WRTMT

WRTMT

Performs a write/read test.

Syntax

wrtmt

Description

This command performs a write-then-read test on the selected disk. It is designed to test only
internal disks and not the array itself. Use either the

enclosure

looppair

, and

slot

commands or the

fru

command to select the disk for testing. Pressing either Ctrl-c or Ctrl-y causes the test to abort.

WARNING! This is a destructive command and can cause data loss.

Example

To execute a test on disk 2 in the main enclosure:

VADIAG> fru m/d2

VADIAG> wrtmt
