To replace a single appliance in a high-availability (HA) configuration, put the appliance in Admin Down state. This transfers the Active server status to the other appliance. System data is maintained and access control functionality remains available. Next, physically replace the appliance and complete the initial configuration for a Standby server. Once the server is up, system data will be synchronized from the Active HA appliance.
Procedure
Step 1 (Optional) Back up the Active or Standby server.
The backup is not required, but we recommend performing a backup before any major operation.
a. Log in to the Active or Standby appliance.
b. Backup the system data, as described in Backing up the ICPAM Database.
c. Copy the backup file to a local disk.
Step 2 Stop the appliance to be replaced.
a. Log on to the appliance, as described in Logging on to the ICPAM Server Administration Utility.
b. Select Monitoring and then select Status.
c. Click the Stop button to the right of the Admin State entry
d. Verify that the Admin State is Down and the Server Mode is N/A.
Step 3 Power down and physically remove the old appliance.
Step 4 Install the replacement appliance, as described in the Cisco Physical Security Multi Services Platform User Guide.
Step 5 Boot the new appliance and complete the initial configuration for a Standby server.
· Enter a Shared IP Address, as described in Initial Setup Instructions.
· Obtain and reinstall the HA license on the Standby appliance. See Obtaining and Installing Optional Feature Licenses for more information.
Step 6 Wait for the initial setup process to complete.
Step 7 Verify that the redundant servers are in sync.
a. Log in to the appliance.
b. Open the Monitoring > Status window.
c. Verify that there are entries for Peer Address, Hostname, and Sync Status.
If the HA servers are not in sync, see the Monitoring for a description of the HA messages that may appear.
