Dell PowerConnect B-RX Multi-Service IronWare Software Release 02.8.00a Releas - Page 25

• If you copied the primary and/or secondary IronWare image to all interface modules using the copy command with the all keyword, the management module made a copy of the image and stored it in its code flash under the names lp-primary-0 or lp-secondary-0. By default, the BigIron RX system checks the interface modules' IronWare images, which reside in the code flash of the interface modules and the management module to make sure they are the same in both locations. (These IronWare images are stored on the management module only and are not run by the management or interface modules.) If the IronWare images on the interface and management modules are different, the system prompts you to do the following: • If you want to update the IronWare images in the interface module's code flash with the images in the management module's code flash, enter the lp cont-boot sync command at the Privileged EXEC prompt. • If you want to retain the IronWare images in the interface module's code flash, enter the lp cont-boot no-sync command at the Privileged EXEC prompt. After the management module finishes booting, do the following: • Enter the show module command at any CLI level, and verify that the status of all interface modules is CARD_STATE_UP. • Enter the show version command at any CLI level, and verify that all management and interface modules are running the new software image version. If you find that an interface module is in a waiting state or is running an older software image, then you may have not entered the lp cont-boot sync command at the Privileged EXEC prompt. You also need to upgrade the MBRIDGE FPGA on the management module. Regenerating SSH v2 crypto key If you are using SSH v2, you must clear the crypto key using the crypto key zeroize command after you upgrade from any release 02.2.01 and later. Then, you must regenerate a new crypto key using the crypto key generate command. Hitless Layer 2 OS Upgrade Hitless OS upgrades are supported for Layer 2 switching and Layer 2 protocols only. See the Upgrading Software Images and Configuration Files chapter in the BigIron RX Series Installation Guide for additional information. The hitless OS Layer 2 upgrade allows for upgrading the software in a system between two patch releases of the operating system, which support this functionality and have compatible data structures. A hitless OS Layer 2 downgrade may also be supported if the current and target code releases have compatible data structures. Note: Hitless OS upgrade is not supported between major releases. It is supported only within a release. For example, Hitless OS Upgrade is available when upgrading from software release 02.8.00a to 02.8.00b. It is not available when upgrading from software release 02.7.00 to 02.8.00. From time to time, it may become necessary when enhancing the software or adding new features to change or add data structures making releases incompatible. In these cases, an upgrade or downgrade will not be hitless, and will fall back to using the regular Brocade upgrade process - relying on fast reboot.
