When Using NetApp Storage
Using storage management software, the data disk can be accessed from managed servers by defining LUNs of iSCSI boot disk and
of the data disk in the same igroup.
Detaching a Disk
Use the following procedure to detach a disk allocated to an L-Server:
1.
Right-click the target L-Server in the orchestration tree, and select [Change Settings]-[Detach Disk] from the popup menu.
The [Detach a Disk] dialog is displayed.
2.
Select or enter the following items:
Resource List
Select the disk resource to remove from "Resource List". Disk resources other than system disks are displayed in the list.
Delete the selected disk resource (for Physical L-Servers and for Hyper-V Virtual L-Servers)
If a disk resource that has been created from the virtual storage is selected in the [Resource List], then setting can be made with
the following option buttons when reducing disks.
Yes
The disk resources are deleted when they are reduced.
No
Disk resources are not deleted when reducing, and they are registered in the same storage pool as the virtual storage they
were created from.
Detach disks (for Virtual L-Servers)
When detaching disks, check the [Detach disks.] checkbox.
Detach disks when the L-Server is running
When detaching disks while the L-Server is powered on, check the [Detach disks when the L-Server is running.] checkbox.
3.
Click <OK>.
Note
-
When using RHEL-KVM virtual L-Servers, the L-Server must be powered off in order to detach a disk.
-
When using a virtual L-Server on something other than RHEL-KVM, and when detaching a disk resource virtual L-Server on Hyper-
V, the content of the detached disk is deleted. After checking the advisory notes in the displayed dialog, check the [Detach disks.]
checkbox.
-
If disks are detached while the server is powered on, it is necessary to change the status of the disk into unused in advance. After
checking the advisory notes in the displayed dialog, check the [Detach disks when the L-Server is running.] checkbox.
-
When the disk resource is a LUN created in advance or a disk resource for virtual L-Servers, it is recommended to delete the data on
the disk, as the data is not deleted when the disk is detached. For details on how to delete data on the disks, refer to the cautionary
notes of "14.5 Storage
-
When using physical L-Servers, disks or networks cannot be detached from the L-Server that iSCSI boot is being adopted.
-
If [No] is selected for [Detach Selections disks], this setting is only valid for disk resources when reducing. Specifying this does not
allow indefinite saving of disk resources.
-
If they are disk resources that were created with dynamic LUN mirroring, the disk resources on the local site and on the remote site
are deleted simultaneously when the L-Server is deleted.
-
The disk resources detached from a virtual L-Server on Hyper-V can only be saved when using Microsoft(R) System Center 2012
Virtual Machine Manager.
