AXP1440-C07 Shelf Installation
AXP1440-C07 Shelf Installation
One way of doing this is:
# scp acctname@fileserver_ip:dirname/sentry.shmm1500.* /tmp
where:
acctname
is the login account for the user on the (Linux) file server
fileserver_ip
is the IP address of the file server
dirname
is the relative directory name (from the login home) for the location of the
images
2. Verify that the files were copied to
/tmp
.
3. Execute the command to program these images into flash and then reset to execute
the new images:
# rupgrade_tool -s -v -d -a [--hook=erase]
The
--hook=erase
argument is optional, and is normally not used. This directs the
upgrade procedure to avoid preserving the customer-specific configuration files,
/etc/shelfman.conf
and
/etc/shelfman.conf.sam1500
. Normally, these files
should be preserved across an upgrade, but on occasion, when SMART EC makes
a change to the format of the configuration options, you may be instructed to use
this option. In this case, you need to re-enter the configuration by editing these
files, following the upgrade.
The default configuration of the shelf managers in the AXP1440-C07 is to perform
a switchover when opening the handle switch. To prevent the premature failover of
the shelf managers, modify the SWITCHOVER_ON_HANDLE_OPEN variable in
/etc/shelfman.conf.sam1500
to FALSE.
The files are copied to flash memory and the system reboots in a few minutes.
When the system is restarted, the boot up logic automatically determines if the
SAM1620-D FPGA needs to be loaded to a new firmware revision. If so, an
additional upgrade and reboot takes place and takes an additional 5-8 minutes.
The SAM should now be running the new firmware.
4. The process can now be repeated with the other shelf manager.
NOTICE
If --hook erase option is used during the software update, the
SWITCHOVER_ON_HANDLE_OPEN parameter will return to TRUE, following an
upgrade of the shelf manager’s software. In such a case, set the value of
SWITCHOVER_ON_HANDLE_OPEN to FALSE manually.
