RNCS Rollback Procedure 

78-4003191-01 Rev B 

If your upgrade of RNCS software is unsuccessful, you may need to use the 

procedures in this appendix to restore your system to its condition prior to the 

upgrade. 
Note:  For this procedure to work, you must not yet have reattached the disk 

mirrors. 
Important:  Be sure to notify Cisco Services before concluding that an upgrade has 

failed and before following any of the procedures in this section. In many cases, 

Cisco Services can help you easily resolve the problems related to the failed upgrade. 

Follow these instructions to roll back from an unsuccessful upgrade of RNCS 

software. 
Note:  You should still be remotely logged in to the RNCS server with root 

permissions.
