Downgrading from Release 2.4.1
This chapter describes the downgrade procedure for the CDSM, VVIM, and CDS servers. The chapter covers the following topics:
•Downgrading the Software on a CDSM or VVIM
Downgrading the Software on a CDSM or VVIM
If the VVI or CDS has redundant VVIMs or CDSMs, downgrade the secondary CDSM or VVIM first, then downgrade the primary.
The primary and secondary CDSM (or VVIM) can be determined by entering the ifconfig -a | more command. The primary has the following output:
eth0:1 Link encap:Ethernet HWaddr 00:11:00:00:00:00
inet addr:172.22.98.54 Bcast:172.22.99.255 Mask:255.255.254.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
The primary CDSM has device eth0:1. The secondary CDSM does not have the virtual IP address as up.
Note Downgrading a CDSM requires that the TV CDS ISO image file has been downloaded and copied to the CDSM and if applicable, VVIM. Before downgrading the software, review the information in the "Introduction" section. For information on downloading the software files, see the "Getting the Cisco TV CDS Software Files for Release 2.4.1" section.
To downgrade the software on a CDSM or VVIM, do the following:
Step 1 Log in to the CDSM as root. Log in to the secondary CDSM and downgrade it first, if redundant CDSMs exist.
Step 2 Restore the configuration and database files from the backup that was created as part of the upgrade procedure. For information on this procedure, see the "Performing a Restore on the CDSM" section.
Step 3 Run the cdsinstall script to downgrade the software using the ISO image file downloaded from the Cisco software download website. In the following example, the CDSM is downgraded to Release 2.1.3:
# ./cdsinstall /CDS-TV-2.1.3.iso
Select Deployment Type (ctrl-c to quit):
Step 4 Reboot the CDSM.
Step 5 Downgrade the primary CDSM (Step 1 to Step 4), if applicable.
