Configure a System Boot Loader Password

You can configure the storage servers to require a system boot loader password whenever an administrator attempts to access the boot loader (GRUB) editor or command interface.

1. Log into the storage server as celladmin.

   See Log into the Storage Server OS.

2. Configure a system boot loader password.

   # /opt/oracle.cellos/host_access_control grub-password
   New GRUB password: password
   Retype new GRUB password: password
   [...]
   

3. Verify the setting.

   If the command returns a value similar to this example, then a boot loader password is installed.

   # grep "^password" /etc/grub.conf
   password --md5 $1$Hdner/$Q2VoiZeTJwmNQsFnH9oFy.
