Downloading the 6.2.0 image using the relative path

1.
Log in to the switch as admin.
2.
Enter the firmwareDownload command with the -U operand:
admin>firmwaredownload –U v6.2.0

Downloading the 6.2.0 image using the absolute path

1.
Log in to the switch as admin.
2.
Enter the firmwareDownload command with the -U operand:
admin>firmwaredownload –U /usb/usbstorage/brocade/firmware/v6.2.0

FIPS Support

Federal information processing standards (FIPS) specify the security standards needed to satisfy a
cryptographic module utilized within a security system for protecting sensitive information in the computer
and telecommunication systems. For more information about FIPS, see Chapter 4,
security
features" on page 1 17.
The 6.2.0 firmware is digitally signed using the OpenSSL utility to provide FIPS support.To use the digitally
signed software, you must configure the switch to enable Signed Firmwaredownload. If it is not enabled,
the firmware download process ignores the firmware signature and work as before.
If Signed Firmwaredownload is enabled, and if the validation succeeds, the firmware download process
proceeds normally. If the firmware is not signed or if the signature validation fails, firmwareDownload
fails.
To enable or disable FIPS, see Chapter 4,

Public and Private Key Management

For signed firmware, HP StorageWorks B-Series products use RSA with 1024-bit length key pairs, a private
key and a public key. The private key is used to sign the firmware files when the firmware is generated. The
public key is packaged in an RPM-package as part of the firmware, and is downloaded to the switch. After
it is downloaded, it can be used to validate the firmware to be downloaded next time when you run
firmwaredownload.
The public key file on the switch contains only one public key. It is able to validate only firmware signed
using one corresponding private key. If the private key changes in future releases, you need to change the
public key on the switch by one of the following methods:
• By using the firmwareDownload command. When a new firmware is downloaded,
firmwareDownload always replaces the public key file on the switch with what is in the new
firmware. This allows you to have planned firmware key changes.
• By using the firmwareKey command. This command retrieves a specified public key file from a
specific server location and replaces the one on the switch. So for easy access, the information
regarding firmware versions and their corresponding public key files should be documented in the
release notes or stored in a known location in the HP website http://www.hp.com. This command
allows the customer to handle unplanned firmware key changes.
However, if the public key file has been modified using the firmwarekey command,
firmwareDownload will not replace this file in the subsequent downloads because it thinks the
change is intentional. You must use the firmwarekey command for subsequent updates of this file.
