Cisco UCS box already included CIMC, the we can write some script to change boot order by CIMC automatically. it is useful for PXE installation.

#!/usr/bin/expect

if {$argc<4} {

        puts stderr "Usage: $argv0 ip login passwaord option(pxe/hdd)"
        exit 1
}

set timeout 600

set IP        [lindex $argv 0]
set LOGIN    [lindex $argv 1]
set PASSWORD    [lindex $argv 2]
set OPTION [lindex $argv 3]

set flag 1
spawn ssh -t -p 22 $IP -l $LOGIN
while {$flag > 0} {
    expect {
        "\(yes\/no\)\?" { send "yes\r" }
                "assword:" { send "$PASSWORD\r"; set flag 0}
        timeout exit
    }
}

expect "#" { send "scope bios\r" }
if { $OPTION == "pxe"} {
    expect "#" { send "set boot-order pxe,hdd,cdrom,fdd,efi\r" }
} else {    
    expect "#" { send "set boot-order hdd,pxe,cdrom,fdd,efi\r" }
}
expect "#" { send "commit\r" }
expect "#" { send "top\r" }
expect "#" { send "scope chassis\r" }
