Dell PowerVault ME4 Series Storage System Deployment Guide

Host I/O

When troubleshooting disk drive and connectivity faults, stop I/O to the affected disk groups from all hosts as a data protection precaution.

As an extra data protection precaution, it is helpful to conduct regularly scheduled backups of your data. See “Stopping I/O” in the Dell PowerVault ME4 Series Storage System Owner’s Manual.
