  • LUNとその基盤となるボリュームはどちらもシンボリュームです。

ASUPのVol-Status-vに従ってボリュームパラメータ を指定:
guarantee=none   
fractional_reserve=0,
try_first=volume_grow
Volume autosize settings: mode=grow_shrink
maximum-size=100 TB, minimum-size=10 TB
grow-threshold-percent=98%, shrink-threshold-percent=50%

ASUPのlun.xmlに基づくLUNパラメータ:

Space reservatiion Disabled

Space alloctaion is disabled

 

  •  影響を受けるボリュームをホストしている基盤となるアグリゲート もフルであり、 ASUPのDF -A LOGに従って100%に達しています。
