PowerScale: How to check the cluster health and unresolved events

1. Open an SSH connection on any node in the cluster and log in using the "root" account.
2. Run the following command

# 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
--------------- ---- -------------------------------------------------------

From the above output we see that the Cluster Health: [OK] is good and there are no outstanding Critical Events as well. 

To check for any outstanding alerts on the entire cluster, you can run the below command. 

# 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
---------------------------------------------------------------------

To clear a particular event. 

# 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

To clear all the old alerts on the entire cluster. 

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
