Installing and Managing the Cisco SRE-V Software
This chapter provides instructions for installing and managing the Cisco SRE-V software.
Note•If you purchased Cisco SRE-V Option 1, a blank Cisco SRE Service Module, you must download and install the Cisco SRE-V software. For Cisco SRE-V options, see Figure 1-3.
•Microsoft Windows software is not available for download from Cisco.com. You must install your own version of the Microsoft Windows Server 2003 or Microsoft Windows Server 2008 software.

Understanding RAID Options
When installing the Cisco SRE-V application on a Cisco SRE 900 Service Module, you can choose to store data files on local Redundant Array of Inexpensive Disks (RAID). The available RAID mode options are: RAID 1, RAID 0, and non-RAID.
Note RAID is not supported on the Cisco SRE 700 Service Module. It is supported on the
Cisco SRE 900 Service Module only.
RAID 1
RAID 1 creates a mirrored set of disk drives, where the data in both the disk drives is identical. See Figure 4-1.
RAID 1 provides high availability. If one disk drive fails, the other disk drive takes over, preserving the datastore.
RAID 1 supports fault tolerance and hot-swapping. When one disk drive fails, you can remove the faulty disk drive and replace it with a new disk drive. See the "Hot-Swapping the Faulty RAID 1 Disk Drive" section on page 7-3.
However, compared to RAID 0, there is less storage space because half of the total potential disk storage space (465 GB) is available and there is a small impact on performance.
Figure 4-1 shows that in RAID 1, the data in Disk 0 and Disk 1 is identical (mirrored).
Figure 4-1 RAID 1 Option—Data in Disk 0 and Disk 1 Is Identical
RAID 0
With RAID 0, the data is stored evenly in stripe blocks across two disk drives without redundancy (mirroring). The data in both the disk drives is different. See Figure 4-2.
Compared to RAID 1, RAID 0 provides additional storage because both the disk drives (927 GB) are used to store data. The performance is improved by two times because the read and write operation occurs in parallel within the two disk drives.
However, there is no fault tolerance, error checking, or hot-swapping. If one disk drive fails, the data in the entire array is destroyed. Because there is no error checking or hot-swapping, the array is susceptible to unrecoverable errors.
Figure 4-2 shows that in RAID 0, the data in Disk 0 and Disk 1 is different. The data is evenly divided across Disk 0 and Disk 1 without redundancy.
Figure 4-2 RAID 0—Data in Disk 0 and Disk 1 Is Different
Non-RAID
When the disk drives of a computer are not configured as RAID, the computer is in non-RAID mode. Non-RAID mode is also referred to as Just a Bunch of Disks or Just a Bunch of Drives (JBOD). Non-RAID mode does not support fault tolerance, error checking, hot-swapping, or redundancy.
Table 4-1 provides a summary of the RAID options.

Downloading the Cisco SRE-V Software
Before you begin downloading the Cisco SRE-V software, do the following:
•Make sure that you have the IP address or name of the FTP server in which you want to store the Cisco SRE-V software package file.
•Verify that the FTP server is accessible.
To download the Cisco SRE-V software, complete the following steps:
Step 1 Go to http://www.cisco.com/go/ucse, click Download Software, and then download the Cisco SRE-V files:
•For Cisco SRE 700 Service Module, download the following .zip file:
sre-v-k9.SPA.smv.1.5.1.zip
•For Cisco SRE 900 Service Module, download the following .zip file:
sre-v-k9-r.SPA.smv.1.5.1.zip
where r in the file name stands for RAID. RAID is supported on the Cisco SRE 900 Service Module only.
Note If you use a file extractor tool designed for Windows, such as WinZip, you must disable CR/LF conversion of tar files. For example, in WinZip 9.0, choose Configuration > Miscellaneous, and then uncheck TAR file smart CR/LF conversion.
Step 2 Extract the zip files to an FTP server. All files to be installed must reside in the same directory.
Step 3 Install the Cisco SRE-V software. See the "Installing the Cisco SRE-V Software—Clean Install" section or the "Upgrading the Cisco SRE-V Software" section as appropriate.

After you successfully install Cisco SRE-V 1.5, and you session into the service module, the console interface is displayed. The console interface allows you to access the VMware vSphere HypervisorTM DCUI to perform Cisco SRE-V configuration. See "Entering and Exiting the VMware vSphere Hypervisor DCUI" section.
If you are a first-time user of the VMware vSphere HypervisorTM, use root for the username; and for the password, leave the field empty. After you login, we recommend that you change the password.

Upgrading the Cisco SRE-V Software
To upgrade the Cisco SRE-V software, complete the following steps:
Step 1 Download the appropriate version of the Cisco SRE-V upgrade software. See the "Downloading the Cisco SRE-V Software" section.
Step 2 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.1.5.1.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.1.5.1.pkg argument keep-ds
Note After the upgrade, the content in the disk is retained but you must reconfigure the VMware vSphere HypervisorTM, and then add the virtual machines to the inventory.

Downgrading the Cisco SRE-V Software from Release 1.5 to 1.1
Before you begin the downgrade process, do the following:
•Export the virtual machines to a remote location.
To downgrade from Cisco SRE-V 1.5 to Cisco SRE-V 1.1, complete the following steps:
Step 1 Download the Cisco SRE-V 1.1 software. See the "Downloading the Cisco SRE-V Software" section.
Step 2 Use the service-module sm slot/0 install url url command to install the Cisco SRE-V 1.1 software, as shown in the following example:
Router# service-module sm slot/0 install url ftp://server.com/dir/sre-v-k9.smv.1.1.1.pkg
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 slot/0 install url ftp://username:password@server.com/dir/sre-v-k9.smv.1.1.1.pkg
Step 3 Choose the RAID mode that you want enabled. During the installation process, you are prompted to choose a disk configuration (RAID mode). The disk configuration options are: 1, 0, or -1.
•1 is RAID 1 mode.
•0 is RAID 0 mode.
•-1 is non-RAID mode.
The service module reboots and the Cisco SRE-V 1.1 software is installed.
Step 4 Reconfigure the VMware vSphere HypervisorTM.
Step 5 Import the virtual machines that you had exported.
Installing Other Cisco Applications on the Cisco SRE Service Module
Before you begin, do the following:
•Export the virtual machines to a remote location.
To install other Cisco applications on the Cisco SRE Service Module, complete the following steps:
Step 1 Download the application that you want to install on the Cisco SRE Service Module.
Step 2 Download the hardware utility. The hardware utility is used to change the SATA mode from AHCI to IDE.
Step 3 Use the service-module sm slot/0 install url url/sm-hw-uti1.1.1.x argument sata-mode=ide command to change the SATA mode from AHCI to IDE:
Router# service-module sm slot/0 install url url/sm-hw-uti1.1.1.x argument sata-mode=ide
Step 4 Use the service-module sm slot/0 install url application_url command to install the software, as shown in the following example:
Router# service-module sm slot/0 install url application_url.pkg
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.
The service module reboots and the application is installed.
Installing the VMware vSphere Hypervisor Patch or Update Release
VMware vSphere HypervisorTM patches and update releases are available periodically on an as-needed basis from Cisco.com.
To install the VMware vSphere HypervisorTM patch or update release, complete the following steps:
Step 1 Download the patch or update release (as appropriate) from Cisco.com.
Note Do not download the patch or update release from VMware.
Step 2 Use the update utility provided by VMware to install the patch or update release.
