Solaris grub

Set SP-console on x86-systems to 115200 Baud

You need to set the new speed in all three places:

1. grub
2. SP host serial
3. BIOS serial

Solaris 11

Set speed and port in grub

# bootadm set-menu console=serial serial_params=0,115200,8,N,1
# bootadm generate-menu -f
# eeprom console=ttya
# eeprom ttya-mode=115200,8,n,1,-

Solaris 10

Set speed and port in grub

/rpool/boot/grub/menu.lst

title Oracle Solaris 10 X86
findroot (pool_rpool,0,a)
kernel$ /platform/i86pc/multiboot -B $ZFS-BOOTFS,console=ttya,ttya-mode="115200,8,n,1,-"
module /platform/i86pc/boot_archive

title Solaris failsafe
findroot (pool_rpool,0,a)
kernel /boot/multiboot -s -B console=ttya,ttya-mode="115200,8,n,1,-"
module /boot/amd64/x86.miniroot-safe

Set speed

/boot/solaris/bootenv.rc

setprop ttya-mode '115200,8,n,1,-'

Active after reboot.

Set console login speed

/etc/ttydefs

console115200:115200 hupcl opost onlcr:115200::console

# svccfg -s svc:/system/console-login setprop ttymon/label= astring: "console115200"
# svcadm refresh svc:/system/console-login
# svcadm restart svc:/system/console-login

Set speed in BIOS

Enter BIOS setup with F2 or CTRL+E, then go to

Advanced -> Serial Port Console Redirection -> Bits per second : 115200

Set speed for SP host serial

-> set SP/serial/host pendingspeed=115200 commitpending=true
Set 'pendingspeed' to '115200'
Set 'commitpending' to 'true'

-> show SP/serial/host speed

  /SP/serial/host
    Properties:
        speed = 115200

The problem:

GRUB loading...

Get into the normal grub

Find your devices:

grub rescue> ls
(hd0) (hd0,gpt9) (hd0,gpt2) (hd0,gpt1) (hd1)

Find the directory where the normal.mod file resides

In this example the boot environment is named Solaris11.3SRU1. Remember to replace Solaris11.3SRU15 with your boot environment name.

grub rescue> ls (hd0,gpt2)/ROOT/Solaris11.3SRU15/@/boot/grub/i386-pc
... normal.mod ...

Set the prefix to the right place

Remember to replace Solaris11.3SRU15 with your boot environment name.

grub rescue> set
prefix=(hd0,gpt2)//@/boot/grub/i386-pc
root=hd0,gpt2
grub rescue> set prefix=(hd0,gpt2)/ROOT/Solaris11.3SRU15/@/boot/grub/i386-pc

Now you can load and start the module called "normal"

grub rescue> insmod normal
grub rescue> normal
                  GNU GRUB  version 1.99,5.11.0.175.2.0.0.42.2

   Minimal BASH-like line editing is supported. For the first word, TAB
   lists possible command completions. Anywhere else TAB lists possible
   device or file completions.

grub>

Normal grub is bootet, now start the Solaris

At the grub> prompt enter the following lines. Remember to replace Solaris11.3SRU15 with your boot environment name.

insmod zfs
zfs-bootfs /ROOT/Solaris11.3SRU15/@/ zfs_bootfs
set kern=/platform/i86pc/kernel/amd64/unix
$multiboot /ROOT/Solaris11.3SRU15/@/$kern $kern -B $zfs_bootfs
insmod gzio
$module /ROOT/Solaris11.3SRU15/@/platform/i86pc/amd64/boot_archive
boot
