Special Procedures

Step 3 If there is a redundant NP in this chassis, verify that the other NP is functioning as backup.

Enter the following command:

bash# rsh other-np /bin/true

The following results are possible:

• No error message

bash# rsh other-np /bin/true

bash#

This result indicates success. The other NP is up and accessible. Return to the section

thatreferred you to this Special Procedure (“Procedure3, Change theRunning Software

Version”).

• Connection timed out (the timeout takes about 75 seconds)

bash# rsh other-np /bin/true

other-np: connection timed out

bash#

This result indicates that the backup NP is not up. Go to Step 4.

• Permission denied

bash# rsh other-np /bin/true

Permission denied.

bash#

This result indicates that the backup NP is up, but not accessible because of a

permissions mismatch. Go to Step 4.

Step 4 The following error message may be generated (after about 75 seconds):

other-np: connection timed out

If this message is displayed, reset the other NP:

• Return to the TCS by typing ‘. (backquote plus dot, that is, left single quote plus period).

• Monitor the reboot, looking for the following two trap messages:

==> (OPER) NDD_2 at mm/dd/yy/ hh:mm:ss <time-zone> (mm/dd/yy hh:mm:ss GMT)

Network Processor <node_name:slot> becoming backup np

==> (GENERIC) at mm/dd/yy/ hh:mm:ss <time-zone> (mm/dd/yy hh:mm:ss GMT)

Cold Start Trap at mm/dd/yy hh:mm:ss <time-zone> (mm/dd/yy hh:mm:ss GMT)

Note You may have to wait about 5 minutes for these traps to appear.
