Upgrading an Affinity using a USB stick

Requirements

Procedure

  1. Do not connect the USB cable or stick at this time.

  2. Log in to the DAS as root.

  3. Issue the following commands, which will switch off automatic disk access. Ignore any errors or messages:

    svc Pt-storage stop svc rdisk stop
  4. Allow a few seconds for the power lines to settle.

  5. Issue the following commands, to turn on power to the USB stick. Ignore any errors or messages:

    ioline -L usb_otg -o 1
  6. Connect the USB cable and the USB stick.

  7. Mount the USB stick with the command:

    mount -o ro -t ext2 /dev/sda1 /mnt

    This should not produce any output, signifying that it has worked. If you do see any error message, try the following:

    • Wait ten seconds

    • Try repeating the command with ext2 changed to ext3 or ext4

    • Check the kernel log to see what the device was called by issuing the following command:

      dmesg

      In the last few lines of output there should be something like:

      sd 46:0:0:0: [sda] 15826944 512-byte logical blocks: (8.10 GB/7.54 GiB) sd 46:0:0:0: [sda] Write Protect is off sd 46:0:0:0: [sda] Mode Sense: 43 00 00 00 sd 46:0:0:0: [sda] Assuming drive cache: write through sd 46:0:0:0: [sda] No Caching mode page present sda: sda1 sd 46:0:0:0: [sda] Assuming drive cache: write through sd 46:0:0:0: [sda] Attached SCSI removable disk

      Check that the token in the output, sda1 above, matches the token in the command: /dev/sda1. If, instead, you see sbd1 in the dmesg output, then you should use /dev/sdb1 in the mount command. (This might be the case if your Affinity has a Compact Flash module, which would have been allocated sda, forcing the upgrade pod to be sdb.)

    If this still fails, the unit will need to be upgraded by some other method.

  8. Run the command:
    /mnt/upgrade
  9. Wait until you see the message

    =================================== Upgrade complete, please reboot now ===================================

    then reboot the Affinity by interrupting the power or entering the command:

    reboot
