UDV Extension, Tips | APC SCSI-SATA II specification

"Degrade VG not allowed": Source VG is degraded.

Tips

To do migration/expansion, the total size of VG must be larger or equal to the original VG. It does not allow expanding the same RAID level with the same hard disks of original VG.

During setting migration, if user doesn’t setup correctly, controller will pop up warning messages. Below is the detail of messages.

"Invalid VG ID": Source VG is invalid.

"Degrade VG not allowed": Source VG is degraded.

"Initializing/rebuilding operation's going": Source VG is initializing or rebuilding.

"Migration operation's going": Source VG is already in migration.

"Invalid VG raidcell parameter": Invalid configuration. E.g., New VG's capacity < Old VG's capacity, New VG's stripe size < Old VG's stripe size. Or New VG's configuration == Old VG's configuration.

"Invalid PD capacity": New VG's minimum PD capacity < Old VG's minimum PD capacity.

Caution

VG Migration cannot be executed during rebuild or UDV extension.

4.3 UDV Extension

To extend UDV size, please follow the procedures.

1.Select “/ Volume config / User data volume”.

2. Decide which UDV to be extended, click the blue square button

“” in the Size column next the number.

3.Change the size. The size must be larger than the original, then click

““ to start extension.

4.Extension starts. If UDV needs initialization, it will display an “I” in “Status 3” and complete percentage of initialization in “R%”.
