Unable to connect to standby(COLD) SUP720

[sanjeevreddyallala]

Hi there,

1. I have a SUP720 versioning problem for my two SUP720 engines in 6509 so the redundancy is in bellow state.

sw01#show redundancy

Configured Redundancy Mode = sso
     Operating Redundancy Mode = rpr

sw01#show mod

  5    2  Supervisor Engine 720 (Cold)           WS-SUP720-3B       SAL1201C1FK
  6    2  Supervisor Engine 720 (Active)         WS-SUP720-3B       SAL1201C1M4  <------------active

  5  0016.46f9.8928 to 0016.46f9.892b   5.6   8.5(2)       12.2(33)SXH  Ok
  6  0016.c848.2b18 to 0016.c848.2b1b   5.6   8.5(2)       12.2(18)SXF7 Ok <-----------active

boot system flash sup-bootdisk:

2. I am trying to establish a session to slot 5 but unable to connect.

sw01#session slot 5 processor 0

3. I am planning to copy the IOS across the SUP720 in slot 6 to slot5 and then reset the standby SUP720 with "redundancy reload" command.

to achieve High availability mode SSO (sso already configured).

could you please advice?

Hi Sanjeev,

Which version did you want to upgrade to? Assuming you wanted to get to SXH IOS

1. Could you do a

#dir sup-bootdisk:   <<--- displays active

#dir slavesup-bootdisk:   <<--- displays standby

You should be able to copy images between the two

eg. #copy sup-bootdisk: slavesup-bootdisk:

IOS will prompt you for the image name etc

You can also do a verify to check if it's copied properly

#verify slavesup-bootdisk:[image name]

2. You can't session to a standby SUP via telnet. You can see things on the standby console but you can't access it.

You can #remote login standby

3. If you wanted to get to SXH, then after ensuring all the images and boot variables are OK, you would #red force-switchover

this will make SLOT5 active and SLOT6 would boot to the new image.

From memory, As you are in RPR mode, this could be up to a 30- 60 second interruption to traffic during the switchover

HTH

P.S Recommend that you'd have console access during the upgrade process just in case.
