In-Depth Information
Disaster Recovery System Interface
The Disaster Recovery System (DRS) provides a backup (with scheduler) and restore capa-
bility. Access to this interface uses the Platform Administration account defined at install
(as does the OS Admin interface). Additional accounts can be created for access by other
individuals.
Backups can be written to a local DLT tape drive or to an SFTP server. A scheduler is pro-
vided for automated backups, or an immediate start to the backup can be selected. Indi-
vidual server or full cluster backups may be performed.
Cisco Unified Reporting Interface
The Cisco Unified Reporting interface provides a simplified method to access system re-
ports. These reports gather information from existing logs and format the data into sim-
ple, useful, one-click reports. Data is collected from logs across the cluster (Publisher and
Subscribers) to provide summarized information and highlight issues or irregularities
that might impact operation of the cluster. The interface also warns if running a particu-
lar report could adversely impact server operation and affect performance or take exces-
sive time.
CLI
The CLI is typically accessed using SSH, although it is possible to directly connect a key-
board and monitor. Initially, the only account that can log on using the CLI is the Platform
Administration account defined during install, although additional accounts can be cre-
ated to allow access.
The commands and functionalities of the CLI include all those found in the OS Adminis-
tration interface, plus the following (this is not a comprehensive list):
Shut down or restart the system
Change versions after an upgrade
Start, stop, and restart services
Modify network settings (IP Address, mask, gateway, and so on)
Use network tools such as ping, traceroute, and packet capture
Use the DRS (backup and restore)
Add and modify Platform Administration accounts
Display server load and process information
Check server status, including software versions, CPU, memory and disk utilization,
hardware platform, and serial numbers, and so on
Inline help is available for the CLI using the question mark (?) in a similar fashion to the
Cisco router IOS.
