Chapter 3 Managing and Monitoring the Health of Cisco Unified Communications Manager Systems
Platform Monitoring
These tools support writing backup files to (or reading restore files from) a local tape drive, or a file on
a network location. BARS uses Windows shares and DRF/DRS use SFTP to access the network
location. If a third-party backup solution is desired, BARS/DRF/DRS can write to a network location
for the third-party backup solution to pick up.
DRF/DRS perform a cluster-wide backup, meaning data from all nodes is backed up, but restores are
only to the node (s) that need it.
For more details, including what is configured to be included in the backup or what files are created,
refer to the following documents depending on release:
• Disaster Recovery Administration Guide
•
Cisco IP Telephony Disaster Recovery Administration Guide
• Cisco IP Telephony Backup and Restore System (BARS) Administration Guide
It is recommended to take a fresh backup every time an install, upgrade or options install is done to the
appliance, whether or not configuration data changes were made.
If a catastrophic hardware failure occurs and the hardware must be replaced, reinstall Cisco Unified CM
on the new hardware, then perform a restore from your backup.
Note Drive pull/swap is not supported as a fast recovery solution for the appliance.
Refer to the Replacing a Single Server or Cluster for Cisco Unified Communications Manager chapter
of your release of Cisco Unified Communications Manager Install and Upgrade Guide at this index:

Platform Monitoring
This section describes hardware-layer monitoring for system component temperature, fan status, power
supply status, RAID and disk status, network status, and operational status. CPU status/utilization and
Memory status/utilization are covered in another section. It contains the following subsections:
• Using SNMP MIBs, page 3-27
•
Using Command Line Interface, page 3-28
• Hardware Migration, page 3-31
•
Platform Security, page 3-31
Using SNMP MIBs
Cisco Unified CM hardware servers are monitored by using SNMP MIBs. The following MIBs are
supported:
•
Vendor-Specific MIBs ( Chapter 9, “Vendor-Specific Management Information Base” )
– IBM-SYSTEM-LMSENSOR
–
IBM-SYSTEM-POWER
– IBM-SYSTEM-RAID
