Release Notes for Cisco Services Ready Engine Virtualization Release 2.x

November 5, 2014

Cisco Services Ready Engine Virtualization (Cisco SRE-V) is a branch-office infrastructure platform that combines computing, networking, storage access, virtualization, and unified management into a cohesive system. It enables the VMware vSphere Hypervisor to be provisioned on a Cisco Services Ready Engine (SRE) Service Module and to host one or multiple virtual machines running the Microsoft Windows Server or Linux operating systems. The entire system is integrated with the Generation 2 of the Cisco Integrated Services Router (ISR G2).

This document provides system requirements, information about open source software, new and changed information, and open and resolved caveats for Cisco Services Ready Engine Virtualization Release 2.x.

Open Source Software Information

Some components of the software created for Cisco Services Ready Virtualization are provided through open source or commercial licensing.

New Information

Cisco SRE-V Release 2.x supports the following new features:

  • Added new procedure to migrate the Cisco SRE-V software from release 2.0.1 to release 2.x. See Migrating the Cisco SRE-V Software from Release 2.0.1 to Release 2.x.
  • As of October 2013, added support for VMware ESXi 5.1 on the Cisco SRE 710 and 910 modules.
  • Added support for VMware ESXi 5.0 on the Cisco SRE 710 and 910 modules.
  • Added the ability for the Cisco SRE-V host to shut down gracefully when the reset button on the front panel is pressed. This also shuts down the virtual machines. (You can configure a graceful shutdown for virtual machines through the vSphere Client or vCenter Server.)
  • Achieved Microsoft SVVP certification for the Cisco SRE-V Release 2.0 software for Microsoft Windows Server 2008 R2.

Migrating the Cisco SRE-V Software from Release 2.0.1 to Release 2.x

Before You Begin

  • Download the appropriate version of the Cisco SRE-V upgrade software.

Procedure


Step 1 Use the service-module sm slot /0 install url url argument keep-ds command to install the Cisco SRE-V software, as shown in the following example:

Router# service-module sm 2/0 install url ftp://server.com/dir/sre-v-k9-r.SPA.smv.2.0.2.pkg argument keep-ds
 

where url is the server and directory on which the application packages and Tcl script are located. The URL should point to the .pkg file on the FTP server.

In the URL, you can choose to use the username and password of the FTP server. For example:

Router# service-module sm 2/0 install url ftp://username:password@server.com/dir/sre-v-k9-r.SPA.smv.2.0.2.pkg argument keep-ds
 

Step 2 After the upgrade, the content in the disk is retained but you must reconfigure the VMware vSphere Hypervisor, and then add the virtual machines to the inventory.

Bug ID
Summary
Additional Information

CSCuq66676

Router shows incorrect SRE-V version

Symptom: The router shows incorrect SRE-V version, which might indicate that the upgrade did not complete successfully.

Conditions: SRE-V upgrade from 2.0.1 to 2.0.2

Workaround: Although the router indicates incorrect SRE-V version, there was no problem with the upgrade, it was done successfully.

To verify the SRE-V software version, use the service-module sm x/x status command from the VMware ESXi X.0.0 build.

Correct SRE-V software release to ESXi Mapping

  • SRE-V software release 2.0.1.0 maps to ESXi 5.0.0 build-474610
  • SRE-V software release 2.0.2.0 maps to ESXi 5.1.0 build-1065491

DCUI blackout with ESXi5.0

Symptom: DCUI blackout with ESXi5.0.

Conditions: The DCUI screen is not displayed after reloading the router. A separate telnet session does not help either. This problem occurs occasionally, usually after a router reload.

Root cause: The hard-coded hardware flow control in SM PSE2 FPGA blocks DCUI characters and causes ESXi to permanently drop the serial port before reboot.

Workaround: Reload or reset the module to reboot ESXi.

Cannot add deleted datastore

Symptom: Cannot add a deleted datastore.

Conditions: Install the Cisco SRE-V software through the helper. Delete a datastore, and try to add it back to the ESXi host using the VMware vCenter Server. The datastore addition is unsuccessful and displays the following error:

Call "HostDatastoreSystem.CreateVmfsDatastore" for object “datastoreSystem-46” on vcenter server “WIN-ORCICT4IIH8” failed.

This error occurs when the following steps are used:

1. You install Cisco SRE-V software through the helper.

2. You shut down the VMware vCenter Server and remove it from the VMware vCenter Server inventory.

3. You delete the datastore.

4. You add the datastore using the Add Storage wizard.

This is a limitation of ESXi when dealing with a local datastore. More information can be found in this KB article called “Creating a local VMFS volume generates the error. Error during the configuration of the host. Failed to update the disk partition information” at http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1001489

Workaround: From the vmkernel.log you can see that it displays an error that says “partition 1 modification is not supported”, which is addressed in the KB article. The workaround is to use the command line tools as VMware specified in the KB article.
