Dell C1048P Port Extender Networking Configuration Guide for the C9000 Series - Page 94

C9000-9.9.0.0.bin {A: | B:} command. For information about this upgrade procedure, see the C9010 and C1048P Release Notes. By upgrading all C9010 components at the same time, you ensure that all system images match. However, sometimes the loaded system images do not match as a result of booting off a system image stored on a network server or installing an additional line card or RPM. When system images on C9010 components do not match, the RPM CP may not be able to manage them. For example, if the RPM RP image does not match the RPM CP image, the console port of the RPM CP may not fully come up. As a result, the command-line prompt may not appear on the C9010 console. When the system detects an image mismatch, it automatically performs a firmware synchronization to ensure that all C9010 component images are the same as the RPM CP image; for example: %RPM0-P:CP %DOWNLOAD-6-VERSION_MISMATCH_INFO: Received checkin from linecard 0. Expected version = 1-0(0-4243) checkin version = 1-0(0-4226) %RPM0-P:CP %DOWNLOAD-6-UPGRADE_PROGRESS: Linecard 0 firmware auto sync is in progress. If the automatic synchronization of component images fails or if the RPM CP cannot read line-card firmware, you can manually reset the system image on an individual component. Manually Resetting the System Image on a C9010 Component If the image running on the RPM CP does not match the image on a C9010 component, you can manually recover from the mismatch as follows: 1 Log in to the virtual console of the C9010 component as described in Logging in to the Virtual Console of a C9010 Component. 2 Display the boot variables that you need to configure so that the component boots from the RPM CP image by entering the show bootvar command at the BOOT_USER# prompt. show bootvar See Configuring C9010 Components to Boot from the RPM CP Image for examples. 3 Reconfigure the boot variables of the component by entering the boot change command at the BOOT_USER# prompt. boot change {primary | secondary | default} You are prompted to enter boot variables by specifying a path (for example, using FTP or TFTP) or system filename for the Dell Networking OS image that you want to load. Enter the component's boot parameters displayed in the show bootvar output. 4 Reload the C9010 component by entering the reload command at the BOOT_USER# prompt. 5 Log out of the virtual console of the C9010 component and log back in to the RPM CP (C9010 console) as described in Logging in to the Virtual Console of a C9010 Component. You can also recover from an image mismatch on a C9010 component by rebooting the C9010 from an RPM CP image stored on a network server. See Booting a C9010 Component from an Image on a Network Server for more information. Switch Management 94
