Steps
1. Back up your data.
2. Delete the virtual disk.
3. Create one or more virtual disks that are smaller than 1TB.
4. Restore your data from backup.
Irrespective of whether your Linux operating system limits the virtual disk size to 1TB, the virtual disk size depends on the version of
the operating system and any updates or modifications that you have implemented. For more information on operating system, see
your operating system documentation.
Problems associated with using the same physical disks for both
redundant and nonredundant virtual disks
When creating virtual disks, you should avoid using the same physical disks for both redundant and nonredundant virtual disks. This applies
to all controllers. Using the same physical disks for both redundant and nonredundant virtual disks can result in unexpected behavior
including data loss.
NOTE: SAS controllers do not allow you to create redundant and nonredundant virtual disks on the same set of physical
disks.
