disk returns to Fault Tolerant status. For RAID 50 virtual disks, if more than one
sub-vdisk becomes critical, reconstruction and use of vdisk spares occur in the order
sub-vdisks are numbered.
Although using a vdisk spare is the most secure way to provide spares for your
virtual disks, it is also expensive to keep a spare assigned to each virtual disk. An
alternative method is to enable dynamic spares or to assign one or more unused
drives as global spares.
8. Select a drive to be the spare and click Continue.
9. For the number of volumes, select 1.
Notice that by default the volume will not be presented to (accessible by) hosts.
10. Click Create Virtual Disk.
A page is displayed that shows the progress of initializing the virtual disk.
11. Click the link to create another virtual disk.
12. Repeat Step 2 to Step 10 to create a second virtual disk with a different name.
Mapping a Data Host to a Volume
To enable a data host to access a volume you created, you must map the volume to
the host. The port World Wide Name (WWN) of each host connected to the system
is automatically added to the system's global host port list.
Before mapping a data host to a volume you must identify the data host's port
WWN and a LUN that the host is not using.
To map a data host to a volume:
1. Select Manage > Volume Management > Volume Mapping > Map Hosts To Volume.
Notice that your first virtual disk and its volume are selected, and the volume's host
mapping values are set to None.
2. In the Add or Modify a Mapping panel:
a. Select the host WWN value that you identified before beginning.
b. Type the LUN.
c. Leave the access type set as read-write.
d. Select all ports.
e. Click Map It.
