list disks by node

[ghost]

Feature request
the command:

sfcli -n <connection> list drive list

should have a '--node <node_id>' option to list all drives belonging to a node.
Use case when removing a node from the cluster, all its drives need to be removed first and listing this way would help.

It's not going to happen soon, it seems, so here are some ideas:

• CLI: store output in JSON file and then do some massaging to extract the fields you want. Example with jq:

$ sfcli -m 192.168.1.34 -u admin -p admin drive list | jq '.drives | .[] | {id: .drive_id, slot: .slot, node: .node_id}' 

Output:

{
  "id": 1,
  "slot": 1,
  "node": 1
}
{
  "id": 2,
  "slot": 2,
  "node": 1
}
{
  "id": 3,
  "slot": 3,
  "node": 1
}
{
  "id": 4,
  "slot": 4,
  "node": 1
}

• Simplify further and use SolidFire Python SDK to get this info easily. You can still call sfcli from Python if the rest of your script is written in SolidFire CLI:

node_list = sfe.list_active_nodes().to_json()['nodes']
drive_list = sfe.list_drives().to_json()['drives']
for node in node_list:
    for drive in drive_list:
        if drive['nodeID'] == node['nodeID']:
            print("Drive", drive['driveID'], "is in chassis slot", drive['chassisSlot'], "of node", node['nodeID'])

Output:

Drive 1 is in chassis slot 1 of node 1
Drive 2 is in chassis slot 2 of node 1
Drive 3 is in chassis slot 3 of node 1
Drive 4 is in chassis slot 4 of node 1
