Run anything here at your own risk. From what I can tell they should be fairly safe. Do make sure you run them on the switch itself. Pretty nice in case you don’t want to shell out for a Brocade branded USB stick to transfer firmwares!
I found a description how to format a USB-Stick that could be accessed
by the brocade OS.
In fact after some investigation I noticed an error of this description
that prevents to
access this special configured stick.
To make life easier I modified the /sbin/hotplug script by adding one line.
Now any USB-Stick may be used for installation or backup purposes.
The modified hotplug script adds the VENDOR string to
/etc/fabos/usbstorage.conf if the vendor is unknown.
If you redo the “usbstorage -e” command the previously unknown Vendor
stick is been recognized by hotplug
and the activation of the access succeeds!
It might be annoying to do the activation of a stick twice but this has
to be done only if the vendor of the
usb-stick is new for your brocade switch.
Fabos is capable to handle VFAT32-formatted sticks.
The stick needs 5 directories (1 and 4 children):
Here is the diff
# diff hotplug.orig hotplugThe above output means – “Add the ‘echo … ‘ bit on line 62”
> echo “VENDOR $vendor” >> $USBCONFIG
All stuff is been tested with FOS v7.4.2f.
Insert stick in a switch and run this script as root:
#!/bin/bash -x insmod /lib/modules/default/kernel/drivers/usb/core/usbcore.ko insmod /lib/modules/default/kernel/drivers/usb/host/hcd-driver.ko insmod /lib/modules/default/kernel/drivers/usb/storage/usb-storage.ko sleep 10 lsmod | grep usb /bin/mknod -m 660 /dev/sda b 8 0 /bin/mknod -m 660 /dev/sda1 b 8 1 /bin/mknod -m 660 /dev/sda2 b 8 2
Sometimes the above script fails and you need to run it until it has usb_storage and usbcore modules listed as loaded kernel modules.
Now I can mount an ext3 formatted USB-stick:
# mkdir /usb_ext3 # mount -t ext3 /dev/sda1 /usb_ext3 # ls /usb_ext3/ bin/ dev/ fabos/ libexec@ sbin/ tftpboot/ var/ boot/ diag@ import/ mnt/ share@ tmp/ config/ etc/ initrd/ proc/ standby_sbin/ users/ core_files/ export/ lib/ root/ support_files/ usr/ # mkdir /usb_vfat # mount -t vfat /dev/sda1 /usb_vfat # ls /usb_vfat/ .Trash-1000/ brocade/ config/ firmware/ firmwarekey/ hda1.dmp* support/
I’ll stop here at the moment because now I need to know how u-boot
starts an OS from an USB-stick…
