An DETACH is performed automatically in BS2000 for BS2000 devices which are
connected exclusively to the XSB.
The path configuration of PowerPath devices which have a connection to the XSB is
automatically shortened.
A disk mirror which is connected to the XSB is automatically removed from the mirror
disk.
A redundant Solaris network port on the XSB is automatically deactivated in IPMP.
A redundant ZASLAN network port on the XSB is automatically deactivated in BCAM.
Alternate path are switched to.
