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. (ncn-mw#) Ensure that the Redfish endpoint of the removed node’s BMC has been disabled.

    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. (ncn-mw#) Ensure that the nodes have been disabled.

    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.
