disable the function. For the -pathid parameter, specify an LU, or the ID of a

Setting Up the LU Deletion Function
For details on the LU deletion function, see
The following table lists values and descriptions for the LU deletion function.
Table 3-15 LU Deletion Function Values
Values in the set
operation
Description
off
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 off option is
recommended when you 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.
The removed LU is restored after it is recovered from the physical
failure and the disk is re-scanned.
