HyperFlex Tips & Commands

Storage Controller VM Commands

•    Sometimes the storage VMs will not start up correctly after a shutdown. The storage VMs might need to be rebooted/services started if you are having issues.
•    #service_status.sh
    o    This command will give you a status of the services running on the storage controller VM.
•    #stmgr restart
    o    This will restart the storage manager service on the controller VM. Sometimes this will stop and you will get errors in the Cisco HyperFlex Connect webpage.
•    #stcli cluster start
    o    This will start up the cluster between the nodes/servers. Sometimes the cluster is offline or not started and executing this command will bring the system back up online.
•    #stcli cluster info
    o    This command you can obtain an overall view of the cluster state. You can see replication factor, whether the cluster is online or offline, and also if the cluster is healthy.
•    #stcli cluster storage-summary
    o    This will give you the status of the storage cluster itself.
•    #stcli cluster storage-summary --detail
    o    This will give you further detail into the cluster health/status of the storage.

ESXi (Node) Commands

•    []vim-cmd vmsvc/getallvms
    o    This will show you the VMs currently running on the node/server.
