In this section:
Upgrading the DSC 8000
Screen captures, images, and code on this page are examples only and are the same between releases with the exception of the software version numbers.
Do not log onto the system using the shared IP addresses on the Management CPUs during the upgrade processes. These addresses are disabled as part of this process.
It is recommended that you perform the upgrade from a console port. A loss of connection while CPUs are being upgraded may require a rollback from the upgraded management CPU.
Workflow
You must upgrade the DSC 8000 system cards in the following order: (1) CPUs, (2) MCH Ethernet Switches, and (3) IO cards.
Upgrade the Software on the CPUs
Start
Log onto the DSC 8000 Management CPU in slot 13 (p19p2.5, Control shelf) or slot 2 (p19p1.3).
NoteYou must log onto the same CPU as the one you connected to upload the _upgrade.sh file.
Run command "upgrade" and press ENTER.

- Continue to upgrade all CPUs. After the software upgrade is completed on the CPUs, ensure that the upgrade was successful and the software was properly installed by continuing to the next section.
Verify the CPU Software has been Properly Installed
If an asterisk appears beside any of the system cards during the verification process, the upgrade for the respective card was unsuccessful. In this case, it is recommended that you contact Customer Support.
Start
- At the Linux prompt, enter startmenu, and press ENTER.
- Select System, and press ENTER.
- Select Software Revisions, and press ENTER.
- Select CPU Versions, and press ENTER
Make sure that the software and OS have been upgraded, all cards are running the same software, and that there are no asterisks beside any of the cards.
TipThe output of the “CPU Versions” command shows that the CPU card has “UPGRADED” status if this is the first time the command is issued after an upgrade. All subsequent “CPU Versions” commands show the number of processes running on each CPU.

Upgrade the Software on the IO Cards
Execute both of the following procedures in order to upgrade the software on the IO cards.
Verify the Health of the IO Configuration Files
Use this procedure if the system contains IO cards. This procedure executes a health check script that verifies the existence of the mp_mtp2.conf.slotX files on the IO card as well as its synchronization to the management CPU card (X is the IO slot number).
Start
- Log onto a Management CPU.
Enter "health_check_io.sh X" to execute the health check script.
NoteX is the IO number.
This command should be executed for each IO.
- The script produces a health check result, which is either PASS or ERROR.
- If the result is ERROR, proceed to step 4 and 5.
- If the result is PASS, proceed to step 6.
- If the result is ERROR, the issue is either missing or mismatched files on the IO card.
- When an issue is detected, the script allows the user to copy the necessary files from the management CPU card to the IO card. If all the files are retrieved successfully, then the result will be PASS.
If the health check result is PASS, proceed to the next section: To Upgrade the software on the IOs
Only proceed to the upgrade IO card progress if the health check result is PASS.

Upgrading the Software on Spare System Cards
The spare MCH and IO cards software can be updated when they are needed to replace a failed card. The cards are difficult to remove from the system, so do not attempt to remove the cards unless it is necessary. Contact Customer Support for assistance to upgrade the cards.
Some of the system cards may be equipped with a yellow guard. You must remove these guards before inserting the respective card into the chassis’ slot. For more information, see the appropriate chapter in the DSC 8000 Hardware Installation Guide.
Post Upgrade Processes
After the software upgrade is completed and considering any feature changes, validate the upgraded system.
Verify the system configuration and data recorded before the upgrade. See Collecting Common System Status Information. If there are discrepancies in the system prior to and after upgrade, contact Customer Support before considering a software rollback.
A software rollback process only should be performed in case severe issues occur shortly after the software upgrade. Any provisioning or configuration changes that have been made after an upgrade are lost during a rollback process.
Update MIBs Files on Trap Receivers
It is highly recommended that the new MIBS be downloaded from the upgraded system and compiled on the Trap Host. New features and parameters may exist in the new software that would not be contained in the older release MIBS. MIBS can be downloaded by logging into the WEB Interface and clicking on File Retrieval, and then clicking on the MIBS tab.
For information about obtaining the MIB files, refer to MIB Files.
Continuing Upgrade After Loss of Connection
In the event the upgrade is performed via ssh to the DSC management CPU and a loss of connection is suffered while the CPU upgrade is in progress, you may continue the upgrade after reconnecting.
Restart the Upgrade
To restart an in progress upgrade after connection loss, reconnect to the direct IP of the management CPU the upgrade was initially started from and issue the 'upgrade' command again.
Always select option A (Continue that upgrade process using the same backup) as seen in the example below. Never select option B unless directed to do so by Customer Support.
When continuing a previous upgrade, some differences occur, as shown below:

Rolling Back a Partial Upgrade
If the loss of connection is not resolved with sufficient time left in the maintenance window to complete the upgrade, you will need to rollback from the newly upgraded management CPU.
Rolling back from a partial upgrade must be completed as soon as connection can be restored to the DSC. No changes should be made on the DSC while in a partially upgraded state.
One of the two management CPUs will ALWAYS be the first card upgraded. You will need to ssh to that CPU's direct IP and follow the rollback procedure for CPUs found here: Software Rollback Process - DSC 8000
If connection is lost during the upgrade of Switches or IO cards, if the software application verification fails, or the cards demonstrate issues, follow the rollback procedures found in the guide for the affected card(s).
