Our engineers recommend that you back up to tape the data in the signonCount.out 
and signonCount.fixrpt files, as well as the data in the dhctStatus2 directory. You can 
then use this data as a reference and troubleshooting tool in the event that there are 
problems with the system after the upgrade. The instructions in this section guide 
you through the steps of backing up these files. 

 

Follow these instructions to back up the signonCount.out and signonCount.fixrpt 
files, as well as the data in the dhctStatus2 directory. 
1  Label a tape with the date and the following title: 

signonCount / dhctStatus2 Backups

 

2  Insert the tape into the tape drive of the DNCS. 
3  From an xterm window on the DNCS, type the following command and press 

Enter. The system backs up the specified files. 

tar  cvf  [device name]  /dvs/dncs/tmp/signonCount.out  
/dvs/dncs/tmp/signonCount.fixrpt  /dvs/dncs/tmp/dhctStatus2

 

Note:  Substitute the device name of the DNCS tape drive for [device name] How 
to Determine the Tape Drive Device Name (on page 87). 
Example:  

tar  cvf  /dev/rmt/0h  /dvs/dncs/tmp/signonCount.out  

/dvs/dncs/tmp/signonCount.fixrpt  /dvs/dncs/tmp/dhctStatus2

 

4  When the backup is complete, eject the tape and store it in a safe place. 

 

In the event that you ever need to access the pre-upgrade configuration files of the 
QAM-family and QPSK modulators, follow these instructions to make a backup 
copy. 
1  From a root xterm window, type mkdir /tftpboot/backup_4.2_preSP4  and then 

press Enter. 

2  Type cp –p /tftpboot/*.config /tftpboot/backup_4.2_preSP4  and then press 

Enter. The system copies all .conf files to the /tftpboot/backup directory.
