254 Virtual Disks
Considerations for Concatenated to RAID 1 Reconfiguration on CERC SATA1.5/6ch
Controllers
When reconfiguring a concatenated virtual disk to a RAID 1 on a CERC
SATA1.5/6ch controller, the reconfigured virtual disk may display the
Resynching state. When reconfiguring from a concatenated virtual disk to a
RAID 1, data is copied from the single concatenated disk to the RAID 1
mirror. The controller perceives this operation as similar to resynching a
mirror, and therefore may display the Resynching state.
Performing a controller rescan during the virtual disk reconfiguration may
also cause the virtual disk to display a Resynching state.
While the virtual disk displays a Resynching state, the Pause Check
Consistency and Cancel Check Consistency tasks is available. Executing
either of these tasks on the virtual disk while it is in Resynching state causes
the virtual disk to be in a Failed Redundancy state.
Format and Initialize; Slow and Fast Initialize
Does my controller support this feature? See Supported Features.
The Format or Initialize task erases the files and removes the file systems on
virtual disks while keeping the virtual disk configuration intact. Formatting or
initializing a virtual disk destroys all data on the virtual disk. If the boot
partition resides on the virtual disk, it is destroyed by the format operation.
Some controllers have BIOS settings for a fast initialize or a slow initialize. In
this case, the Initialize task performs the type of initialization (fast or slow)
that is specified in the BIOS.
Other controllers have a Fast Initialize and Slow Initialize task available on
the controller task drop-down menu. For more information, see
Considerations for Fast Initialize and Considerations for Slow Initialize.
NOTE: On a system running Linux operating systems, you cannot format a virtual
disk that contains a mounted volume.
Considerations for Format
The format task applies to the CERC SATA1.5/6ch controllers. After the
format is initiated, it cannot be cancelled.
