Maintaining a Storage Array

115

Maintaining a Storage Array

Maintenance covers a broad spectrum of activities. Its goal is to keep a storage

array operational and available to all hosts. This chapter provides descriptions

of command line interface (CLI) and script commands that you can use to

perform storage array maintenance. The commands are organized into four

sections:

• Routine maintenance
• Performance tuning
• Troubleshooting and diagnostics
• Recovery operations

The organization is not a rigid approach, and you can use the commands as

appropriate for your storage array. The commands listed in this chapter do not

cover the entire array of commands you can use for maintenance. Other

commands, particularly the

set

commands, can provide diagnostic or

maintenance capabilities.

Routine Maintenance

Routine maintenance involves those tasks you might perform periodically to

ensure that the storage array is running as well as possible or to detect

conditions before they become problems.

Running a Media Scan

Media scan provides a method of detecting physical disk media errors before

they are found during a normal read from or write to the physical disks. Any

errors detected are reported to the Major Event Log (MEL). Media scan

provides an early indication of a potential drive failure and reduces the

possibility of encountering a media error during host operations. A media

scan is performed as a background operation and scans all data and

consistency information in defined user virtual disks.
