Symptoms

After successful login to the ILOM, starting the console hangs:

# ssh root@xx.xx.xx.xx

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y
Serial console started. To stop, type ESC (

Initial troubleshooting reveals the following.

Reboot of the SP has no effect on the problem.
From the ILOM BUI -> Remote Control -> Redirection -> Launch Remote Console allows you to to login.
You can ssh to the appliance itself. It is only console access which hangs.

Changes

Cause

The menu.lst file is missing an entry for "console". If the kernel$ line does not direct the console to ttya, console login will hang.

Solution

The problem is solved by defining console in the menu.lst file. This hidden file can be updated by root in the appliance shell.

Please contact Oracle Support to assist in making these changes to your appliance.

               "Warning : The following command(s)/instruction(s) may result in changes to appliance settings/configuration, and could
                          therefore result in serious damage if not fully understood and implemented correctly. These steps must be
                          carried out only by a highly experienced Oracle TSC or Field Support engineer, trained to work at the Solaris
                          Shell on the ZFS Storage Appliance. If you are at all unsure whether to proceed, please stop and consult your
                          manager or supervisor immediately.".

1. # mount -F zfs system /mnt
2. # cd /mnt/boot/grub

3. Add console definition to the kernel$ line as shown (two microcode releases need editing)
