How to perform a health check in ONTAP 9

Applies to

• ONTAP 9
• AFF & FAS Systems

Description

• This article describes the procedure to conduct a basic system health check for the following scenarios:
  • ONTAP upgrades or Firmware upgrades
  • Hardware replacements
  • Maintenance activities
  • Power related events
•  To conduct a complete system health check follow How to perform a cluster health check with a script in ONTAP

Procedure

1. Confirm each node in the cluster shows true for both Health and Eligibility:
   ::> cluster show
2. Confirm the System Storage Configuration shows expected MPHA state (multi-path, quad-path, single-path):
   ::> system controller config show -slot "-" -device System
3. Confirm the SP/BMC is online:
   ::> system service-processor show -fields status
4. Confirm each aggregate is online:
   ::> storage aggregate show -fields state
5. Confirm all volumes are online:
   ::> volume show -fields state
6. Confirm the state of each network port is as expected:
   ::> network port show
7. Confirm all LIFs are home and operational:
   ::> network interface show -fields is-home,status-oper
8. Confirm there are no system faults present:
   ::> system health alert show
9. Confirm no storage faults are present:
   ::> system health subsystem show
10. Confirm all EMERGENCY/ALERT/ERROR/INFO events in past 24 hours.
    ::> event log show -severity <=NOTICE -time >24h
11. Confirm that any CIFS shares that should be connected are so:
    ::> vserver cifs show
::> vserver cifs session show
::> vserver cifs connection show
12. Verify that the cluster version is the target ONTAP release:
    ::> version
13. Confirm that each node in the cluster shows true for takeover possible:
    ::> storage failover show -fields possible
