Rollback Procedures
Introduction
After loading the QPSK A63 software, if you notice that the system is reacting
adversely, call Cisco Services. If they determine it is necessary to roll back the
procedure, complete the steps in this section to restore the qpsk.config file and to
deactivate the signonCount utility.
Important: Do not initiate these rollback procedures before contacting Cisco
Services.
Restoring the qpsk.config Files
To restore the qpsk.config files, complete the following steps.
1.
From an xterm window on the DNCS, log in as root user.
2.
Type cd /tftpboot and Enter.
Result: The /tftpboot directory becomes your working directory.
3.
Type cp -p qpsk.config.<xxx> qpsk.config and Enter.
Note: Replace the <xxx> in this entry with the number of the QPSK software
version number you entered in step 5 of the Install QPSK A63 Software Onto
the DNCS procedures, earlier in these instructions.
Example: cp -p qpsk.config.A55 qpsk.config
Result: The system restores the original qpsk.config file.
4.
Use the Download QPSK A63 Software to the QPSK Modulators
procedures, earlier in these instructions, to reboot each QPSK modulator on
your system.
Deactivating the signonCount Utility
Deactivating the signonCount utility stops it from running in the background. To
stop the signonCount utility, deactivate it by completing the following steps.
1.
Check if the signonCount utility is currently running. From an xterm window
on the DNCS, type ps –ef |grep sign and Enter.
Result: If the signonCount utility is currently running, a message appears
similar to the following:
/bin/ksh /dvs/dncs/bin/signonCount.ksh
If the message does not appear, then signonCount is not running. You do not
need to perform step 2.
2.
If the signonCount utility is running in the background and you want to
deactivate it, from an xterm window on the DNCS, type signonCount
uninstall and Enter.
Result: The following message appears: ―SignonCount‖ has been removed as
a background process.
