3. Select disks to include in the vdisk. Only available disks have checkboxes. The number of disks you can select is determined by the RAID level, and is specified in the Disk Selection Sets table. When you have selected enough disks, a checkmark appears in the table's Complete field. 4. Click Create Vdisk. If the task succeeds, the new vdisk appears in the Configuration View panel. Deleting vdisks CAUTION: Deleting a vdisk removes all of its volumes and their data. To delete vdisks 1. Verify that hosts are not accessing volumes in the vdisks that you want to delete. 2. In the Configuration View panel, either: • Right-click the system or Vdisks and then select Provisioning > Delete Vdisks. • Right-click a vdisk and select Provisioning > Delete Vdisk. 3. In the main panel, select the vdisks to delete. To select or clear all vdisks, toggle the checkbox in the heading row. 4. Click Delete Vdisk(s). A confirmation dialog appears. 5. Click Delete to continue; otherwise, click Cancel. If you clicked Delete, a processing dialog appears. As vdisks are deleted they are removed from the table and from the Configuration View panel. When processing is complete a success dialog appears. 6. Click OK. Managing global spares You can designate a maximum of eight global spares for the system. If a disk in any redundant vdisk (RAID 1, 3, 5, 6, 10, 50) fails, a global spare is automatically used to reconstruct the vdisk. At least one vdisk must exist before you can add a global spare. A spare must have sufficient capacity to replace the smallest disk in an existing vdisk. The vdisk remains in Critical status until the parity or mirror data is completely written to the spare, at which time the vdisk returns to Fault Tolerant status. For RAID-50 vdisks, if more than one sub-vdisk becomes critical, reconstruction and use of spares occur in the order sub-vdisks are numbered. To change the system's global spares 1. In the Configuration View panel, right-click the system and select Provisioning > Manage Global Spares. The main panel shows information about available disks in the system. Existing spares are labeled GLOBAL SP. • In the Disk Sets table, the number of white slots in the Disks field shows how many spares you can add. • In the enclosure view or list, only existing global spares and suitable available disks are selectable. 2. Select spares to remove, disks to add as spares, or both. 3. Click Modify Spares. If the task succeeds, the panel is updated to show which disks are now global spares. 60 Provisioning the system

Provisioning the system
3.
Select disks to include in the vdisk. Only available disks have checkboxes. The number of disks you can
select is determined by the RAID level, and is specified in the Disk Selection Sets table. When you have
selected enough disks, a checkmark appears in the table's Complete field.
4.
Click
Create Vdisk
. If the task succeeds, the new vdisk appears in the Configuration View panel.
Deleting vdisks
CAUTION:
Deleting a vdisk removes all of its volumes and their data.
To delete vdisks
1.
Verify that hosts are not accessing volumes in the vdisks that you want to delete.
2.
In the Configuration View panel, either:
•
Right-click the system or
Vdisks
and then select
Provisioning > Delete Vdisks
.
•
Right-click a vdisk and select
Provisioning > Delete Vdisk
.
3.
In the main panel, select the vdisks to delete. To select or clear all vdisks, toggle the checkbox in the
heading row.
4.
Click
Delete Vdisk(s)
. A confirmation dialog appears.
5.
Click
Delete
to continue; otherwise, click
Cancel
. If you clicked Delete, a processing dialog appears. As
vdisks are deleted they are removed from the table and from the Configuration View panel. When
processing is complete a success dialog appears.

Managing global spares
You can designate a maximum of eight global spares for the system. If a disk in any redundant vdisk (RAID
1, 3, 5, 6, 10, 50) fails, a global spare is automatically used to reconstruct the vdisk. At least one vdisk
must exist before you can add a global spare. A spare must have sufficient capacity to replace the smallest
disk in an existing vdisk.
The vdisk remains in Critical status until the parity or mirror data is completely written to the spare, at which
time the vdisk returns to Fault Tolerant status. For RAID-50 vdisks, if more than one sub-vdisk becomes
critical, reconstruction and use of spares occur in the order sub-vdisks are numbered.
To change the system's global spares
1.
In the Configuration View panel, right-click the system and select
Provisioning > Manage Global
Spares
. The main panel shows information about available disks in the system. Existing spares are
labeled GLOBAL SP.
•
In the Disk Sets table, the number of white slots in the Disks field shows how many spares you can
add.
•
In the enclosure view or list, only existing global spares and suitable available disks are selectable.
2.
Select spares to remove, disks to add as spares, or both.
3.
Click
Modify Spares
. If the task succeeds, the panel is updated to show which disks are now global
spares.
