Recently, we upgraded firmware on all our blade enclosures and servers. This time we got stuck with the Citrix servers. We were informed that the Citrix applications are not working after the recent updates. After lot of struggle it was traced out that the issue was due to the ROM version incompatibility and we had to restore the previous ROM version.
This was achieved using the “Redundant ROM Settings” available under RBSU (ROM Based Setup Utility). Please follow the below steps to restore your previous ROM without searching for the setup files.
1. Access ROM Based Setup Utility by pressing the F9 key during power on.
2. Select “Advanced Options”.
3. Select “Advanced System ROM Options”.
4. Choose “ROM Selection”.
5 Select “Switch to Backup ROM”.
6. Press the Enter key.
7. Press the Esc key to exit the current menu or press the F10 key to exit RBSU. The server restarts automatically.
