Migratepv-Commad
- Thread starter AIX5L

Yes, you can use migratepv to move the lvs from one hdisk to another, but the new disk must be part of the same volume also.
Another command you might want to consider is cplv.
when using any of the migrate commands (migratepv, migratelp), mirrors are created, then the lvs are resynchronized and then the orginal lvs are removed. You will also need to reassign the dump device using sysdumpdev when using the migratepv.
To avoid this, you can use the cplv, although the new hdisk will also need to be a part of the volume group and your limited to copying each lv one by one.
Can anyone else add any more info?
Hope this helps. Regards,

And what volume group is hdisk5 in?
To copy the contents of logical volume fslv03 to a new logical volume in volume group vg02, enter:
cplv -v vg02
fslv03
Migratepv must have All physical volumes within the same
volume group.
Or back it up , create lvs, and restore it in whatever volume group hdisk5 will be in....
AIX5L,
To avoid using cplv (which does span filesystems as Aixqueen so rightly said) and hacking /etc/filesystems to add in the filesystem stanza, you could do an interactive copy.
i.e. on hdisk5
create a filesystem called transfer, mount it up...
cd into the source directory :
find . -print |backup -ivf - |(cd /transfer; restore -xf -)
This will backup and restore the filesystem interactively. Then change the mount points so that /transfer is the original filesystem name.
Simple. You could also use cpio:
i.e.
find . -print |cpio -pudvm /transfer
