Disk usage options
The Set Disk Usage command is used to set disk usage options.
It provides the following options:
Reserved for manual use
Disks reserved for manual use are not available in automatic selection operations, including hot relocation. In an automatic selection operation, Storage Foundation for Windows chooses the storage where the operation occurs. Generally, the user is given a choice between allowing SFW to "Auto select disks" or "Manually select disks." Examples of commands that allow automatic selection are New Volume and Add Mirror.
Reserving a disk for manual use lets you prevent any unwanted volumes or subdisks from being placed on that disk and gives you complete control over the disk.
There are three options related to how a disk is used as a target for hot-relocated subdisks. In considering how to mark each disk, remember that the hot relocation operation occurs at the disk group level, and only target disks within the same disk group are considered.
The three options are as follows:
Preferred hot relocation target
If there is an I/O failure anywhere in the system, SFW first looks for space on the disks that have been marked as preferred hot-relocation targets for redundant subdisks.
Secondary hot relocation target
This is the default for all disks. During the hot relocation operation, if there are no disks selected as preferred targets or if there is no space available on those disks, SFW chooses space on disks marked as secondary targets.
Not used as a hot relocation target
This option does not allow any hot-relocated subdisks to be moved to the selected disks. It differs from the "Reserved for manual use" option in that the disk remains available for other automatic selection operations.
To set disk usage
- Right-click on the desired disk.
- Select Set Disk Usage from the context menu.
The Set Disk Usage dialog box appears.
- Choose how you want Storage Foundation for Windows to use the disk.
- When you are satisfied with your selection, click OK.
You can review the settings for all your disks by selecting the Disks node in the tree view and then viewing the Disks tab in the right pane. The settings for each disk are listed in the Reserved and Hot Use columns.
