PowerScale：如何檢查叢集健全狀況和未解決的事件

1. 在叢集的任何節點上開啟 SSH 連線，然後使用「root」帳戶登入。
2. 執行下列命令

# isi status

Cluster Name: Test
Cluster Health:     [  OK ]
Storage Efficiency: 0.83 : 1
Cluster Storage:  HDD                 SSD Storage
Size:             344.4G (469.8G Raw) 0 (0 Raw)
VHS Size:         125.4G
Used:             18.5G (5%)          0 (n/a)
Avail:            325.9G (95%)        0 (n/a)

                   Health  Throughput (bps)  HDD Storage      SSD Storage
ID |IP Address     |DASR |  In   Out  Total| Used / Size     |Used / Size
---+---------------+-----+-----+-----+-----+-----------------+-----------------
  1|10.xxx.x.xx    | OK  |    0| 132k| 132k| 3.3G/57.4G(  6%)|(No Storage SSDs)
  2|10.xxx.x.xx    | OK  |    0| 714k| 714k| 3.3G/57.4G(  6%)|(No Storage SSDs)
  3|10.xxx.x.xx    | OK  |    0|    0|    0| 2.6G/57.4G(  5%)|(No Storage SSDs)

---+---------------+-----+-----+-----+-----+-----------------+-----------------
Cluster Totals:          |    0| 1.9M| 1.9M|18.5G/ 344G(  5%)|(No Storage SSDs)

     Health Fields: D = Down, A = Attention, S = Smartfailed, R = Read-Only

Critical Events:
Time            LNN  Event
--------------- ---- -------------------------------------------------------

從上述輸出結果中，我們看到叢集執行狀況：[OK] 表示良好，也沒有未完成的嚴重事件。 

若要檢查整個叢集上是否有任何未解決的警示，您可以執行下列命令。 

# isi event groups list --resolved=false
ID   Started     Ended  Causes Short         Lnn  Events  Severity
---------------------------------------------------------------------
3072 12/17 00:55 --     QUOTA_INTERNAL_ERROR 1    9       warning
4105 12/20 01:11 --     QUOTA_NOTIFY_FAILED  3    6       information
---------------------------------------------------------------------

清除特定事件。 

# isi event groups modify --resolved=yes --ignore=yes --id=<Group ID from above command >

Eg : isi event groups modify --resolved=yes --ignore=yes --id=3072

清除整個叢集上的舊警示。 

For OneFS 7.x.x.x and Above

# isi events cancel all
# isi events quiet all

For OneFS 8.x.x.x and above

# isi event bulk --ignore=true
# isi event bulk --resolved=true
