Download GISO image to the router using one of the following options:

• PXE boot: when the router is booted, the boot mode is identified. After detecting PXE as boot mode, all available ethernet interfaces are brought up, and DHClient is run on each interface. DHClient script parses HTTP or TFTP protocol, and GISO is downloaded to the box.
• USB boot or Disk Boot: when the USB mode is detected during boot, and GISO is identified, the additional RPMs and XR configuration files are extracted and installed.
• System Upgrade when the system is upgraded, GISO can be installed using install add , install activate , or using install replace commands.

  Important

  To replace the current version and packages on the router with the version from GISO, note the change in command and format. In versions prior to Cisco IOS XR Release 6.3.3, 6.4.x and 6.5.1, use the install update command: install update source <source path> <Golden-ISO-name> replace In Cisco IOS XR Release 6.5.2 and later, use the install replace command. install replace <absolute-path-of-Golden-ISO>

  Note

  To create a Bootable External USB Disk, do the following: Ensure that the USB Boot Disk has a minimum storage of 8GB, and that you have root/admin or appropriate permission to create bootable disk on linux machine. Copy and execute usb-install script on the Linux machine to create a bootable external USB. Router#admin sysadmin-vm:0_RSP0# run chvrf 0 ssh rp0_admin [sysadmin-vm:0_RSP0:~]$ ssh my_host [host:~]$ cd /misc/disk1/ [host:~]$ ./usb-install-712-or-latest.sh asr9k-goldenk9-x64-7.0.2-dr.isso /dev/sdc EFI Preparing USB stick for EFI parted gpt: Failed to create partition - continuing ...

Reset the RSP/RP and plug in bootable USB to RSP/RP's front panel. The USB will get detected in ROMMON. Note that when the system is in ROMMON, and if you add a front panel external USB, the USB will not be detected until the RSP/RP is reset.

  The options to upgrade the system are as follows:

  • system upgrade from a non-GISO (image that does not support GISO) to GISO image: If a system is running a version1 with an image that does not support GISO, the system cannot be upgraded directly to version2 of an image that supports GISO. Instead, the version1 must be upgraded to version2 mini ISO, and then to version2 GISO.

  • system upgrade in a release from version1 GISO to version2 GISO: If both the GISO images have the same base version but different labels, install add and install activate commands does not support same version of two images. Instead, using install update command installs only the delta RPMs. System reload is based on restart type of the delta RPMs.

  • system upgrade across releases from version1 GISO to version2 GISO: Both the GISO images have different base versions. Use install add and install activate commands, or install replace command to perform the system upgrade. The router reloads after the upgrade with the version2 GISO image.

Run the show install repository all command in System Admin mode to view the RPMs and base ISO for host, system admin and XR.
