Hi,
I have used ISSU for 6509 VSS to upgrade the IOS From s72033-adventerprise_wan-vz.122-33.SXI5.bin,12 to s72033-adventerprisek9_wan-vz.122-33.SXI5.bin,12; version
I have referred below link for ISSU
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/issu_efsu.html#wpxref41569
As per the document there will not be any network outage if we do ISSU for the IOS ver SXI. The upgrade was success, but I got a network outage of 5 min...Please let me know why it took 5 min Network outage.
Below are the steps followed:-
1) The command issu loadversion sup-bootdisk:s72033-adventerprisek9_wan-vz.122-33.SXI5.bin reload the standby Sup and booted with the new IOS but the Standby sup becomes STANDBY COLD and the redundancy mode becomes RPR mode.
O/P’s as below
CORE#sh issu state
Slot = 1/5
RP State = Active
ISSU State = Load Version
Boot Variable = bootdisk:s72033-adventerprise_wan-vz.122-33.SXI5.bin,12
% Standby information is not available because it is in 'DISABLED' state
CORE#sh issu state
Slot = 1/5
RP State = Active
ISSU State = Load Version
Boot Variable = bootdisk:s72033-adventerprise_wan-vz.122-33.SXI5.bin,12
% Standby information is not available because it is in 'DISABLED' state
CORE#sh issu state
Slot = 1/5
RP State = Active
ISSU State = Load Version
Boot Variable = bootdisk:s72033-adventerprise_wan-vz.122-33.SXI5.bin,12
Slot = 2/5
RP State = Standby
ISSU State = Load Version
Boot Variable = bootdisk:s72033-adventerprisek9_wan-vz.122-33.SXI5.bin,12;bootdisk:s72033-adventerprise_wan-vz.122-33.SXI5.bin,12

2) The command issu runversion , initialized the standby sup to Active but it took 5 min to make the standby SUP to Active.
3) Then completed the upgrade with the commands ISSU acceptversion and ISSU commitversion.
Please let me know why the Standby SUP initialized on RPR mode instead of SSO.
