The lvm routines return vgid but not vgname. Since commands like
lsvg and getvgname return vgname I suppose there is a way to do this
programmatically. Could you please illustrate how?
---------- ---------- ---------- --------- ---------- ----------
A: The LVM subroutines access the VGDA to get its information. Since the
VGDA does not contain any reference to the VG's name, the LVM
subroutines will not be able to return that information.
The only place where the VG name is stored is in the ODM. In your
program, once you obtain the VGID, you can use ODM subroutines to
query for the VG name whose ID is the specified VGID.
With a shell script, this can be easily accomplished with the "odmget"
command. Since the ODM contains all of the VGID's for all the
volume groups, you may not even need to use the LVM subroutines to
accomplish your goal -- just the ODM subroutines.
For more information, please refer to the InfoExplorer section
entitled: "Object Data Manager (ODM) Overview for Programmers".
Another solution that may be easier to implement, but may not be quite
as nice is to use the system() call to either lsvg or getvgname,
and dump the output to a file. From there, you can use C functions to
parse this and get the information you require.
