Configuring High System Availability
| Command | Purpose |
|
|
|
Step 5 | Router(config)# boot system flash bootflash:[filename] | Configures the active RSP to boot the new image from |
| or | the appropriate location. |
|
| |
| Router(config)# boot system flash slot0:[filename] | Note In this procedure, the image that you specify in |
| this command only resides on the first, or active, | |
| or | |
| RSP. | |
| Router(config)# boot system flash slot1:[filename] |
|
|
|
|
Step 6 | Router(config)# boot system flash bootflash:[filename] | Configures a second boot system command that |
| or | specifies the boot image and location on the standby |
| RSP. | |
| Router(config)# boot system flash slot0:[filename] | |
| Note This is the boot image that the standby uses | |
| or | |
| when it boots the system as the active RSP, | |
| Router(config)# boot system flash slot1:[filename] | assuming that the image file that you specified in |
|
| the first boot system command does not exist on |
|
| the second RSP. Therefore, when the standby |
|
| RSP cannot locate the image in the first boot |
|
| system command, it uses the image specified in |
|
| this second command. |
|
|
|
Step 7 | Router(config)# boot system {rcp tftp ftp} filename | (Optional) Configures the active RSP to boot from a |
|
| network server. |
|
|
|
Step 8 | Router(config)# | Sets the configuration register to enable loading of the |
|
| system image from a network server or Flash memory. |
|
|
|
Step 9 | Router(config)# end | Exits global configuration mode and returns you to |
|
| privileged EXEC configuration mode. |
|
|
|
Step 10 | Router# copy | Saves the configuration file to the active RSP startup |
|
| configuration. Because automatic synchronization is |
|
| turned on, this step saves the boot system commands to |
|
| the active and the standby startup configuration. |
|
|
|
Step 11 | Router# reload | Resets the router with the new configuration |
|
| information. |

Upgrading to a New Software Version Example
Note The following examples show systems with two RSP8s.
The following example describes an upgrade scenario under the following conditions:
•The active RSP8 is in processor slot 6, and the standby RSP8 is in processor slot 7 of a Cisco 7513 or Cisco
•Both the active and the standby RSPs currently use the same Cisco IOS Enterprise image,
•We want to upgrade one RSP to run Cisco IOS Release 12.0(22.3)S1, and allow the other RSP to run Cisco IOS Release 12.0(23)S. To guard against software failures, we will configure HSA operation for software error protection.
