Reference Guide

NOTE: Nutanix LCM is the prescribed method to update the appliance. If lower than the minimum version (see table 6),
the prescribed update method is to manually uninstall PTAgent and Dell iSM. A reboot may be required after the removal of
Dell iSM. Following the reboot, re-inventory using LCM and install versions of PTAgent and Dell iSM using the LCM install
method.
If iDRAC version is below the minimum supported version that is listed in Table 3 and Table 4, LCM currently performs
step-up update of iDRAC firmware to the minimum version listed in the table before updating iDRAC to latest firmware.
Check NCC Health and Foundation Services
About this task
The steps that are outlined in this section are a suggested outline of how to update an XC Series cluster effectively using LCM.
From one CVM, run the following commands:
Steps
1. NCC Health checks, which is a Nutanix Cluster Health Check. Run it to resolve failure errors and warnings.
Example of the command:
$ncc health_checks run_all
2. Check that the Foundation Service is not running on the CVMs. From any CVM, run:
$allssh "genesis status | grep foundation"
Foundation should not be running, but if it is, the output looks like:
================== 10.xx.xx.xxx
=================
foundation: [ ]
================== 10.xx.xx.xxx
=================
foundation: [ ]
================== 10.xx.xx.xxx
=================
foundation: [ ]
================== 10.xx.xx.xxx
=================
foundation: [ ]
NOTE: If Foundation is running, see the Stopping the Foundation Service section.
Clear job queues
You must clear all job queues in iDRAC from all hosts. This task removes pending and failed jobs and ensures that there are no
pending jobs that could interrupt the LCM process.
About this task
Repeat this step on every node in the cluster. Job queues are found in the iDRAC web console, or alternatively, you can run
from a command prompt that has access to the iDRACs. For more information, contact Dell EMC Support.
To clear all job queues:
