3. Save changes by pressing F10 and reboot the server.
Work-Around #3:
NOTE: This work-around assumes that the Cisco IMC is online and the IP is known. This script
also uses default IMC credentials of admin/password, so if these have been changed users will
need to modify the $pass field as required.
This solution is for customers who used DHCP to IP the IMC(s). Use XML API to log into one or
more system and set the "all PCIe Slots OptionROM" flag correctly. A sample script has been
provided below:
Step 1: Download IMC PowerTool module from the following page:
IMC PowerTool
Save & Run the following file as a <filename>.ps1 file:
Import-Module CiscoUcsPs
$multiimc = Set-UcsPowerToolConfiguration -SupportMultipleDefaultUcs $true
# The tool will prompt user to enter IP's when run
$imclist = Read-Host "Enter Cisco IMC IP or list of IMC IPs separated by commas"
[array]$imclist = ($imclist.split(",")).trim()
$user = 'admin'
# The default password is on the next line (update as needed)
$pass = ConvertTo-SecureString –String "password" –AsPlainText -Force
$cred = New-Object –TypeName System.Management.Automation.PSCredential
–ArgumentList $user, $pass
$out = Connect-Imc -Credential $cred $imclist
Set-ImcRackUnit -RackUnit 1 -AdminPower soft-shut-down -Force
Get-ImcBiosSettings | Get-ImcBiosVfPCIOptionROMs | Set-ImcBiosVfPCIOptionROMs -
VpPCIOptionROMs "Enabled" -Force
sleep 25
Set-ImcRackUnit -RackUnit 1 -AdminPower up -Force
$out = Disconnect-Imc
Work-Around #4 (Live Linux USB with UCScfg):
This work-around involves creating a live bootable USB, that includes the tools necessary to
correct the OptionROM settings. This requires a blank USB that is at least 4GB in size. Note: the
