issue

2. Replacing a failed root disk mirror via vxdiskadm does not make it bootable.
