=head3 getGroupMembers
Get the list of members for the specified group.
Arguments:
Returns:
undef - error
$members - comma-separated list of group members
Globals:
Error:
Example:
To use:
- create hash for objectname and and attr values (need group
name (object), and grouptype & members attr values at a
minimum.)
ex. $objhash{$obj}{$attr} = value;
- then call as follows:
xCAT::DBobjUtils->getGroupMembers($objectname, \%objhash);
