XCO Command Blocking during Firmware Download

Before starting the firmware download, XCO verifies that all system services are not currently busy. If the verification does not complete within 2 minutes and 30 seconds, XCO displays an error. Retry the firmware download later.

Inventory Command Blocking

The following inventory commands are blocked when a firmware download is in progress for a specific device:

Network Essentials (Native CLIs)
Device Execute CLI
Device Delete

Fabric Command Blocking

The following fabric commands are blocked when at least one of the device is in fwdl-in-progress state:
- Fabric device add
  Example: [Supposing firmware download is in progress for 10.20.246.1]
```
efa fabric device add --ip 10.20.246.2 --rack rack1 --name non-clos --username admin --password password

Error:  Device(s) 10.20.246.1 are going through firmware download
```
- Fabric device remove
  Example: [Supposing firmware download is in progress for 10.20.246.1]
```
efa fabric device remove --name non-clos --ip 10.20.246.1,10.20.246.2
         Remove Device(s) [Failed]
         Removal of  device with ip-address =  [Failed]

Reason: Device(s) 10.20.246.1 are going through firmware download
```
- Fabric configure
  Example: [Supposing firmware download is in progress for 10.20.246.1]
```
efa fabric configure --name non-clos

Error:  Device(s) 10.20.246.1 are going through firmware download
```

The following fabric commands are allowed even when the devices are in fwdl-in-progress state:
- Fabric device remove with “no-device-cleanup" flag
- Fabric delete with “force” option
- Fabric topology show physical/underlay/overlay to display the output by excluding the devices in fwdl-in-progress-state

Tenant Command Blocking

If the target device list for a particular tenant operation has at least one device in fwdl-in-progress state, then the entire operation is rejected with an error to the user.
Example: [Supposing firmware download is in progress for 10.24.80.158]
```
efa tenant po create --name po1 --tenant t1 --speed 10Gbps --negotiation active --port 10.24.80.158[0/3], 10.24.80.159[0/3]

PortChannel creation failed:      
      Error: Firmware download is in progress for the devices [10.24.80.158]
```
If the target device list for a particular tenant operation has no device in fwdl-in-progress state, then the operation proceeds as usual.
Example: [Supposing firmware download is in progress for 10.24.80.158]
```
efa tenant po create --name po1 --tenant t1 --speed 10Gbps --negotiation active --port 10.24.80.159[0/3]

PortChannel creation succeeded
```
