Firmware Transfer between two IOC modules
When the TimeProvider receives the ACT-SWDL command, it automatically logs all
users off of the system and locks the system against new logins. If the firmware
upgrade is an IOC to IOC transfer, and if the target IOC is not active, firmware is
transferred to the target IOC. The system remains locked against logins at this
point. The target IOC reboots after transfer is complete. If the transfer cannot be
completed, the unit returns an error response and the IMC module returns to normal
operation.
Note: The Ymodem file receiver is not used in IOC-to-IOC firmware
transfers.
Example 1
In this example, the ACT-SWDL command is issued to download a firmware file to
the IMC module, but the firmware download is not initiated within 60 seconds.
Notice the Progress Indicator that follows the in-process response. The unit returns
a string of "C's" (
time, to indicate that the IMC module is waiting for an external Ymodem file sender
to initiate the download process:
Input
ACT-SWDL::IMC:TP1000;
