===== Lister les infos d'une zone =====

<code>
zonecfg -z server info
</code>

===== Infos RAM d'une zone =====
<code>
prstat -Z
prstat -z zone -s rss
prstat -z zone -s size
</code>


===== Arrachage de lun impactant la zone locale =====
  * Dans la globale le FS est en IO error :

<code>
unmount -f /data ... (zone local arretée)
</code>

=> vxdisk list indique que l'on est "failed was"

  * Quand la lun est revenu :

<code>
vxreattach
vxvol -g mondg start volX
fsck -F vxfs -o full /dev/vx...
mount /data :error already mounted # => alors que ce n'est pas le cas, workaround:
mv /mount_point /mount_poit.bak ; mkdir /mount_point
mount /data
</code>

  *Démarrage de la zone locale

===== Global zone name from local zone =====

  pkgparam -v SUNWcsr |grep From:| grep -v fern | head -1|awk '{print $9}'

===== Add FS to local zone =====
