a. At the EFI Shell prompt, type acpiconfig default and press Enter.

b. Type reset and press Enter.

6. System is unbootable after adding new disks.

When you add new disks, the system may fail with one of the following messages:

init=

VFS root not found

To fix the problem:

a. Remove any disks you've added since you last booted your system.

b. Invoke parted /dev/sdX where sdX is the disk where your root partition resides.

c. Use name command to assign forward slash (/) as a LABEL to the root file system. The

help name from inside parted explains the syntax you should use, for example, name

1 /

d. Manually verify root= "LABEL= /" is in each image section of the

/boot/efi/SuSE/elilo.conf file.

default=linux

e. Manually verify LABEL"=/" entry is in the /etc/fstab.

7. If you want rx7620 or rx8620 server hardware to power off when the shutdown -h comand

or poweroff command is issued, run the acpiconfig enable softpowerdown

command from the EFI shell and reset the nPartition to make the ACPI configuration take

effect.

The normal behavior on rx7620 and rx8620 servers is for an nPartition to be made inactive

(all cells are in a boot-is-blocked state) when shutdown -h or poweroff is issued from

the SLES command line. This behavior is established with the acpiconfig disable

powerdown setting, which is the normal setting for the single-pci-domain ACPI configuration.

On HP Integrity Superdome servers, an nPartition is always made inactive when halted

from the operating system (for example, after shutdown -h), and this behavior cannot be

changed.
