To create a bootable LocalDirector diskette, use one of the following procedures, based on the operating system of your computer.
Follow this procedure to create a bootable LocalDirector diskette if your computer is running the UNIX operating system:
Step 1 Download the file ldxxx.bin from the CCO web site (see the section "Obtaining LocalDirector Software" for instructions).
Step 2 Change to the directory where you saved the ldxxx.bin file.
Step 3 Insert a diskette into the workstation drive, and use the following command:
dd bs=18b if=./ldxxx.bin of=/dev/rfd0
Step 4 Follow the upgrade procedure that is appropriate for your type of LocalDirector configuration (see the section "Performing the Upgrade").
Follow this procedure to create a bootable LocalDirector diskette if your computer is a PC:
Step 1 Download the file ldxxx.exe from the CCO web site (see the section "Obtaining LocalDirector Software" for instructions).
Step 2 Double-click ldxxx.exe to extract its contents.
Step 3 Use the rawrite command at a DOS command prompt. When prompted, enter ldxxx.bin as the filename, and your diskette drive as the destination drive. You will see prompts similar to the following:
C:\LDSoftware>rawrite
RaWrite 1.2 - Write disk file to raw floppy diskette
Enter source file name: ldxxx.bin
Enter destination drive: a:
Please insert a formatted diskette into drive A: and press -ENTER-:
Number of sectors per track for this disk is 18
Writing image to drive A:. Press ^C to abort.
Track: 22 Head: 1 Sector: 16
Done.
Step 4 Follow the upgrade procedure that is appropriate for your type of LocalDirector configuration (see the section "Performing the Upgrade").
This section contains the upgrade instructions for the following types of LocalDirector configurations:
| Caution uring the LocalDirector upgrade, you will lose all existing network connections. We recommend that you perform the upgrade procedure when you impact the least number of users. |
Follow this procedure to upgrade a standalone LocalDirector:
Step 1 Make a backup copy of your configuration by saving it to diskette with the write floppy command or to a TFTP server (see the tftp-server command reference page in Chapter 6, "Command Reference").
Step 2 Insert the floppy disk with the upgrade software in LocalDirector (see the section "Creating a Boot Diskette" if you do not have your boot diskette).
Step 3 Reboot LocalDirector or use the reload command.
As part of the boot sequence, LocalDirector compares the version of software on the diskette against the version residing in Flash RAM. If the version on the diskette is newer, it is copied to Flash RAM, overwriting the older version. The reboot process can take from 1 to 2 minutes.
After the reboot is complete, remove the floppy and store it in a safe place.
The new software version starts up, using your existing network configuration.
Step 4 Use the write mem command to update the version number in the configuration file.
Step 5 Check that your network configuration is running normally. Use the show interface command and ping the real servers.
| Caution Unless your LocalDirector configuration uses stateful failover, during the LocalDirector upgrade you will lose all existing connections. If your site does not use stateful failover, we recommend that you perform the upgrade procedure when you impact the least number of users. To configure stateful failover, see the section "Stateful Failover Implementation" in "LocalDirector Failover," for more information. |
Follow this procedure to upgrade LocalDirector configured for failover:
Step 1 Make a backup copy of your configuration by saving it to diskette with the write floppy command or to a TFTP server (see the tftp-server command reference page in Chapter 6, "Command Reference").
Step 2 On the primary LocalDirector, use the following commands to configure the syslog facility:
LocalDirector(config)primary# syslog output 20.7
LocalDirector(config)primary# syslog console
Step 3 On the secondary LocalDirector, insert the floppy disk with the upgrade software (see the section "Creating a Boot Diskette" if you do not have your boot diskette).
Step 4 Reboot the secondary LocalDirector or use the reload command.
As part of the boot sequence, LocalDirector compares the version of software on the diskette against the version residing in Flash RAM. If the version on the diskette is newer, it is copied to Flash RAM, overwriting the older version. The reboot process can take from 1 to 2 minutes.
Step 5 After the secondary LocalDirector successfully reboots, the primary LocalDirector automatically copies the network configuration to it.
| Caution To ensure a successful upgrade, do not interrupt the configuration copy process. Be sure the copy is complete before proceeding with the upgrade procedure. |
Step 6 Check the progress of the copy process by viewing the SYSLOG messages on the primary LocalDirector.
Messages similar to the following display for a nonstateful failover configuration:
LocalDirector(config)primary# <162> Primary: Power failure other side.
<162> Primary: Cable OK.
<162> Primary: Monitoring on interface 3 waiting
<162> Primary: Monitoring on interface 0 waiting
<162> Primary: Begin Configuration Replication: Sending to mate
<162> Primary: End Configuration Replication
Messages similar to the following display after the above messages when stateful failover is configured:
<165> Begin Stateful Connection Replication: Sending to mate
<162> Primary: Monitoring on interface 3 normal
<162> Primary: Monitoring on interface 0 normal
<165> End Stateful Connection Replication
Step 7 From the primary LocalDirector, use the show failover command to check failover status is normal.
Step 8 From the secondary LocalDirector, use the failover active command to make the secondary LocalDirector the active LocalDirector.
With the secondary LocalDirector active, you can upgrade the primary LocalDirector, which is now in standby mode.
Step 9 From the primary LocalDirector, insert the floppy disk with the upgrade software.
Step 10 Reboot the primary LocalDirector or use the reload command.
As part of the boot sequence, LocalDirector compares the version of software on the diskette against the version residing in Flash RAM. If the version on the diskette is newer, it is copied to Flash RAM, overwriting the older version. The reboot process can take from 1 to 2 minutes.
Step 11 After the primary LocalDirector successfully reboots, the active secondary LocalDirector automatically copies the network configuration to the standby primary LocalDirector.
| Caution To ensure a successful upgrade, do not interrupt the configuration copy process. Be sure the copy is complete before proceeding with the upgrade procedure. |
Step 12 Check the progress of the copy process by viewing the SYSLOG messages on the active LocalDirector.
Step 13 From the primary LocalDirector, use the show failover command to check failover is operating normally and ping the real servers to test connectivity.
Step 14 On the primary LocalDirector, use the following commands to reset the syslog facility:
LocalDirector(config)primary# syslog output 20.3
LocalDirector(config)primary# no syslog console
Step 15 After the upgrade is complete, remove the upgrade floppy diskette and store it in a safe place.
To upgrade software using a boot image contained on a TFTP server, refer to the tftp-server command reference page in Chapter 6, "Command Reference" to obtain your upgraded boot image.
Follow the procedure in the section "Performing the Upgrade," but use the TFTP boot image instead of the image on the floppy diskette.
