How to Maintain Hard Disk Drives

The management console contains several tables that it consistently accesses for read/write operations. These tables occupy most of the disk space on the drive where the management console is installed. These I/O operations might cause disk fragmentation over time.

To maintain the hard disk drives, perform the following tasks:

• For databases larger than 10 gigabytes, defragment the D: drive or the drive on which the management console is installed each month.
  • Ensure that at least 20% of this drive contains free disk space before starting the defragmentation process.
  • Stop all CA ADA-related services, including the CA MySql service, before defragmentation.
  • Restart these processes after the defragmentation finishes.
• CA products are constantly writing to disk. During data seek for report compilations, the drive heads simultaneously write and read. As with any disk drive, this stress over time could lead to failure. To recover quickly with minimal data loss, schedule a regular database backup.
