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
