4.4 Disk roaming
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.
