Hi,

The only one thing you haveto do is
1. to export/inport this VG change and
2. to update the appropriate .cntl file.

1. On the computer where the VG is not activated you do the following:
ls -ls /dev/vgora/group
and remember its minor (e.g. Ox0N0000)
strings /etc/lvmtab
and remember the disks, which belong to the VG (e.g. /dev/dsk/cXXXX and /dev/dsk/cYYYY)
vgexport vgpora
mkdir /dev/vgora
mknod /dev/vgora/group c 64 0x0N0000
vgimport /dev/vgora /dev/dsk/cXXXX /dev/dsk/cYYYY
2. Edit the cntl file, which belongs to the package, which mounts the new file system and add the following:

LV[K]-/dev/vgora/lvol13; FS[K]=/vghist
and
create the directory: mkdir /vghist; chown oracle /vghist
