firmware upgrade broke box?

Fri Sep 25, 2015 9:18 pm

I tried to upgrade on the DC 8-port switch from 1.3.2 -> 1.3.3, but somehow it hung while writing something and rebooted. Now I get a 404 on the GUI. I logged in via ssh and attempted to do a tftp upgrade like:

Code: Select all: # cmdline admin@GK_netonix:/www# tftp 10.1.10.7 -g -r wispswitch-1.3.3.bin -l /tmp/wispswitch-1.3.3.bin admin@GK_netonix:/www# ls /tmp TZ fstab lock resolv.conf run sfpstatus wispswitch-1.3.3.bin config lacpportstatus.json log resolv.conf.auto running-config.json state admin@GK_netonix:/# firmware_upgrade /tmp/wispswitch-1.3.3.bin tar: removing leading '/' from member names Unpacking firmware ... Running preflash script ... Unlocking /dev/mtd8 ... Writing from redboot_recovery_config to /dev/mtd8 ... Could not open mtd device: linux Can't open device for writing! Error flashing kernel

ruh-roh, no? Sounds bad. Here's how my filesystem is mounted.

Code: Select all: admin@GK_netonix:/# mount rootfs on / type rootfs (rw) /dev/root on /rom type squashfs (ro) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) tmpfs on /tmp type tmpfs (rw,nosuid,nodev) tmpfs on /dev type tmpfs (rw) devpts on /dev/pts type devpts (rw,mode=600) /dev/mtdblock6 on /jffs type jffs2 (rw) mini_fo:/jffs on / type mini_fo (rw) admin@GK_netonix:/#

Tried a reboot. Same issue. How screwed am I? How would I mount/recover that flash partition? Here's what I have:

Code: Select all: admin@GK_netonix:/www# cat /proc/mtd dev: size erasesize name mtd0: 00040000 00040000 "RedBoot" mtd1: 00040000 00040000 "config" mtd2: 00140000 00040000 "linux_recovery" mtd3: 00200000 00040000 "rootfs_recovery" mtd4: 00140000 00040000 "linux" mtd5: 00600000 00040000 "rootfs" mtd6: 00440000 00040000 "rootfs_data" mtd7: 00040000 00040000 "FIS directory" mtd8: 00001000 00001000 "RedBoot config" mtd9: 00040000 00040000 "Redundant FIS"

This should be recoverable.

tftp the upgrade file as you did before, then issue these commands:

cd /tmp
tar -xjf wispswitch*.bin
mtd -p write kernel.img /dev/mtd4
mtd -q write fisdir /dev/mtd7
mtd -q write redundant_fisdir /dev/mtd9
mtd -p write rootfs.img /dev/mtd5
mtd -q write redboot_config /dev/mtd8
reboot

Then you should be back up and running.

The weird thing is I logged back in and there doesn't seem to be much mounted space, so:

Code: Select all: admin@GK_netonix:/www# df -h Filesystem Size Used Available Use% Mounted on rootfs 1.2M 1.2M 0 100% / /dev/root 1.2M 1.2M 0 100% /rom /dev/mtdblock6 4.3M 796.0k 3.5M 18% /jffs mini_fo:/jffs 1.2M 1.2M 0 100% /

So I get write errors now when trying to write to /tmp now. Tried reboot and same mount df -h scenario. Is there some way I can mount some filesystem to use temporarily while I restore stuff and/or create a blank part of the filesystem on the flash somewhere?

/tmp is, well, temporary, and should be cleared after each reboot, so you should have plenty of space. /tmp doesn't show up in df, its limited by the amount of RAM.

Right, well when I tried tftp to the /tmp folder, it just timed out, will re-attempt. Edit: it looks like I was having routing issues to my tftp server, so it didn't write the file to /tmp because it didn't get it off the server.

In case anyone else is trying this, here's what it looks like. Some of the steps take a few minutes to complete, hence the progress percentage:

Code: Select all: admin@GK_netonix:/tmp# tar -xjf wispswitch-1.3.3.bin admin@GK_netonix:/tmp# ls TZ kernel.img postflash.sh redundant_fisdir run version.txt config lacpportstatus.json preflash.sh resolv.conf running-config.json wispswitch-1.3.3.bin fisdir lock redboot_config resolv.conf.auto sfpstatus fstab log redboot_recovery_config rootfs.img state admin@GK_netonix:/tmp# mtd -p write kernel.img /dev/mtd4 Unlocking /dev/mtd4 ... Writing from kernel.img to /dev/mtd4 ... 23% 46% 69% 93% 100% admin@GK_netonix:/tmp# mtd -q write fisdir /dev/mtd7 Unlocking /dev/mtd7 ... Writing from fisdir to /dev/mtd7 ... admin@GK_netonix:/tmp# mtd -q write redundant_fisdir /dev/mtd9 Unlocking /dev/mtd9 ... Writing from redundant_fisdir to /dev/mtd9 ... admin@GK_netonix:/tmp# mtd -p write rootfs.img /dev/mtd5 Unlocking /dev/mtd5 ... Writing from rootfs.img to /dev/mtd5 ... 4% 8% 12% 17% 21% 25% 29% 34% 38% 42% 46% 51% 55% 59% 63% 68% 72% 76% 80% 85% 89% 93% 97% 100% admin@GK_netonix:/tmp# mtd -q write redboot_config /dev/mtd8 Unlocking /dev/mtd8 ... Writing from redboot_config to /dev/mtd8 ... admin@GK_netonix:/tmp# reboot

Note: in general, it takes a couple minutes to do a full reboot, so have patience. On another note, I think this process reset my network settings, so since I'm remote, I'll have someone reset it to what I had so I can continue configuration.

After the reboot, I can't seem to login to the unit on the default 192.168.1.20 or the IP I set it to of 10.1.10.x. At this point do I need to get console? If so, do I need a standard serial cable, or a crossover? Hopefully I can get this unit working again.

You need a crossover serial cable.

ok, and what should I be looking for once I login? Should I just use ifconfig to try to set the IP (assuming my filesystem seems basically sane) and try to login via web, or should I try something specific?

You will be in the CLI when you console in
Just use the "?" for help

I would assume you would want to look at the running config

Here is a screen grab of a recent topic where the user could not seem to find how to change from DHCP to Static mode in the CLI so I helped with this picture of how easy it is.

finally got my female/female 9-pin serial null modem from Amazon.

I have a Tripp-Lite Keyspan USA-19HS USB -> Serial 9-pin converter. (in case anyone else is trying this)

I connected (after installing the Windows driver for the USB -> serial converter) using PuTTY with

115200 baud
COM3

(BTW, normal Mac screen /dev/tty.USA19H141P1.1 115200 doesn't work like it works on Cisco console, in case anyone tries that)

and now I have a prompt that says:

Code: Select all: RedBoot>

'diag' passed fine. 'version' shows 1_18_Vitesse

So I tried 'reset' and it shows:

Code: Select all: RedBoot> reset +M25PXX : Init device with JEDEC ID 0x202018. Luton26 board detected (VSC7425 Rev. D).

Should I force the decompress, or how would I get an updated image for 'fis' linux? tftp doesn't seem to be working as a command.

Here's what 'fis' thinks it has available:
