UniPack Upgrades to SR 2.5/3.5 and SR 
4.0 Require New DBDS Maintenance CD 

 

Cisco engineers have discovered that upgrades of system software to System Release 
(SR) 2.5/3.5 and SR 4.0, that use the Solaris Live Upgrade process, may fail during 
execution of the detach_DBmirrors script. Specifically, the script has been known to 
fail on an Enterprise 450 Digital Network Control System (DNCS) server that uses a 
10 x 9 gigabyte (GB) disk configuration. 

Notes: 

 

The Solaris Live Upgrade process allows the Enterprise 450 and Sun Fire V880 
DNCS servers to be upgraded through use of the UniPack without shutting 
down system processes until activation of the new system software. 

 

UniPack upgrades to SR 2.5/3.5 and SR 4.0 use the Solaris Live Upgrade process. 

Important!  The detach_DBmirrors script works as intended on all other disk 
configurations. 

 

This technical bulletin alerts system operators and installation engineers to the issue 
with the detach_DBmirrors script when used on an Enterprise 450 DNCS server that 
uses a 10 x 9 GB disk configuration. In addition, this technical bulletin advises 
system operators and installation engineers to obtain an updated version of the 
DBDS Maintenance CD before undertaking a UniPack Live Upgrade on the specified 
server.
