How To Shutdown Netapp Cluster Gracefully

Shutdown Netapp Cluster Gracefully 

1. Go to Advanced mode and run configuration Backup
2. Identify Primary and Secondary Nodes
3. Stop Vservers
4. Disable Failover Or HA
5. Initiate Node shutdown one by one

ARK-NA::> set advanced

##### Repeat for All nodes ####
 ARK-NA::> system configuration backup create -node ARK-NA01 -backup-type cluster -backup-name BACKUP_BEFORE_SHUTDOWN_NODE1 


ARK-NA::*> system configuration backup show
Node       Backup Name                               Time               Size
---------  -----------------------------------------
ARK-NA01   ARK-NA.8hour.2018-10-25.10_15_00.7z       10/25 10:15:00     81.52MB
ARK-NA01   ARK-NA.8hour.2018-10-25.18_15_00.7z       10/25 18:15:00     86.11MB
ARK-NA01   ARK-NA.8hour.2018-10-26.02_15_00.7z       10/26 02:15:00     86.85MB

Check Primary and Secondary node details and shutdown secondary nodes first

ARK-NA::> cluster ring show

Repeat All the Vservers

ARK-NA::> vserver stop -vserver VSERVER-NAME 

Disable Failover after first start

ARK-NA::> storage failover modify -node * enabled false

Login to each node and run this command

ARK-NA::> halt -node ARK-NA01 -inhibit-takeover true -ignore-quorum-warnings true -reason "Maintainance Activity Planned"

Or

ARK-NA::> system node halt -node ARK-NA01 -inhibit-takeover true -skip-lif-migration-before-shutdown true -reason Shutdown

Data ONTAP API Failed :Loop detected in next() for table compliance_status.

I see an error when adding licenses to Netapp Cluster mode simulator as mentioned below.

"Data ONTAP API Failed :Loop detected in next() for table compliance_status. Next on "NFS 1-81-0000000000000004082368511" returned "NFS 1-81-0000000000000004082368511". (Error: 13001)"

To resolve above issue you have to do below steps on second cluster node.

When you see an VLOADER> prompt type below command

VLOADER> setenv SYS_SERIAL_NUM 4032368-50-8
VLOADER> setenv bootarg.nvram.sysid 4032368508

Verify that the information was saved correctly or not

VLOADER> printenv SYS_SERIAL_NUM
VLOADER> printenv bootarg.nvram.sysid
VLOADER> boot

clean configuration and re-configure the second node.

That's it. Enjoy practicing Netapp Storage Lab.
