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

Tips
The size of UDV extension must be larger than original.
Caution
UDV Extension cannot be executed during rebuild or migration.
Physical disks can be re-sequenced in the same system or move whole physical
disks from system-1 to system-2. This is called disk roaming. Disk roaming has
some constraints as described in the following:
1. Check the firmware of two systems first. It is better that both have
same firmware version or newer.
2. Whole physical disks of related VG should be moved from system-1 to
system-2 together. The configuration of both VG and UDV will be kept
but LUN configuration will be cleared to avoid conflict with system-2.
