Updating CMM Software
direction=$2
if [ "$direction" = "forward" ] ; then
cp /home/stagingarea/myScript.new /home/scripts/myScript
elif [ "$direction" = "backward" ] ; then
cp /home/stagingarea/myScript.old /home/scripts/myScript
fi
exit $?
When the update process executes, and the Data Restore User Scripts are executed (during the
update of the /etc partition), then the script S10updateMyScript will be executed and /home/script/
myScript will be updated accordingly.
Variation on the above example:
• In this case, the different versions of myScript are put on the CMM (by the user) as:
— /home/stagingarea/myScript.A
— /home/stagingarea/myScript.B
— /home/stagingarea/myScript.C
Note: If the CMM has build A installed, the "cmmget -d version" command will return the string "A" -
and so on for builds B and C.
Another example of S10updateMyScript :
#!/bin/bash
newversion=$4
cp /home/stagingarea/myScript.$newversion /home/scripts/myScript
exit $?
23.14 Update Process
1. Client initiates an update request via CLI command
2. CMM validates the update request
— CMM is not already doing an update
— Enough space is present in ramdisk and flash for the update
3. If update request is valid then
— Continue
4. Else
—Exit
5. If FTP arguments supplied then
— Retrieve package files (.zip, .md5) from FTP server
— Exit if error occurs
6. Else
— Copy package files (.zip, .md5) to package directory on ramdisk (/usr/local/cmm/temp/
update/package)
