If you have an IRF of these chassis-based switches and just reboot the entire cluster then break the boot sequence
and bypass the current config, when the switch reboots it will load the config
from MPU 1/1 or 2/0 or 2/1. Therefore
I had to isolate myself to a single MPU. The steps that I had to do to
recover was:
· Break
the IRF by unplugging IRF physical interfaces (te1/2/0/15 and te1/2/0/16 in
this case).
·
Pull
the standby CPU from slot 1 in chassis 1 (1/1)
·
Connect
console cable to chassis 1 slot 0 MPU (1/0)
·
Reboot
switch
·
Stop
with control B at bootrom (screen output and selections are listed below)

Switch
will now reboot without current config
·
Load
current config with “config replace file flash:/config.cfg” command. The
switch will load the mangled startup-config file into current configuration but
will NOT log you out.
·
At
a minimum, 1) strip the console password and add privilege level 3, and 2)
create a temporary local user with terminal access and privilege level 3.
(user "admin" with password “hp” in below example).
user-interface con
1/0 2/1
authentication-mode
none
user privilege
level 3
local-user admin
password simple hp
authorization-attribute
level 3
service-type ssh
telnet terminal
·
Add
back irf-port 1/1 (it gets stripped from config when it is pulled in via the
“config replace .. “ command.
int ran
te1/2/0/15 to te1/2/0/16
shut
quit
irf-port 1/1
port group int
te1/2/0/15
port group int te1/2/0/16
quit
int ran
te1/2/0/15 to te1/2/0/16
undo shut
quit
·
Save
config. Verify the changes in the current config with “more” command from
user context
·
Insert
MPU in chassis 1 slot 1
·
Verify
it comes up and replaces MPU slot 1/1 config.cfg with MPU 1/0 config.sys1/1
dis device ß verify slot loads
with correct code version
copy config.sys
chassis1#slot1#flash:/config.sys
·
Connect
irf links (te1/2/0/15 and te1/2/0/16)
·
Verify
in logbuffer that the switch detects that there is an irf merge
%Dec 18 11:48:16:274
2015 hp IFNET/3/LINK_UPDOWN: Ten-GigabitEthernet1/2/0/15 link status is
UP.
%Dec 18
11:48:21:845 2015 hp IFNET/3/LINK_UPDOWN: Ten-GigabitEthernet1/2/0/16
link status is UP.
IRF merge occurs and the IRF system does not need to reboot.
%Dec 18
11:48:27:391 2015 hp STM/5/STM_MERGE:
·
Reboot
switch 2
·
Verify
that all modules load with the correct version of code (dis device)
·
After
switch 2 comes up, replace MPU’s 2/0 and 2/1 config.cfg with MPU 1/0 config.sys
