That's exactly what I'll do, I'll reduce the size of /home as it's huge.
Two things I don't understand though:
1. I deleted a huge 20G SAVSYS from /var/vio/VMLibrary but it didn't free up any PPs on either physical disk. Would I have to delete files then reduce the filesystem using chfs before I see any free PPs?
2. If /var/vio/VMLibrary isn't mirrored how does it appear on both physical disks?
Cheers

NAME
hugetlbfs_find_path, hugetlbfs_find_path_for_size - Locate an appropriate hugetlbfs mount point
SYNOPSIS
#include <hugetlbfs.h>
const char *hugetlbfs_find_path(void);
const char *hugetlbfs_find_path_for_size(long page_size);

default huge page size is used (see gethugepagesize(3)). For hugetlbfs_find_path_for_size, a valid huge page size must be specified (see
gethugepagesizes(3)).
RETURN VALUE
On success, a non-NULL value is returned. On failure, NULL is returned.
