Where does ucs save firmware update files?

menash

Level 1

i have a ucs blade server running firmware 4.13b and ive been trying to figure out a solution for offline upgrades. if i use scope cimc/firmware update (ftp) i know the update is being done and is not applied until i issue "activate", but i've been trying to figure out where are the firmware files im downloading go to, so i can do a few checks on devices that fail updating. searched everywhere on the server itself (kvm) and i cant seem to find anything on cimc chip internal storage or anything like that.

is there a way to upload a firmware bin file onto the server and then call it using cimc cli for upgrades?

Yes, you can upload a firmware bin file onto the server and then call it using CIMC CLI for upgrades. To do this, you can follow these steps:

1. First, you need to download the desired firmware bin file from Cisco's website. You can find the firmware files here: https://software.cisco.com/download/home/283850974/type/283853158/release/

2. Next, you'll need to set up an HTTP, HTTPS, FTP, or TFTP server to host the firmware file. If you don't have one, you can use a free tool like Tftpd64 or FileZilla Server.

3. Place the firmware bin file in the appropriate directory on the server.

4. Log in to the CIMC CLI of the UCS blade server.

5. Enter the following command to start the firmware update process:

```
scope firmware
```

6. To specify the firmware source, enter the following command:

```
update [http/https/ftp/tftp]://[server_address]/[path_to_firmware_file] username [username] password [password]
```

Replace `[http/https/ftp/tftp]` with the protocol of your server, `[server_address]` with the IP address or hostname of your server, `[path_to_firmware_file]` with the path to the firmware bin file on your server, `[username]` and `[password]` with the credentials for your server (if required).

For example:

```
update ftp://192.168.1.100/ucs-b-series-blades-firmware-4.13b.bin username cisco password cisco123
```

7. After the firmware file is downloaded, you can activate it by entering the following command:

```
activate
```

8. The server will then prompt you to confirm the activation. Type `yes` to proceed.

9. The UCS blade server will now reboot and apply the firmware update.

Remember that the firmware files are not stored on the server itself but are downloaded directly from the source you specified during the update process. By following this process, you can easily update the firmware of your UCS blade server using the CIMC CLI.

The firmware for blades that comes from the B series bundle is all staged in the /bootflash folder on the FIs.

The components like BIOS and CIMC each have dual 'slots' in internal flash that accommodate 2 versions (i.e. current/running, and backup).  The 'scratch'/temp areas you are looking for are not end user visible.
