Creating Virtual Disks
You can use the Virtual Disk Wizard to create different types of logical storage
units (called virtual disks) on your subsystem.
You can create the following types of virtual disks:
■ Single-device virtual disks (JBODs)
■ Striped virtual disks (RAID 0)
■ Mirrored virtual disks (RAID 1)
■ Striped mirrored virtual disks (RAID 0+1)
■ Striped parity virtual disks with parity across all drives (RAID 3/5)
Note that the capacity of the smallest member, not the largest, determines the
maximum capacity of RAID-based virtual disks.
■ The maximum capacity of RAID 0 virtual disks is equal to the number of
members times the capacity of the smallest member.
■ The maximum capacity of RAID 1 virtual disks is equal to the capacity of the
smallest member.
■ The maximum capacity of RAID 0+1 virtual disks is equal to the number of
members in one stripe times the capacity of the smallest mirrorset member.
■ The maximum capacity of RAID 3/5 virtual disks is equal to the number of
members minus one times the capacity of the smallest member.
Before you can create virtual disks from a physical device, your controller must
know of the device. You can add devices online without restarting the controller.
This procedure describes how to add a physical device before you create a virtual
disk.
To add a physical device and then create a virtual disk, follow these steps:
1. From the Navigation window, open a Storage window within a desired
subsystem.
2. Click Storage > Device > Add in the Navigation window.
