The LU is not removed from HDLM-management even if the error occurs on all the
paths to the LU, all the paths to the LU are disconnected, or the LU is deleted. The
status of the paths is either
Offline(E)
or
Online(E)
. This operation is equal to
the operation in HDLM 05-01 or earlier. The

do not want to use the LU deletion function and you want the system to operate as it
did in HDLM 05-01 and earlier.
on
The LU is removed from HDLM-management when all the paths to the LU are
disconnected. However, if an
Offline(C)
path is included in the disconnected
paths, the LU is not deleted from HDLM-management.
The deleted LU is restored when it is recovered from the physical failure and the disk
is re-scanned.
on -force
The LU is removed from HDLM-management when all the paths to the LU are
disconnected, even when an
Offline(C)
path is included.

is re-scanned.
