Comware 7 MSR Router upgrade with no space

  • 1.  Comware 7 MSR Router upgrade with no space

    Posted May 29, 2021 09:32 AM

    The Problem - insufficient space in router flash

    I has some new firmware to install on an MSR3012 router running Comware 7, but there was not enough free space. The process involves copying the large IPE file containing all the BIN files, but that means having at least three time more space on the flash that the IPE:
    • original BIN files (current firmware)
    • new IPE file
    • space for the extracted BIN files (new firmware)
    As you can see from this view, there is simply not enough space.

    The "brave" solution

    As the snobby waiter said to me in a fancy restaurant after I selected tap water over the other expensive offerings, "that's a brave choice, sir."

    Don't try this on a whim; if things go wrong, it could be a messy exercise getting the router back online, because this process deletes the files used for fallback.

    Process

    1. Delete all the current firmware version BIN files from the flash - they are now running in memory.
    2. Run the upgrade with the new firmware IPE file.
    3. Check for successful completion.
    4. Reboot the router.

    Steps

    Delete the existing BIN files. You may want to FTP them off first, just in case something goes wrong...
    • msr3000-cmw710-boot-r0707p12.bin
    • msr3000-cmw710-data-r0707p12.bin
    • msr3000-cmw710-security-r0707p12.bin
    • msr3000-cmw710-system-r0707p12.bin
    • msr3000-cmw710-voice-r0707p12.bin

    Use the following example:
    <MSR3012>delete /unreserved msr3000-cmw710-system-r0707p12.bin
    The file cannot be restored. Delete cfa0:/msr3000-cmw710-system-r0707p12.bin? [Y/N]:y
    Deleting the file permanently will take a long time. Please wait...
    Deleting file cfa0:/msr3000-cmw710-system-r0707p12.bin... Done.
    ​


    You should also empty the recycle bin in case there are other deleted files taking up space.

    I know that problem. But there is another way I used. The IPE file is nothing then an ZIP file. You can extract it on your computer with a ZIP-Reader and get the *.bin files. Then copy the bin-files to the router and use the boot-loader command to set the new files as main startup image and the old ones as backup startup images. then reboot the switch. with that one you have enough space left and both images on the router for main and backup.

    regards

    "The IPE file is nothing then an ZIP file. You can extract it on your computer with a ZIP-Reader and get the *.bin files."

    Really? AFAIK dearchiving an IPE file is not that easy.

    That could be really useful. I looked into the IPE file with 7Zip and could see files - but not .bin files. Could you post some more details please Manuel?

    Same here (IPE archive's content can't be fully extracted) so I'm curious too.

    The images that have passed all examinations will be used as the main startup software images at the next reboot on slot 1.
    <MSR3012-02>displ boot
    Software images on slot 1:
    Current software images:
    cfa0:/msr3000-cmw710-boot-r0809p33.bin
    cfa0:/msr3000-cmw710-system-r0809p33.bin
    Main startup software images:
    cfa0:/msr3000-cmw710-boot-r0809p33.bin
    cfa0:/msr3000-cmw710-system-r0809p33.bin
    cfa0:/msr3000-cmw710-security-r0809p33.bin
    cfa0:/msr3000-cmw710-data-r0809p33.bin
    Backup startup software images:
    None
    <MSR3012-02>reboot

    After reboot and testing you are good to delete old .bin files. No drama, no risk :-)

    Best, Gorazd
