Cisco MDS 9000 Series EPLD Release Notes, Release 9.4(1a)

 

Introduction

Switches and directors in the Cisco MDS 9000 Series contain several electrical programmable logical devices (EPLDs) that provide hardware functionalities in all the modules. EPLD upgrades are periodically provided to include enhanced hardware functionality or to resolve known issues.

EPLD bundles are released as part of a Cisco MDS NX-OS release. Therefore, the EPLD bundles have a version number that matches the Cisco MDS NX-OS release they are part of.

An EPLD bundle is a package containing updates for multiple EPLDs. Each EPLD update has its own version number, which is independent of the Cisco MDS NX-OS release. As EPLD changes are infrequent, an EPLD bundle may contain new updates for only some EPLDs. The remaining EPLD updates will be the same version as the previous EPLD bundle.

You need not update switch EPLDs unless otherwise advised by TAC. For detailed functional image upgrade instructions, refer to the Cisco MDS 9000 NX-OS Fundamentals Configuration Guide, Release 9.x. To download EPLD bundles, go to the URL: https://software.cisco.com/download/navigator.html.

EPLD Bundle Support Matrix

The version of the EPLD bundle must match the version of the Cisco MDS NX-OS release that is running when the EPLD upgrades are installed. This requirement only applies during EPLD code upgrades or downgrades. Cisco MDS NX-OS can be subsequently upgraded or downgraded without changing the EPLD versions.

The following table shows the EPLD bundles that are compatible with specific NX-OS releases.

Table 1.           Release Compatibility Matrix

The following table lists the Cisco MDS 9000 components and the EPLD bundle versions that are supported for the components.

Table 2.           EPLD Support Matrix

Guidelines and Limitations

When you upgrade or downgrade the EPLDs, observe the following guidelines and limitations:

●     You can upgrade each module only when it is online. The EPLD upgrade is only disruptive to the module being upgraded.

●     If you interrupt an EPLD upgrade or downgrade, the module must be upgraded again.

●     In Cisco MDS 9000 Director Switches, EPLD upgrade or downgrade can only be executed from the active supervisor module. To upgrade the supervisor EPLDs nondisruptively, upgrade the standby supervisor and then switchover. After the new standby supervisor is online, its EPLDs can be upgraded.

●     In Cisco MDS 9000 Series Fabric Switches, be sure to specify 1 as the module number. The switch must be power cycled for the EPLDs to start running the new code.

Determining EPLD Versions

Installing EPLD Updates

Supervisors, switching, fabric, and fan modules may be upgraded in a switch. For Director switches, modules can be upgraded together or individually. For Fabric switches, modules are upgraded individually. Fabric switches do not require fabric and fan modules to be upgraded.

The modules to be upgraded are specified by the user. If the module number that is specified in the command is not present, the update is aborted. Otherwise, a warning and a prompt to continue is printed. If the user proceeds, the status of each specified module is printed followed by a table of installed and new EPLD versions. If no modules require upgrading, the command exits. If any module EPLD version is different and requires upgrading, the user is prompted to continue. All EPLDs are updated on the first specified module. The update process may take several minutes. After the update, the module is power cycled. For switching modules, this power cycle disrupts traffic on all ports of the module. If the new EPLD version is the same as the installed version or the module is present but not online, no action is taken for that module. If more than one module is specified, the download and power cycle process is repeated for the next module.

This section includes the following topics:

Installing EPLD Updates on All Modules in a Director Switch

To update all EPLDs sequentially with a single command, use the install all epld command with the module all fan-module all xbar all options. After each module is upgraded, it is power cycled to load the EPLD update. Switching module power cycles are disruptive to the traffic passing through them. If the active supervisor requires upgrading, it will be updated last and a supervisor switchover executed. Fan modules do not require to be power cycled.

Installing a Director Switch Supervisor Module EPLD Update

To update the EPLDs on supervisor modules of Director Switches in a nondisruptive manner, follow these steps:

Step 1. Update the EPLD on the standby supervisor module. On the active supervisor module, enter the install all epld command, specifying the current standby supervisor module number.

After the EPLD update is complete, the standby supervisor module will be power cycled.

Step 2. After the standby supervisor module reaches the 'ha-standby' state, perform a switchover and wait until the new standby supervisor module reaches the 'ha-standby' state.

Step 3. From the active supervisor module, repeat the above steps.

For information about how to update the EPLDs on supervisor modules of the Fabric switches, see Installing a Switching Module EPLD Update.

Installing a Switching Module EPLD Update

For Director Switches, use the install all epld uri parallel module slot command to update the EPLDs on an individual module. Use the module all option to update the EPLDs of both supervisors and all switching modules.

*************************************

Installing a Fabric Switch Supervisor EPLD Update

Note:       An EPLD update of the supervisor module of Fabric Switches (Cisco MDS 9100, Cisco MDS 9200, and Cisco MDS 9300 Series switches) is disruptive since there is no redundant supervisor to take over while the update is in progress. All traffic through the system is stopped while updating and the switch is power cycled after the upgrade has been completed. The update may take up to 30 minutes to complete.

The following message is displayed:

Data traffic on the switch will be affected!!
The switch will reload after the upgrade process.

Installing a Fan Module EPLD Update

Use the install all epld uri parallel fan-module slot command to upgrade the EPLDs on the fan modules. The EPLD update for a fan module is nondisruptive and a power cycle is not required after the update.

Upgrading Fan Module EPLDs on a Cisco MDS 9700 Series Switch

WARNING!!!: Executing the "install all epld" command

It is strongly recommended to use one of the following

1) "install module <mod#> epld"

2) "install all epld <uri> parallel module <mod#>"

Installing a Fabric Module EPLD Update

The Cisco MDS 9700 Series switches have dedicated fabric modules. These modules contain EPLDs, which can be upgraded as described in this section. All other Cisco MDS switches do not have these modules, so this process is not applicable to them.

For Cisco MDS 9700 Series switches, use the install all epld uri parallel xbar-module slot command to update the EPLDs on the fabric modules. This process power cycles the updated module. To ensure that the data traffic performance is not affected while the module is power cycled, check the fabric bandwidth utilization by using the show hardware fabric-utilization detail command. If there is adequate reserve fabric bandwidth available before the update starts, then the update will be nondisruptive.

Upgrading Fabric Module EPLDs for a Cisco MDS 9700 Series Switch

switch# install all epld bootflash:m9000-pkg2.9.4.1a.epld parallel xbar-module 1

 

WARNING!!!: Executing the "install all epld" command

may result in multiple modules going offline and

affect redundant links.

 

It is strongly recommended to use one of the following

when EPLD upgrade is attempted on a system carrying

production traffic.

 

1) "install module <mod#> epld"

2) "install all epld <uri> parallel module <mod#>"

where <mod#> is on a single module
