HP XP24000/XP20000 Virtual LVI/LUN (VLL) and Volume Shredder User Guide (T5214-96094, November 2011)

12. To apply the changes to the storage system, click Apply (or Cancel to cancel them).
While an LDEV is being formatted, a progress window opens. The percentage of completion
displayed might be 0% or 99%. This completion percentage could remain visible while the
format operation is in progress.
If desired, you can make settings on the Make Volume function (see “Re-creating the CVs After
Initializing the VDEV (Make Volume Operation)” (page 67)) before clicking Apply. If you click
Apply after making settings on both the Volume Initialize function and the Make Volume
function, the settings on these functions will be applied simultaneously to the storage system.
13. Click OK to complete the process.
When the Volume Initialize operation starts, a notation appears across the bottom of the
window to indicate the progress and to indicate completion at the end of the operation.
When the Volume Initialize function or the Make Volume function is performed, the alias
information that is set to the recreated LDEV by these operations is also deleted. If you set the
alias to the LDEV, you must migrate the alias information to another LDEV before the Volume
Initialize function or the Make Volume function is performed, or you must reconfigure the alias
after the Volume Initialize function or the Make Volume function is performed.
Re-creating the CVs After Initializing the VDEV (Make Volume Operation)
WARNING! The Make Volume function is a destructive operation. The data on the Virtual LVI/LUN
volume being converted is lost when the operation is complete. The user is responsible for backing
up the data as needed before performing this operation.
The Make Volume operation deletes all volumes in a VDEV and creates new variable-sized volumes
(CVs). If necessary, you can create system disks by performing the Install CV operations (see
“Creating System Disks” (page 75)).
When performing Make Volume operations, you can create CVs in the following ways (see
Table 19 (page 67)).
Table 19 Settings for the Make Volume Operation
VLL volume to be createdSettingNo.
A VLL volume that has the specified number of CVs of
the specified capacity is created. This is the same as
the Install CV operation.
Specify the capacity and the number of
variable-sized volumes (CVs) under a VLL volume.
1
A VLL volume that has the specified number of CVs is
created (the VDEV is divided by the specified number).
Specify the number of variable-sized volumes (CVs).2
A VLL volume that has CVs of the specified capacity
is created (the VDEV is divided by the specified
capacity).
Specify the capacity of a variable-sized volume (CV).3
If some space remains in the VDEV after VLL volumes
are created by the settings 1 through 3, that remaining
space can also be converted into a VLL volume.
Specify the remaining capacity for a VLL volume.4
CAUTION: An error message may display if a Volume Initialize operation and a Make Volume
operation are performed concurrently. The part code of this error message is 0003, and the error
number of this error message is 1041. If this message appears, ensure that these operations are
performed separately.
