适用场景

  • ONTAP 9
  • is-sis  这里的相关参数代表 is-sis-volumeis-sis-logging-enabledis-sis-state-enabled

问题解答

is-sis 只有  启用了volume efficiency 设置的卷的相关参数才会自动设置为true

示例
lccls91001::> set diag

lccls91001::*> volume show -fields is-sis-volume,is-sis-logging-enabled,is-sis-state-enabled
vserver   volume                    is-sis-volume is-sis-logging-enabled is-sis-state-enabled
---------- ------------------------------------------ ------------- ---------------------- --------------------
svm91001  vol1                     true      true           true
svm91001   vol1clone                  true      true           true
svm91001   vol2                     false      false          false
svm91001   vol4                     false      false          false

lccls91001::*> volume efficiency show
Vserver   Volume       State    Status    Progress       Policy
---------- ---------------- --------- ----------- ------------------ ----------
svm91001  vol1        Enabled  Idle     Idle for 10:36:16  -

备注:     

  • is-sis-volume 如果卷启用了克隆或重复数据删除、或者卷上发生了快照还原、则可以是true
  • is-sis-logging-enabled 只有在该卷上启用了重复数据删除时、才为true
    • 在已取消优先级的卷上,is-sis-logging-enabled  为false ,但is-sis-volumeis-sis-state-enabled   仍可保留true
    • 用户可以 在高级权限级别使用volume efficiency promote 命令提升已取消优先级的卷以重新加入自动后台重复数据删除。
