Committing new firmware

Reverting to old firmware

D20MX INSTRUCTION MANUAL
After new firmware has been downloaded (either via serial or network connection), and the
D20MX has restarted and is operating correctly, the firmware must be "committed" to the
secondary storage.
Once the new firmware is committed, you cannot revert to the old version of the firmware;
see Section: "Reverting to old firmware" on page 69.
To commit new firmware:
1. Login as a user that has Maintenance or Read/Write access privileges.
2. Enter the D20M Shell.
3. Enter the commit command.
Result: A prompt appears to confirm copying the firmware from Primary to Secondary.
4. Enter yes to confirm the copy operation. If anything else is entered, the command is
canceled.
Result: The firmware copy operation begins. Both 'vxworks' and 'appl.out' are copied.
This operation takes approximately 3 minutes.
DO NOT shut off the power to the D20MX while the copy operation is in progress. If power
to the D20MX is disrupted, during the copy operation, the firmware is likely to be corrupted.
If the D20MX is configured for device redundancy, perform this procedure on the standby
unit. Then if desired, switch over and perform this on the other unit.
A previously committed version of the firmware (i.e., old firmware) may be recovered from
secondary storage.
This feature is intended to be used if, after downloading a new version of the firmware, an
issue is identified and you wish to recover the previous version of the firmware. A revert is
only possible if the new firmware has not been committed; see Section: "Committing new
firmware" on page 69.
To revert the firmware:
1. Login as a user that has Maintenance or Read/Write access privileges.
2. Enter the D20M Shell.
3. Enter the revert command
Result: A prompt appears to confirm copying the firmware from Secondary to Primary.
4. Enter yes to confirm the copy operation. If anything else is entered, the command is
canceled.
Result: The firmware copy operation begins. Both 'vxworks' and 'appl.out' are copied.
This operation takes approximately 3 minutes.
DO NOT shut off the power to the D20MX while the copy operation is in progress. If power
to the D20MX is disrupted, during the copy operation, the firmware is likely to be corrupted.
5. Once the copy operation has completed, enter the boot command to restart the
D20MX with the reverted firmware.
