Is it not possible to backup the complete content of the VG including
all the data of the LPARs?
Thanks in advance!

savevg only only backup files of mounted file systems. To backup the contents of a client partition (sometimes called VIOC to designate it is a virtual machine (aka LPAR) that is dependent on a VIOS for resources).
So, basically, to backup to tape from a client partition you will need to use DLPAR to reassign the tape drive to the client partition if the tape drive based on SCSI. If the TAPE drive is FC connected you need to get the tape drive zoned to the client
partition and run savevg on the client.
Note: savevg does not backup logical volumes that have been assigned as storage to a client partition (so called LVBS - logical volume backed storage).
Hope this helps. And, you may try posting a question on my forums at
