8.7.2 Upgrading RoCE Network Fabric Switch Firmware Software

Upgrade the RoCE Network Fabric switches using the patchmgr command.

Before starting this task, review the notes in Upgrading and Downgrading RoCE Network Fabric Switch Firmware, and complete the steps in Preparing for RoCE Network Fabric Switch Firmware Upgrades or Downgrades.

1. On the server where you downloaded the patch, use the patchmgr command to upgrade the switches.

   # ./patchmgr --roceswitches switches.lst --upgrade [--force]
     [-log_dir {absolute_path_to_log_directory | AUTO}]

   In the patchmgr command:

   • --force optionally proceeds with the operation even if the switch is already on the target firmware version or the RoCE Network Fabric is experiencing non-critical failures.

   • -log_dir specifies the absolute path to the log directory, or AUTO instructs patchmgr to automatically create the log directory. This option is required when running patchmgr as a non-root user.

   Note:

   Prior to Oracle Exadata System Software release 19.3.9, you must run patchmgr as a non-root user for patching RoCE Network Fabric switches.
2. Verify the upgrade.

   Use the show version command to verify the firmware version on the switch:

   For example:
