Errorless Upgrades and Exceptions

This section describes important information to be aware of before you begin the upgrade process:

    Document Procedures

    Procedures in this document must be performed in consecutive order unless noted otherwise. Ensure that the procedure is completed for each node in a given network. If you are new to upgrading the software, make a printed copy of this document and use it as a checklist.

    Each non-trouble procedure (NTP) is a list of steps designed to accomplish a specific procedure. Follow the steps until the procedure is complete. If you need more detailed instructions, refer to the detail-level procedure (DLP) specified in the procedure steps. Throughout this guide, NTPs are referred as “procedures” and DLPs as “tasks.” Every reference to a procedure includes its NTP number, and every reference to a task includes its DLP number.

    The DLP (task) supplies additional task details to support the NTP. The DLP lists numbered steps that lead you through completion of a task. Some steps require that equipment indications be checked for verification. When a proper response is not obtained, a trouble clearing reference is provided.

    This section lists the document procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).

    1. NTP-U487 Preparing to Upgrade to a New Release—This procedure contains critical information and tasks that you must read and complete before beginning the upgrade process.

    2. NTP-U488 Back Up the Cisco Software Database—Complete the database backup to ensure that you have preserved your node and network provisioning in the event that you need to restore them.

    3. NTP-U489 Upgrade the Cisco Software—Complete this procedure to complete the upgrade.

    4. NTP-U490 Install Public-Key Security Certificate— Complete this procedure to be able to run the software.

    5. NTP-U491 Restore the Previous Software Load and Database— Complete this procedure if you want to return to the previous software load you were running before activating the new release.

    6. — Complete this procedure only if you want to upgrade to a new release using Transaction Language (TL1).

    NTP-U487 Preparing to Upgrade to a New Release

    Purpose

    This procedure provides critical information checks and tasks you must complete before beginning an upgrade to the latest release.

    Procedure

    Step 1

    Before you begin, make sure that information related to your site, for example, date, street address, site phone number, and dialup number are stored in a safe and accessible location. The data will be useful during and after the upgrade.

    Step 2

    Read the release notes of the release you are upgrading to. Visit Release Notes to download the release notes.

    Step 3

    Ensure your workstation meets the minimum hardware and software requirements before starting the upgrade. For more information on the hardware and software requirements, read the release notes.

    Step 4

    Refer to the to verify if the upgrade path is supported.

    Step 5

    Make sure that the control cards are installed in the appropriate slots on all the nodes in the network and on both the slots as indicated here. For a complete list of supported control cards, see Supported Control Cards:

    Step 6

    Repeat the above step for every node in the network.

    Step 7

    Collect the node diagnostics logs from the node. This action is very useful incase the upgrade fails, as the diagnostics help in understanding if the node had issues before the upgrade.

    Step 8

    Export the current alarms and conditions to your local storage. After the upgrade, if new alarms or conditions arise, then comparing the time stamp of the alarm to the previously saved time stamp helps in identifying new alarms or conditions.

    Step 9

    Perform a backup of the node database. This is very useful incase the upgrade fails, then the database can be restored using the backup. The detailed procedure for backing up the database is discussed in the next section.

    Stop. You have completed this procedure.

    Security Level

    Superuser


    Caution

    Do not perform maintenance or provisioning activities during the activation task.

    Procedure

    Step 1

    Insert the software CD into the workstation CD-ROM drive (or otherwise acquire access to the software) to begin the upgrade process.

    Note

     

    Inserting the software CD activates the CTC Java Setup Wizard. Use the setup wizard to install the components or click Cancel to continue with the upgrade.

    Step 2

    Complete the DLP-U546 Download the Software task for all nodes to be upgraded.

    Step 3

    Complete the DLP-U548 Activate the New Cisco Software task for all nodes to be upgraded.

    Note

     

    Only one node can be activated at a time. During a parallel upgrade, activate another node as soon as the controller cards reboot successfully. To perform parallel upgrade remotely, wait five minutes for the controller cards to reboot completely.

    Step 4

    Complete the DLP-U549 Delete Cached JAR Files task, as necessary.

    Step 5

    (Optional) If you want to prevent a software revert to an earlier software release, complete the DLP-U546 Download the Software task on all nodes, or groups of nodes you are upgrading a second time.

    Step 6

    If you need to return to the software and database you had before activating Software , proceed with the NTP-U491 Restore the Previous Software Load and Database procedure.

    Step 7

    To back up the Software database for the working software load, see NTP-U488 Back Up the Cisco Software Database procedure in order to preserve the database for the current release.

    Stop. You have completed this procedure.

    What to do next

    After upgrading the software to a different build, if there is a change in the FPGA, the FPGA is upgraded automatically. During the FPGA upgrade process, the card goes for a cold reboot. If Optical Supervisory Channel (OSC) is provisioned, then the transient PPM-IMPROPER-REMOVAL alarm is raised, which gets cleared in a short span of time. This happens because of the power glitches to the PPM while the card is coming up after the cold reboot.

    DLP-U546 Download the Software

    Purpose

    This task downloads software to the nodes before activation.

    Tools/Equipment

    PC or UNIX workstation

    Step 8

    To open the folder, choose the file with the PKG extension and click Open.

    Step 9

    From the list of compatible nodes, select the nodes where the software must be downloaded.

    Note

     

    It is recommended that simultaneous software downloads on the section data communications channel (SDCC) be limited to eight nodes at a time, using the central node to complete the download. If more than eight concurrent software downloads are selected at a time, it is placed in a queue.

    Step 10

    Click OK. The Download Status column monitors the progress of the download.

    Step 11

    Return to your originating procedure (NTP).

    DLP-U548 Activate the New Cisco Software

    Purpose

    This task activates the software on each node in the network.

    Tools/Equipment

    PC or UNIX workstation

    Prerequisite Procedures

    DLP-U546 Download the Software

    Required/As Needed

    Required

    Onsite/Remote

    Onsite or remote

    Security Level

    Superuser


    Note

    It is recommended that the first node that is activated be connected via LAN. This ensures that the new CTC JAR files download to the workstation as quickly as possible.

    If a node is provisioned to have no LAN access, the value is overridden in the case of node isolation. Additionally, if the node is not reachable, the LAN access is turned on. It is recommended that you avoid node isolation.


    Note

    During the activation process, when the node is being upgraded to R11.0 (and later releases), the USB-MOUNT-FAIL alarm is raised. In MSM, the USB-MOUNT-FAIL alarm is raised on all subtended shelf controllers and the node controller. When all the subtended shelf controllers and the node controller complete the upgrade successfully, the USB-MOUNT-FAIL alarm is cleared. No manual intervention is required to clear the USB-MOUNT-FAIL alarm. After the USB-MOUNT-FAIL alarm is cleared, USB sync is triggered. After USB sync is successfully completed, the node is migrated to the latest software successfully.

    Procedure

    Step 1

    If CTC is not already started, start CTC.

    Step 2

    Record the IP address of the node. The IP address can be obtained either on the LCD or on the upper left corner of the CTC window.

    Step 3

    Make sure that the alarm filter is turned off. To do so, complete the following:

    1. Click the Filter tool at the lower-left side of the window.

      The Alarm Filter dialog box appears.

    2. Click to select any check box that is not selected in the Show Severity section of the General tab.

    Step 4

    Make sure that all cards that are part of a 1+1 or Y-cable protection group must be active on the working card of the protection group and no protection switches are occurring. Also, ensure that traffic carrying protect cards are in a standby state. To do so, complete the following:

    1. In the node view, click Maintenance > Protection tabs.

    2. Select each protection group listed and view the active or standby status of each card in the Selected Group area.

    Step 5

    In shelf view, click the Maintenance > Software tabs.

    Step 6

    Verify that the version in the Protect Version column is .

    Step 7

    Click the Activate button. The Activate dialog box displays a warning message.

    Step 8

    Click Yes to proceed with the activation.

    During node activation, all the common control cards in the node reboot beginning with the standby card. As soon as the standby card recovers from the reboot, it signals the active card to reset as a standby card and the standby card transitions to active. An Activation Successful message indicates that the software is successfully activated.

    Step 9

    Click OK.

    The connection between CTC and the node is lost and CTC displays the Network view. The INCOMPATIBLE-SW alarm is raised in CTC for the first node that is activated because CTC is unable to connect to the NE due to differing, incompatible versions of the software between CTC and the NE. A CTC alert is displayed to update the CTC software. To clear the INCOMPATIBLE-SW alarm, perform steps 10 through 12 only for the first node that is activated on the network.

    During the activation process:

    • The SYSBOOT alarms are raised when the common control cards and cross-connect card reset. These alarms clears when all the cards reset.

      The activation process can take up to 30 minutes, depending on the number of cards installed in the node.

    • The GCC-EOC, EOC, and EOC-E alarms are transient. These alarms are raised and cleared during the upgrade process when the control cards and line cards reset.

    • Protect cards in the Y-cable protection group boot next, in the order that the protection group was created.

    • Other line cards reset one after the other in the order of slot number.

    If you are upgrading remotely and cannot see the nodes, wait for 5 minutes for the process to complete, then check to ensure that related alarms have cleared before proceeding.

    Step 10

    In CTC, choose File > Update CTC. The CTC software is updated. A CTC alert is displayed to restart CTC.

    Step 11

    In CTC, choose File > Exit.

    Step 12

    Start CTC again.

    Step 13

    Click the Launch CTC button in the CTC launcher window.

    The new CTC applet loads. The login window is displayed.

    Required for revert

    Onsite/Remote

    Onsite or remote

    Security Level

    Superuser


    Note

    To perform a supported (non-service-affecting) revert from , the release you want to revert to must have been working at the time you activated to the current software version on that node. Also, a supported revert automatically restores the node configuration at the time of the previous activation. The exception to this is when you have downloaded a second time, ensuring that no revert to a previous load can take place. In this case, the revert occurs, but is not traffic-affecting and does not change the database.


    Note

    Ensure that all cards that are part of a protection group (1+1 or Y-cable) are active on the working card of that protection group and that no protection switches are occurring. To ensure that traffic carrying protect cards are in a standby state, in the node view click the Maintenance tab, and view the Protect column for each of the listed protection groups. View the active/standby status of each card in the Maintenance tab.

    Procedure

    Step 1

    From the node view, click the Maintenance tab, then click the Software button.

    Step 2

    Verify that the protect software displays the release you upgraded from.

    Step 3

    Click the Revert button. Revert activates the protect software and restores the database from the previous load. A confirmation dialog box appears.

    Note

     

    Any FPGA downgrades during the revert process may affect traffic. Configuration changes made after activation are lost when you revert.

    Step 4

    Click OK. This begins the revert process and drops the connection to the node.

    Step 5

    Wait until the software revert completes before continuing.

    Note

     

    The system reboot may take up to 30 minutes to complete.

    Step 6

    Wait one minute before reverting another node.

    Step 7

    After reverting all the nodes in the network, restart the browser and log back into the last node that was reverted. This uploads the appropriate CTC applet to your workstation.
