Upgrading a DCM using a USB stick
- A USB stick prepared with the
- Cable CAS-DCM-0038.
- Command line access to the DCM (either serial cable or ssh).
- Do not connect the USB cable or stick at this time.
- Log in to the DCM as root.
- Issue the following commands, which will switch off automatic disk access. Ignore any errors or messages:
svc Pt-storage stop svc rdisk stop
- Connect the USB cable and the USB stick.
- Mount the USB stick with the command:
mount -o ro -t ext2 /dev/sda1 /mnt
If this does not work, try the following:
- Ensure you have waited 10 seconds
- Try changing
- Check the kernel log to see what the device was called with the following command:
In the last few lines of output there should be something like:
sd 46:0:0:0: [sdb] 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] Assuming drive cache: write through sda:
sda1sd 46:0:0:0: [sda] Assuming drive cache: write through sd 46:0:0:0: [sda] Attached SCSI removable disk
Check that the token
sda1matches the token in
If this still fails, the unit will need to be upgraded by some other method.
- Run the command:
- Reboot the CMG-DCM.
