Appendix A Turbo Boot Procedure
Step 2 Configure the ROMMON variables on the standby RP and reset
This will bring the standby RP in a booting loop. If you turboboot a MC this has to be done on all
nonDSC RPs. The RP(s) will remain in the booting loop (mbi hunt) until they receive a MBI
confirmation with the remote image to boot from the active RP of the DSC. The MBI confirmation will
be received once the active RP on the DSC has booted the mini image. Refer to the next step.
Step 3 Configure the rommon variables on the active RP and boot the vm image.
Instead of a tftp server disk1 can be specified as well. But this will take significant longer
Warning Do NOT use the option "format"if you migrate to a flash disk formatted with the FAT32 file system or if
you have a flash disk formatted with FAT32.
In this case configure the TURBOBOOT variable as follows:
The installation is complete when all nodes on the system are in state "IOS XR RUN" and the standby
RP is "NSR-ready".
