SMC RAID Support
Each SMC is equipped with a hard disk, commonly referred to as a Small Form Factor (SFF) disk.
Important: The hard disk is not physically accessible. Disk failure constitutes an SMC failure.
If there is a redundant SMC in the chassis, the standby disk mirror the disk in the active SMC, forming an active
Redundant Array of Inexpensive Disks (RAID).
HD RAID ids configurable via CLI commands. RAID control mechanisms allow xDR charging data to be written to the
hard disks on both the active and standby SMCs for later upload to a suitable local or remote storage server.
Event logs related to disk and RAID include disk name, serial number and RAID UUID for reference. They are
generated at the Critical, Error, Warning, and Informational levels.
Event logs at the Critical level are generated for service-affecting events such as:
 RAID failure, including failures during runtime and various cases of initial RAID discovery and disk partition
failures
 File system failure when the system fails to initialize or mount file systems
 Network failure for NFS server-related errors
Event logs at the Error level are generated for important failures:
 RAID disk failure, including failures during runtime
 Internal errors, including forking process failures
Event logs at Warning level are generated for important abnormal cases:
 Overwriting a valid or invalid disk partition, RAID image, and file system
 RAID construction in progress and possible failure
 Low disk space
 Files deleted to free up disk space
Event logs at the Informational level are generated for normal situations:
 Disk partition completion
 RAID discovery results without overwriting
 RAID construction completion
 RAID disk added or removed
 File system initialization
 NFS service start
