Stand-Alone Upgrade; Check /Boot For Free Space; Upload The Stage 3 Boot Loader And System Image - Oracle Netra Server X5-2 Installation Manual

Stand-alone Upgrade

This process incurs system downtime; your Oracle Communications Session Border
Controller stops passing traffic for a period of time. Please plan for your standalone upgrade
accordingly.

Check /boot for free space

•
On the OCSBC, check for adequate space in the /boot volume to upload the new boot
image and bootloader. Use the show space boot command.
OCSBC# show space boot
boot: 24759488/25760512 bytes (99%) remaining
You may delete files from an SFTP client if you need to free space.
The command check-space-remaining boot performs the same function as show
space boot.

Upload the Stage 3 Boot Loader and System Image

Whenever you upgrade the software image, upload the stage 3 boot loader and the new
system image file to the system. The stage 3 boot loader is backward compatible with
application software.
The Stage3 boot loader is generally backward compatible with previous releases, but Oracle
recommends that the Stage3 boot loader be installed from the same Major.Minor version as
the system image. It is not normally necessary to update the boot loader when installing a
maintenance or patch release when the Major.Minor release is the same.
System upgrades typically consist of transferring the new system image and stage3 boot
loader to the system and setting boot parameters to the new system software. To ensure
compatibility, copy the stage 3 boot loader to /boot/bootloader before you update the
boot parameters to use the new software image file. The boot loader file must be renamed
to /boot/bootloader on the target system with no file extension. When upgrading an HA
pair, you must perform the upgrade procedure on each HA node.
Follow the steps below to upload the Stage3 boot loader and system image.
Obtain the stage 3 boot loader image file (*.boot).
1.
Upload the stage 3 boot loader image file (*.boot) as /boot/bootloader to your
2.
system using an SSH File Transfer Protocol (SFTP) client.
Upload the new system software image (*.bz) to /boot/.
3.
Validate the bootloader by rebooting the Oracle Communications Session Border
4.
