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 Non-Redundant 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.

Physical Disk Is Offline Or Displays An Error Status
A physical disk may display an error status if it has been damaged, is offline, or was a member of a virtual disk that has been deleted or
initialized. The following actions may resolve the error condition:
• If a user has changed the status to Offline, then return the disk to Online status by performing the Online disk task.
• Investigate whether there are any cables, enclosure, or controller problems preventing the disk from communicating with the
controller. If you find a problem and resolve it and disk does not return to Online or Ready status, reboot the system.
• If the disk is damaged, replace it.
Receive A Bad Block Alert With Replacement, Sense, Or
Medium Error
The following alerts or events are generated when a portion of a physical disk is damaged:
• 2146
• 2147
• 2148
• 2149
• 2150
This damage is discovered when the controller performs an operation that requires scanning the disk. Examples of operations that may
result in these alerts are as follows:
