CISCO 7609 ios upgrade with two engines

[chenyizhen]

HI,all:

I have a router CISCO 7609-S with two RSP 720 engines,and other cards are 7600-

ES+20G3C,7600-ES+40G3C.
One day it has a error cord " %XDR-6-XDRIPCNOTIFY: Message not sent to slot 4/0

(4) because of IPC error queue flush. Disabling linecard. (Expected during

linecard OIR)" and the card resets.Cisco TAC told us it is a bug which is

CSCtj05576.and I want to upgrade the ios from c7600rsp72043-advipservices-

mz.122-33.SRD4.bin to c7600rsp72043-advipservices-mz.122-33.SRE5.bin.
Now I want to know this:
1, Is it right to upgrade to this new ios? Is the new ios suitable for the

cards?
2,I want to know the right way to upgrade ios in two engines.Atfer I copy the

new ios to the master engine and slave engine,and then change the bootvar and

save config.Is it auto copy the config to de slave engine?Atfer do this ,I want

to know how to apply the new ios,Does it  reload the slave engine first and then

force-switchover the master engine to slave engine. Or Atfer do this,I reload

the router on active engine directly?

Hi,

1. SRE5 should be good choice but still all depends on your environment and features used

2. You can use this procedure explaining upgarde on 6500 (same for 7600) in details:

Hope this helps.
