Hi guys, We have a VSS setup on a pair of 6509-E Chassis, and we¹re currently running Version 12.2(33)SXH6. Due to a desire for some features, and the ability to run FWSM¹s in this configuration, we¹re wanting to upgrade to SXI.
After some discussions, it was decided that we¹d first go from SXH6 Modular to SXH6 monolithic, then schedule in another upgrade for SXH6 Monolithic to SXI, however, we¹ve hit a bump with the Modular > Monolithic change. Procedure we followed was:- TFTP'd software images to both SUPS ahead of schedule, and did the following. * No Boot System * Config-Register 0x2102 * Boot System Flash sup-bootdisk:s72033-advipservicesk9-mz.122-33.SXH6.bin (The non-modular image installed) * Write mem (this should sync the bootvar across the two chassis, telling both supervisors to boot the new image upon reload) * Redundancy reload shelf 2 (to reload the standby. Chassis 1 is active.) At this point, the failover should be RPR mode, chassis 2 boots off the new IOS image, and we¹re at 50% off the current active chassis. My next step would be ³redundancy force switchover² to failover to the other chassis, and re-boot this currently active unit with the new code. However, the 2nd chassis re-boots, and goes right back into SSO mode. Looking at it boot through console, you can see it booting the Modular image from the /sys folder, seemingly ignoring anything the bootvar is set-to, so essentially, it¹s re-booting with no change, and just re-pairing with the VSS, which is why it¹s re-entering SSO immediately. At first I thought because it was the same IOS version, just modular/non modular, that it may still be enabling SSO although the IOS images are the same version, just modular/monolithic, but it¹s definitely the modular image that is being loaded. It¹s the only line in the ³boot-start-marker² in the config, and the other lines have been removed, but it still re-boots on the modular image every time. Henceforth, I'm stuck! I can't get the standby sup to boot off the new image and go into RPR, and I don't want to reload both boxes at the same time with no confidence it's going to work. Anyone any idea what's going on? Thanks, Dave. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
