Check the disk volume size required by the BIG-IQ software upgrade

Before you check the required disk volume size:
  • Upload the BIG-IQ software to the BIG-IQ you are upgrading.
  • Confirm that the
    imageplan
    script is on the BIG-IQ you plan to upgrade.This script is located in the
    /usr/bin
    folder. Because this folder is already in your path definition, you can initiate this script directly.
The
var
partition must be at least 2.5 times larger than it needed to be for earlier BIG-IQ version. When you upgrade BIG-IQ, you can use the size requirements from the software image you plan to install so you can be confident that your disk volume sizes are sufficient before you upgrade your BIG-IQ.
  1. From the command line, use SSH to log in (as
    root
    ) to the BIG-IQ you are going to upgrade.
  2. Copy the software image to the
    /shared/images
    folder on the BIG-IQ you plan to upgrade by typing the following command:
    #
    cp <big-iq-software-image>.iso /shared/images/<big-iq-software-image>.iso
  3. Run the
    imageplan
    script on the software image to determine the file system sizes required by typing the following command.
    #
    ./imageplan /shared/images/<big-iq-software-image>.iso
    product BIG-IQ version X.X.X build x.x.xxx (BIGIQ<version>) selected
    BIG-IQ returns output reflecting the sizing requirements for this upgrade.
Now you know the size requirements for the image you plan to install.
