configuration cluster show

Below is sample output of above command. In below sample command the ZFS Storage heads are configured in owner/stripped cluster configuration.

Properties:state = AKCS_OWNER
description = Active (takeover completed)
peer_asn = ZZZZZ-ZZZZ-ZZZZ
peer_hostname = storagehead2
peer_state = AKCS_STRIPPED
peer_description = Ready (waiting for failback)

2. Check if there are any active problems using below command. There should be no faults in healthy ZFS heads.

maintenance problems show

3. Check if the ZFS head has pool active or in exported status using below command. Pool should not be in degraded or failed state.

configuration storage show

pool = <poolname>                       
status = online                       
errors = 0                       
owner = storagehead1                     
profile = mirror                 
log_profile = log_stripe               
cache_profile = cache_stripe

4. Check the network interfaces status of head using below command. Network interfaces should be UP.

configuration net interfaces ls

Below is sample output of above command.

INTERFACE   STATE    CLASS LINKS       ADDRS                  LABEL
ixgbe0      up       ip    ixgbe0      10.141.135.84/23       ixgbe0

5. Check the status of Infiniband IB Ports on ZFS Storage Appliance using below command. Both the IB Ports should be UP and Active.

confirm shell ibstat

6. Check if there are any Hardware problems using below command. There should be no hardware problems in a a healthy system.
