Creare volumi mirrorati con Veritas Volume Manager

Lo scopo e` creare due volumi mirrorati sul DiskGroup rootdg, e si fa in questo modo:
vxassist -g rootdg make lv_mqm 4194304 layout=mirror rootdg01 rootdg02
vxassist -g rootdg make lv_mqm_log 4194304 layout=mirror rootdg01 rootdg02

Bisogna creare il nuovo filesystem sul volume:
newfs /dev/vx/rdsk/rootdg/lv_mqm
newfs /dev/vx/rdsk/rootdg/lv_mqm_log

Ho modificato il file /etc/vfstab:
/dev/vx/dsk/rootdg/lv_mqm /dev/vx/rdsk/rootdg/lv_mqm /var/mqm ufs 1 yes -
/dev/vx/dsk/rootdg/lv_mqm_log /dev/vx/rdsk/rootdg/lv_mqm_log /home/ap/mqm/log ufs 1 yes -

Fatto il backup delle vecchie directory e rimosso i file al loro interno:
cp -r /var/mqm /var/mqm.bck && rm -r /var/mqm/*
cp -r /home/ap/mqm/log /home/ap/mqm/log.bck && rm -r /home/ap/mqm/log/*

Eseguito il mount:
mount /dev/vx/dsk/rootdg/lv_mqm /var/mqm
mount /dev/vx/dsk/rootdg/lv_mqm_log /home/ap/mqm/log

E ripristinato il tutto:
cp -r /var/mqm.bck/* /var/mqm/ && rm -r /var/mqm.bck/
cp -r /home/ap/mqm/log.bck/* /home/ap/mqm/log/ && rm -r /home/ap/mqm/log.bck/
