Verify Node Removal

Use this procedure to verify that a node has been successfully removed from the system.

Prerequisites

  • The Cray command line interface (CLI) tool is initialized and configured on the system. See Configure the Cray CLI.
  • This procedure requires the component name (xname) of the removed node to be known.

Procedure

  1. Ensure that the Redfish endpoint of the removed node’s BMC has been disabled.

    ncn-m001# cray hsm inventory redfishEndpoints describe x3000c0s19b4 --format toml
    

    In the following example output, the Enabled field is false, indicating that the Redfish endpoint has been disabled.

    Domain = ""
    MACAddr = "a4bf012b71a9"
    UUID = "61b3843b-9d33-4986-ba03-1b8acd0bfd9c"
    IPAddress = "10.254.2.13"
    RediscoverOnUpdate = true
    Hostname = "10.254.2.13"
    Enabled = false
    FQDN = "10.254.2.13"
    User = "root"
    Password = ""
    Type = "NodeBMC"
    ID = "x3000c0s19b4"
    
    [DiscoveryInfo]
    LastDiscoveryAttempt = "2020-04-03T12:37:48.833692Z"
    RedfishVersion = "1.1.0"
    LastDiscoveryStatus = "DiscoverOK"
    
  2. Ensure that the nodes have been disabled.

    ncn-m001# cray hsm state components describe x3000c0s19b4n0 --format toml
    

    In the following example output, the Enabled field is false, indicating that the node has been disabled.

    ID = "x3000c0s19b4n0"
    Type = "Node"
    State = "Off"
    Flag = "OK"
    Enabled = false
    Role = "Compute"
    NID = 1164
    NetType = "Sling"
    Arch = "X86"
    Class = "River"
    
  3. If a River node will not be replaced, update SLS to omit it.
