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.
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 an 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 also improved.
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.
|
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 Copy the files to the 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.

Downgrading the Cisco SRE-V Software
Before you begin the downgrade process, do the following:
•Export the virtual machines to a remote location. See the "Exporting the Virtual Machine to a Remote Location" section.
To downgrade from Cisco SRE-V 1.1 to Cisco SRE-V 1.0, complete the following steps:
Step 1 Download the Cisco SRE-V 1.0 software. See the "Downloading the Cisco SRE-V Software" section.
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 url command to install the Cisco SRE-V 1.0 software, as shown in the following example:
Router# ftp://server.com/dir/sre-v-k9.smv.1.1.0.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 Cisco SRE-V 1.0 software is installed.
Step 5 Import the virtual machines that you had exported. See Importing the Virtual Machine to VMware vSphere Hypervisor.
Installing Other Cisco Applications on Cisco SRE Service Module
Before you begin, do the following:
•Export the virtual machines to a remote location. See Exporting the Virtual Machine 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:
SRE-Module# software install package url ftp://server.com/dir/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 Cisco SRE-V 1.0 software is installed.
Step 5 Import the virtual machines that you had exported. See Importing the Virtual Machine to VMware vSphere Hypervisor.
Upgrading the VMware vSphere Hypervisor Package
VMware vSphere HypervisorTM update packages (patch) are available periodically on an as-needed basis. To upgrade the package, you must first download the update package, and then install it on the VMware vSphere HypervisorTM. See the following sections for more information:
