Ask BOS to describe the component. The session that last acted upon the node is listed in this description.
(ncn-mw#) Set an environment variable to the xname of the node in question.
For example:
export NODE_XNAME="x3000c0s17b0n0"
(ncn-mw#) Query the BOS component for that node.
BOS_SESSION_ID=$(cray bos v2 components describe $NODE_XNAME --format json | jq -r .session)
echo $BOS_SESSION_ID
The output will be the BOS session ID. For example:
94e712ab-df76-40ee-8cfb-7ac487fd8a13
(ncn-mw#) Describe the BOS session.
cray bos v2 sessions describe $BOS_SESSION_ID --format json
This will output information about the BOS session. For example:
{
"components": "x3000c0s17b0n0",
"limit": "x3000c0s17b0n0",
"name": "94e712ab-df76-40ee-8cfb-7ac487fd8a13",
"operation": "reboot",
"stage": false,
"status": {
"end_time": "2023-06-27T00:55:58",
"error": null,
"start_time": "2023-06-27T00:33:17",
"status": "complete"
},
"template_name": "gdr-tmpl"
}
The template_name parameter is the name of the BOS session template used to boot or reboot the node.
