I have an old cluster of 4 NX-8035 nodes running AHV used for testing purposes. The LCM update is failing with sata_dom_wearout_check. Is there anyway to skip that check when running LCM updates? This is old hardware and I wont be replacing any parts, just want to get updates to run.
*Warning
This is a temporary solution.
The methods below can crash your cluster.
Please only use it on testbeds.
1. Backup “/home/nutanix/ncc/plugin_config/plugin_schema/health_checks/disk_checks.json”
cd ~/ncc//plugin_config/plugin_schema/health_checks
cp disk_checks.json disk_checks.json.orig
2. vi disk_checks.json and Delete “plugin_schema_list” includes “name: sata_dom_wearout_check”
from “plugin_schema_list {“
plugin_schema_list {
name: "sata_dom_wearout_check"
executable_name: "health_checks hardware_checks disk_checks sata_dom_wearout_check"
check_schema_list {
...
check_metadata {
ncc_version: "Unknown"
source_jira_ticket: "TBD"
fix_jira_ticket: "NA"
component: kPlatformSolutions
hw_specific: False
hypervisor_specific: False
comment_list: "NA"
}
}
} # til “}”
3. copy disk_checks.json to other cvm
scp disk_checks.json <CVMIP2>:~/ncc/plugin_config/plugin_schema/health_checks
scp disk_checks json <CVMIP3>:~/ncc/plugin_config/plugin_schema/health_checks
4. LCM Upgrade job
5. After upgrade, rollback to backup file.
cp disk_checks.json.orig disk_checks.json
scp disk_checks.json <CVMIP2>:~/ncc/plugin_config/plugin_schema/health_checks
scp disk_checks json <CVMIP3>:~/ncc/plugin_config/plugin_schema/health_checks
Done.
